OPAL

OPAL Opal is a stunning and unique gemstone known for its play-of-color, a phenomenon where it displays vibrant flashes of iridescent colors when viewed from different angles. The play-of-color is a result of the diffraction of light by tiny silica spheres within the opal's structure.

TYPES OF OPALS Precious Opal: This type of opal displays the characteristic play-of-color and is further classified into different varieties such as white opal, black opal, and crystal opal.

Fire Opal: While lacking the play-of-color, fire opals are known for their vivid body colors, ranging from yellow and orange to red.

COLORS AND PATTERNS: Opals come in a variety of colors, and their value is often determined by the intensity and variety of colors present in the play-of-color.

Common colors include blue, green, red, orange, and violet. The play-of-color can exhibit patterns like harlequin, pinfire, and floral.

Opals are formed from silica-rich solutions that fill voids or cracks in rocks. Over time, these solutions harden to form opal.

FORMATION

LOCATIONS

Australia is a major source of opals, with the famous Lightning Ridge producing black opals. Other significant sources include Ethiopia, Mexico, and Brazil.

Opals are relatively soft compared to other gemstones, so they require gentle care to avoid scratches and damage. They are sensitive to heat and should be protected from rapid temperature changes.

CARE

CONCLUSION Always purchase opals from reputable dealers who provide information about the stone's characteristics, origin, and treatment (if any). Opals can be particularly sensitive to changes in humidity, so proper storage is also important to maintain their beauty over time.
