PROVENANCE
The property of Elizabeth Sarah Jay, née Morgan, thence by descent.
$ 20,000-30,000
Elizabeth Sarah Jay, née Morgan (1889-1975), was born in New York City and raised at Wheatly, the Morgan family estate in Old Westbury, Long Island. A woman of striking beauty, she was the great-granddaughter of Edwin Denison Morgan, 21st Governor of New York and Civil War general. Her husband, Delancy Kane Jay, was a direct descendent of John Jay, first Chief Justice of the United States.
Family lore has it that the necklace was a gift from distant relation John Pierpont Morgan for her wedding, in 1910, though the necklace dates to the late 19th century. It is an unusual and compelling example of René Lalique’s early work. Composed of white diamonds set traditionally in silver-topped gold, the necklace differs from the more colorful natureinspired motifs of Lalique’s mature Art Nouveau style, but its sinuous lines and inventive design already reveal the master jeweler’s talent.

Few gemstones have captivated the international collecting community in recent years as have Paraíba tourmalines. Named after the region of northeastern Brazil where they were first discovered in the late 1980s, this rare variety is distinguished by its vivid green to blue color that, when bearing sufficient levels of copper, take on a neon or “electric” appearance.
The present collection was acquired by the scion of an American communications empire founded in the early 1900s. Through his work fundraising for the Juvenile Diabetes Research Foundation, he befriended a member one of Colorado’s premier jewelry firms who introduced him to Paraíba tourmalines, then essentially unknown to all but the most serious “rockhounds.” He soon caught the collecting bug, and the call went out to find the best examples in the market, resulting in the five exceptionally clean and vibrant examples offered here.

In December 2020, Sotheby’s introduced the Captivated by Color Collection to a worldwide audience. Among the twenty-one jewels offered in that season’s Magnificent Jewels auction were extremely rare orange and red diamonds, Kashmir and padparadscha sapphires, technicolor opals, and a no-oil emerald. Captivated by Color returned in 2022 with two exceptional alexandrites that established a new benchmark for Brazilian-mined examples. As done with so many of her specimen-quality stones, the consignor entrusted Oscar Heyman & Brothers to devise mountings, forming what is possibly the most extensive and important collection of “OHB” in existence.
The jewels from Captivated by Color across our June 2026 auctions High and Fine Jewelry (lots 29-31 and 219-221) further reveal one woman’s passion for the extraordinary colors and optical properties found in the world of gemstones. An accomplished businesswoman, she approaches collecting as a serious discipline, absorbing information from a variety of sources and applying it to her collaborations with jewelers, often creating one-of-a-kind pieces. Through prescient connoisseurship, she has pursued certain categories well in advance of market surges, notably Paraíba tourmalines and stones sourced from Africa.
Sotheby’s is honored, once again, to present jewels and gemstones from this remarkable collection.

Diamonds are miracles of nature. Their creation requires a complex chain of geological conditions, yet the result is exquisitely simple: a dazzling crystal of pure carbon. A diamond’s rarity, unmatched hardness and brilliance have made it an enduring symbol of purity, strength and prestige across civilizations for thousands of years.
Long before their origins were fully understood, diamonds were revered for what were perceived to be their mystical and divine properties. In India, the oldest known source for diamonds, warriors and spiritual leaders prized them as indestructible amulets, protecting against evil spirits and harm. In the Diamond Sutra, one of the most influential Buddhist texts, the stone represents supreme wisdom and clarity, cutting through illusion to achieve a full awakening of mind and spirit. The Ancient Greeks and Romans believed diamonds to be fragments of fallen stars or the tears of the gods, and Cupid’s bow was said to be diamond-tipped, able to pierce the most hardened of hearts. Centuries later, the Silk Road and Venetian trade routes brought diamonds to Europe where they became symbols of wealth and power. While no longer thought to fall from the heavens, diamonds’ rarity and beauty continue to inspire.
A diamond jewel is a collaboration between nature and craftsman. Each diamond rough is transformed through thoughtful cutting and polishing to tease out its full potential. The cutter analyzes the rough and determines what it shall become: a round brilliant to maximize light return and fire? A step cut to showcase
the purity of the material? Or, perhaps, an old mine cut, a style developed centuries ago and most often found in antique jewels, from tiaras to rivières. The cut is distinguished by its cushion-shaped outline, broad facets and open culet, all of which lend the stone a distinct character and charm. Famous old mine-cut diamonds include the Hope, the Tiffany Yellow and the Grand Mazarin. The scarcity of diamonds has led many of these stones, particularly larger specimens, to be recut in order to align with modern specifications. Recently, there has been a renewed appreciation for old mine cuts, both for their beauty and their association with the grandeur of yesteryear.
The exquisite elongated old mine-cut diamond offered as lot 34 represents the continuation of a partnership between De Beers and Sotheby’s that celebrates diamonds as cultural icons and works of art. In addition to its cut, the diamond’s Type IIa classification brings to mind the legendary diamonds of Golconda, admired for their exceptional optical transparency. In April, Sotheby’s Hong Kong offered the Jwaneng 28.88, a spectacular modern round brilliant with excellent polish and symmetry. This was followed by a pair of perfectly matched 18.38-carat round diamonds at Sotheby’s Geneva this May, also with excellent polish and symmetry. All three diamonds were cut with extraordinary precision in accordance with Marcel Tolkowsky’s ground-breaking prescription for the modern round brilliant cut developed in 1919. Lot 34, however, was carefully faceted in an intentionally nonformulaic manner to reflect the human touch and to lend the stone its unique, captivating character.

Diamonds are one of nature’s greatest and most beautiful treasures, formed up to 3 billion years ago, and found in some of the world’s most remote,

Every old mine cut diamond carries not only the memory of the earth, but the imprint of the human hand. To examine one closely is to hold a decision: the cutter’s pause, the angle chosen by eye rather than instrument.
The Old Mine Brilliant cut represents one of the most significant chapters in the history of diamond fashioning. The present stone, at 11.33 carats, and shaped by Botswana, is a substantial example. Diamonds of this cut at this weight are not common; those that also carry D colour and VVS2 clarity are rarer still. The combination places it among a very limited category of old mine brilliants in which historical form and top-grade gemological quality coincide.
This lot reflects a broader shift in how the market values Old Mine Cuts, not as curiosities or alternatives to modern stones, but as objects with their own history, their own material logic and, increasingly, their own distinct demand. The individuality of this stone, the slight variations in outline, the facet geometry that follows the character of the original rough, is evidence of a process in which every decision was made by hand and was permanent: no two old mine diamonds are alike. It is precisely this quality that distinguishes it from anything produced after the introduction of mechanics and mathematical standards. This stone cannot be replicated, its attributes exceptional.

Designed as a medal featuring an onyx plaque with bald eagle crest, set with cabochon and buff-top calibrécut citrines and sapphires, accented by round diamonds, suspended from a similarly-set ribbon motif, signed Bvlgari; circa 1976.
The 1970s marked a period of international expansion for Bulgari as the house sought to broaden its clientele, opening its New York boutique at the Pierre Hotel in 1972 as the first of several locations abroad. Among the
diverse sources of inspiration the firm embraced during this decade, American imagery played a prominent role, most notably in its bold “Starsand-Stripes” jewels, created to engage a growing U.S. audience. Acquired at a Bulgari-hosted festivity in 1976 to mark America’s Bicentennial, the present brooch similarly celebrates patriotism with the American bald eagle, strikingly rendered in gold and onyx with sapphire and citrine stripes. Now offered ahead of the nation’s 250th anniversary, it is a compelling tribute to civic pride as conceived through the lens of sophisticated Italian style.

AQUAMARINE AND DIAMOND
SAUTOIR
Suspending a modified shield-shaped aquamarine, accented by single-, rosecut and round diamonds, the chain composed of geometric links set with single-, rose-cut and round diamonds, length approximately 24¼ inches, with a 3⅜ inch drop, signed Tiffany & Co., numbered; circa 1917-1919.
Accompanied by an IAJA letter.
An elegant example of Tiffany & Co.’s early Art Deco aesthetic, this aquamarine and diamond pendantnecklace reflects the firm’s position as the preeminent American jeweler, long synonymous with refinement and innovation in design. During the First World War, much of Tiffany’s manufacturing capacity was redirected toward the manufacture of surgical instruments and precision components
for guns and aircraft, resulting in a marked reduction in jewelry production. The period also saw platinum diverted to wartime use, prompting the use of platinum’s cousin palladium—an indicator that the present necklace was made during the war or shortly thereafter.
Tiffany’s pioneering role in the promotion of colored gemstones beyond the traditional repertoire, shaped in part by the influential gemologist Dr. George Frederick Kunz, is evident in the present piece. Introduced into Tiffany’s jewelry in the 1880s, aquamarine became one of the house’s most enduringly favored gemstones, its soft hue becoming closely associated with the celebrated “Tiffany blue.” Lot 52 represents the superlative workmanship that characterize Tiffany’s jewels from the early Art Deco period.

CITRINE, RUBY AND DIAMOND ‘BIRD ON A ROCK’ BROOCH
Set with a cushion-cut citrine, topped with a bird pavé-set with round diamonds, the eye set with a round ruby, signed Tiffany & Co., Schlumberger, one diamond missing.
Lot 55, a ‘Bird on a Rock’ brooch, exemplifies the whimsical yet highly sophisticated vision of Jean Schlumberger, one of Tiffany & Co.’s
most renowned designers. First conceived in 1965 for Rachel “Bunny” Mellon, the design reflects the close creative dialogue between designer and patron, drawing on their shared fascination with nature. The brooch features a diamond-set bird perched atop a vibrant colored gemstone, capturing Schlumberger’s imaginative interpretation of natural forms. Over time, the motif has become one of Tiffany’s most famed signatures, reinterpreted with a wide variety of gemstones and forms while retaining its distinctive sense of charm.
Another source of inspiration for Schlumberger was his family’s textile heritage in France, which informed his inventive approach to structure and design. This influence is evident in lot 56, a bracelet featuring his “X” motif, introduced in 1959 as part of the Sixteen Stone jewels. Derived from traditional cross-stitching, the motif translates a textile device into a distinctive design element that informed a number of later Tiffany collections.

VERDURA GOLD AND DIAMOND ‘WRAPPED HEART’ CLIP-BROOCH
Designed as a heart set with round diamonds, within a ribbon of gold ropetwist, signed Verdura. With signed box. The ‘Wrapped Heart’ brooch stands among Verdura’s most familiar motifs, first conceived in 1941 when actor Tyrone Power commissioned a ruby-set heart, “tied” in gold as a Christmas gift
for his wife, Annabella. Reinterpreted here entirely in diamonds and encased within a grid of gold ropetwist, the present example reflects the many variations the ‘Wrapped Heart’ has taken over the decades. While used here as a framing device, ropetwist also serves as a defining element in Verdura’s work, forming complete compositions such as the long chain in Lot 58, as well as appearing as a recurring accent across numerous designs.
Also counted among Verdura’s most successful design elements, the Maltese Cross emerged during his early collaboration with Coco Chanel, for whom he created a pair of cuffs adorned with the motif. Drawing on Byzantine mosaics, he carried their rich colors and patterns into fields of gem-set surfaces—an approach applied to later works, including the present brooch.

Accompanied by a copy of a David Webb Certificate of Authenticity dated April 12, 2017
Please note that the colored diamonds have not been tested for natural origin of color.
Since the introduction of David Webb’s first animal bracelets in 1957, creatures from the designer’s celebrated “kingdom” have remained among the House’s most longstanding and recognizable motifs. From zebras and frogs to leopards and cougars, Webb transformed the natural world into jewels of remarkable wit, glamour, and sculptural presence. Often distinguished by their exuberant use of color and texture, these creations incorporates carved coral, enamel, rock crystal, and vivid hardstone.
The present double leopard bracelet represents a particularly opulent interpretation of Webb’s celebrated menagerie. Entirely pavé-set with diamonds and accented by yellow and orange diamond spots, the bracelet balances ferocity with sophistication, its opposing felines rendered with the bold dimensionality and unmistakable glamour that characterize Webb’s work. Both playful and commanding, the design reflects the enduring appeal of the House’s animal jewels, which continue to captivate collectors nearly seven decades after their debut.

DIAMOND BROOCH
Featuring a line of old European-, old mine-cut and pear-shaped diamonds, signed Dreicer & Co.; circa 1911. With signed and fitted box.
$ 8,000-12,000
At the turn of the twentieth century, Dreicer & Co. stood among the foremost jewelers in America, renowned for handling some of the era’s most exceptional diamonds and pearls. Founded in New York by Jacob and Gittel Dreicer following their arrival from Europe in 1866, the firm quickly established a reputation for uncompromising quality and connoisseurship, attracting an elite clientele during the height of the Gilded Age. Though less widely recognized today than some of their contemporaries, Dreicer & Co. was once regarded on par with the great international houses, their Fifth Avenue salons synonymous with rarity, discernment and discretion.
The present jewels exemplify the sophisticated restraint that distinguished Dreicer’s designs. A brooch composed as a simple line of old European-cut diamonds demonstrates the firm’s confidence in the intrinsic beauty of exceptional stones, while the emerald and diamond bracelet reflects the geometric elegance and technical refinement associated with early twentieth-century platinum work. Its pierced openwork design achieves a remarkable sense of lightness and fluidity, balancing architectural precision with delicacy. As signed jewels by Dreicer & Co. appear only infrequently on the market, these pieces represent rare survivals from one of America’s most important early jewelry houses.

OSCAR HEYMAN & BROTHERS
PAIR OF DIAMOND AND ENAMEL EARCLIPS
Designed as gardenias pavé set with round diamonds, the leaves applied with green enamel, maker’s mark for Oscar Heyman & Brothers, numbered.
Founded by two brothers from Eastern Europe with an American dream, Oscar Heyman & Brothers was established in New York in 1912. Renowned for
their exceptional craftsmanship and meticulous attention to detail, the firm earned the sobriquet “the jeweler’s jeweler,” producing pieces of the highest quality for both private clientele and several leading maisons. Their position among the foremost American jewelry houses was firmly established by 1939, when they manufactured jewels for four of the five retailers featured at the New York World’s Fair.
It was during this period that the house introduced its famed ‘Gardenia.’ While florals have long served as a source of inspiration in jewelry, Oscar Heyman’s interpretation is distinguished by its remarkable naturalism and technical precision. Here, sculptural petals are finely set with diamonds, while the waxy enameled leaves create a convincing sense of depth and lifelike form— qualities that have ensured the design’s continued production through the present day.

SAPPHIRE AND DIAMOND
PENDANT-BROOCH
Of foliate design, featuring a pearshaped sapphire weighing 13.85 carats and set with old Europeancut diamonds, signed Marcus & Co.; circa 1900.
Accompanied by AGL report no. 1156611 dated May 14, 2026 stating that the sapphire is of Burmese origin, with no indications of heating.
Founded in New York in the 1890s by brothers William, George and Hermann Marcus, sons of a German émigré jeweler, Marcus & Co. grew from a family deeply rooted in the jewelry trade. Having trained under their father and within the network of Europeantrained craftsmen working in New York at the close of the nineteenth century, the brothers brought continental techniques and sensibilities to an emerging American luxury market eager to establish its own artistic identity. The firm quickly became one of the leading jewelers of the period, admired
for designs that balanced European elegance with a lighter, more fluid sensibility distinctly its own.
The present brooch captures these qualities beautifully. A vividly saturated pear-shaped sapphire is framed by scrolling diamond-set acanthus leaves, their curling forms giving the jewel a sense of movement and vitality.
Characteristic of Marcus & Co. at its best, the design achieves richness without heaviness, allowing the sapphire’s color to remain the focal point.

RAYMOND YARD
RUBY AND DIAMOND BRACELET
Composed of articulated geometric panels set with lines of baguette and square-cut rubies, surrounded and accented by variously cut diamonds, length approximately 6⅞ inches, signed Yard; circa 1935
Beginning his career at Marcus & Co., Raymond C. Yard earned the trust of America’s great collecting families not
only through his eye, but through his character. Known for his generosity, warmth and unwavering integrity, Yard formed lasting relationships with patrons such as the Rockefellers and Flaglers, many of whom followed him when he opened his own house in 1922. What Yard carried with him was more than technical mastery; it was a deeply held belief that jewelry should possess harmony in every detail. His relentless pursuit of balance and precision is vividly present in lot 65, where a ribbon of finely
matched rubies glows with remarkable saturation and life. Even the hidden architecture of a jewel commanded his attention — clasps, galleries and reverse surfaces finished with the same care as the stones themselves. Though often associated with jewels of tasteful restraint, the present bracelet demonstrates Yard’s ability to create jewels that are at once disciplined in design and undeniably striking.
$ 70,000-100,000
PROPERTY FROM AN ESTATE HARRY WINSTON
EXCEPTIONAL DIAMONDNECKLACE BRACELET COMBINATION
Composed of graduated pairs of round diamonds alternating with marquise-shaped diamond clusters, length approximately 15½ inches, detachable into four sections measuring approximately 6¾, 3½ , 3⅜, and 2 inches for wear as two bracelets or a necklace of varying length, maker’s marks for François Tavernier; circa 1960s. With signed box.
The genius of Harry Winston design lies not in overt complexity or fussy embellishment, but in the discipline of yielding, entirely, to the diamond. Central to this philosophy is the celebrated Winston cluster, in which the jewel’s form is dictated by the stones themselves. That such stones, particularly when they are as substantial as those in lot 66, can be supported by metalwork scarcely seen is a measure of the technical mastery behind the design.
In the present necklace, a series of delicate trefoil clusters of marquise diamonds support substantial pairs of round diamonds, suspended with the barest visible means of support. The effect is all the more striking given the necklace’s total diamond weight of more than 120 carats. Equally noteworthy is the prominence of round diamonds, as the Winston Cluster often favors marquiseand pear-shaped stones, making this necklace a particularly noteworthy expression of the House’s design.

Behind this collection is one man’s attainment of the American Dream and the grace he showed another struggling to achieve his own.
Romauldo DeChicchis emigrated as a child to the United States from Italy in 1907. A highly successful geologist, he moved to Texas to work in the oil industry where he met and married the consignor’s aunt, Mildred, in 1935. The consignor’s father, TJ, was the youngest of ten children who, from an early age, enjoyed the double-edged escape of a drink. In need of direction, he served in the military for four years before returning to Texas to become a roughneck. The idea of a ‘roughneck’ has become romanticized in American culture, but it’s a life of physically taxing days, often followed by booze-fueled
nights. For TJ, these nights could turn into days lost to both him and his family. Wishing to remove his brother-in-law from this aimless cycle, Romauldo hired TJ and taught him about the oil business beyond the rigs. TJ occasionally fell into old habits, but Romauldo never gave up on him. It was this fatherly patience that allowed TJ to become a very successful and respected businessman in his own right.
Romauldo took great pride in bestowing jewels upon Mildred. The pink and blue diamond earclips, ring and pendant were created by Linz Brothers, once one of the oldest and most prestigious jewelry firms in Texas. The jewels were inherited by TJ and his wife and subsequently passed down to the consignor.

LITERATURE
Fabienne Falluel, Van Cleef & Arpels, Paris, 1992, page 134 for an illustration of the design drawing for a similar clipbrooch, dated to the 1940s.
When Van Cleef & Arpels first introduced its ballerina brooches in the early 1940s, the world was in the grip of war — and Louis Arpels, a devoted patron of ballet, saw in dance exactly the kind of beauty and escape he wished his jewels to embody. Developed in collaboration between designer Maurice Duvalet and John Rubel, the ballerinas captured a sense of grace and optimism at a moment of profound uncertainty. Each figure was conceived as an individual character, depicted in varying poses, gestures, and costumes, their animated forms lending the jewels an unmistakable sense of personality and movement.
Though Van Cleef & Arpels and John Rubel parted ways in the mid-1940s, both houses continued to produce
ballerina brooches independently. Van Cleef & Arpels refined the ballerina into one of the House’s most longstanding and beloved themes, while Rubel Frères continued to create his own interpretations until closing their doors in 1950. Produced in limited quantities by both Van Cleef & Arpels and Rubel Frères, ‘Ballerina’ jewels have become increasingly elusive; the present group, lots 115–118, therefore offers a particularly rare opportunity to encounter such a troupe together in a single sale. Though small in scale— particularly the delightfully petite dancers of lot 117—they are immense in personality, each figure animated by its own distinctive charm.

Estimate upon request
Combining a mesmerizing blue hue with the brilliance unique to diamonds, blue diamonds, among the rarest gem materials on earth, elicit a passion among collectors that can verge on obsession. Global fascination with blue diamonds can arguably be traced back to 1668, when the explorer and merchant Jean-Baptiste Tavernier sold a 112-carat stone to King Louis XIV, who later had it recut to 67 carats and named it the French Blue; after its disappearance during the French Revolution, it remained unaccounted for until 1839, when it is believed to have reemerged, further recut to 45.52 carats, and was acquired by the Hope family. It would become, and remains, the most famous blue diamond in the world: the Hope Diamond. Historically, blue diamonds were first discovered in India, with Brazil later yielding occasional examples; today, they are primarily mined in South Africa. Their production remains exceedingly limited, as the conditions required for their formation are rarely met in nature. Unlike the vast majority of diamonds, blue diamonds are free from nitrogen and owe their distinctive color to trace amounts of boron. Recent research suggests that they form far deeper within the earth’s mantle than other diamonds, originating as deep as 400 to 600 kilometers below the surface—considerably greater than the 150 to 200 kilometers typical for nearcolorless stones.
The extraordinary conditions required for the formation of blue diamonds account for their exceptional rarity. The Gemological Institute of America estimates that only 0.3% of colored diamonds submitted to its laboratory are predominantly blue. Within this already rare category, stones exhibiting Fancy Intense saturation, coupled with unmodified color are particularly scarce. In most cases, blue diamonds display a modifying gray hue – even the legendary Hope Diamond has a grayish modifier. Against this context, the present diamond’s pure Fancy Intense Blue color distinguishes it as a rare and significant example.
As an outstanding unmounted stone, this diamond presents an ideal opportunity to create a unique jewel tailored to fulfill its future owner’s dreams. Whether as a magnificent ring or a superb pendant, this gem can become the focus of a customized, masterfully designed and crafted piece of jewelry. If requested, Sotheby’s Bespoke would be honored to have the opportunity to guide the winning bidder through the design process up to the delivery of a completed masterpiece.

The reserve is generally set at a percentage of the low estimate and will not exceed the low estimate of the lot. If any lots in the catalogue are offered without reserve, such lots will be designated by a box (□). If every lot in a catalogue is offered without a reserve, the Conditions of Business for Buyers will so state and this symbol will not be used for each lot.
○ Guaranteed Property
The seller of lots with this symbol has been guaranteed a minimum price from one auction or a series of auctions. This guarantee may be provided by Sotheby’s or jointly by Sotheby’s and a third party. Sotheby’s and any third parties providing a guarantee jointly with Sotheby’s benefit financially if a guaranteed lot is sold successfully and may incur a loss if the sale is not successful.

From time to time, a Sotheby’s

If the irrevocable bidder is the successful bidder, any contingent fee, fixed fee or both (as applicable) for providing the irrevocable bid may be netted against the irrevocable bidder’s obligation to pay the full purchase price for the lot and the purchase price reported for the lot will be net of any such fees. From time to time, Sotheby’s may enter into irrevocable bid agreements that cover multiple lots. In such instances, the compensation Sotheby’s will pay the irrevocable bidder is allocated to the lots for which the irrevocable bidder is not the successful purchaser. Under such circumstances, the total compensation to the irrevocable bidder will not exceed the total buyer’s premium and other amounts paid to Sotheby’s in respect of any lots for which the irrevocable bidder is not the successful bidder. If this auction has a printed catalogue, a PDF catalogue or both and the irrevocable bid is not secured until after such catalogue is finalized or if there is no printed catalogue or PDF catalogue and the irrevocable bid is not secured until after the digital catalogue is initially available for viewing, then Sotheby’s will notify bidders that there is an irrevocable bid on the lot by one or more of the following means: the lot’s specific webpage will be updated to include the irrevocable bid symbol, a notice will be added to the Sotheby’s webpage for the auction, or a pre-sale or pre-lot announcement will be made indicating that there is an irrevocable bid on the lot.

In addition, from time to time, an irrevocable bidder may have knowledge of the amount of a guarantee. If the irrevocable bidder is advising anyone with respect to the lot, Sotheby’s requires the irrevocable bidder to disclose his or her financial interest in the lot.

The top color grades, D, E, F, for a diamond is when it looks colorless against a white background.
In near colorless diamonds, G, H, I, there is a slight trace of color which will not be apparent to the untrained eye. Stones 0.50Ct or less will look colorless
Diamonds graded J, K, L, will have notable traces of color. Small stones in this range will ’face up‘ colorless when mounted but larger stones will be tinted.
Diamonds graded M-Z will display a yellowish tint even to the untrained eye.
Z+ color grade indicates that the diamond is of fancy color and therefore fall into a different price bracket.
