New York-based David Birnbaum and his extensive network of contacts scour the globe for the most incredible rocks.‌ His company Rare 1 are specialists in top-of-the-line diamonds, rubies, emeralds, sapphires and pearls, selling to 'VIP clientele types.'‌ Birnbaum deals with an elite slice of the market.‌ If you're in the market for some $100 million bling, a Fifth Avenue diamond dealer-to-the-stars claims to have the rarest 'super gems' on Earth.‌ From the newly trendy $1 million 'Power Rings' popular on Wall Street to 100 carat diamonds for the mega-rich, David Birnbaum and his extensive network of contacts scour the globe for the most incredible rocks. His company Rare 1, located above New York’s Fifth Avenue, are specialists in top-of-the-line goods – diamonds, rubies, emeralds, sapphires and pearls, selling to ‘VIP clientele types.’‌ Fifth Avenue brands such as De Beers and Cartier sell their sparklers to the top 2 per cent of the population, on average.‌ But Birnbaum deals with an even more elite slice of the market – the top 0.1 per cent only, otherwise known as the mega, mega rich.‌ Fortunately for Birnbaum, these people are heads-of-state or genuine Hollywood A-listers leading luxurious lifestyles with deep pockets and money to burn.‌ Birnbaum, who lives in New York, said: 'What we do lies on the border between mission impossible and mission possible – we have to keep finding ever-more unique and ever-more special gems all the time.'‌ 'Our primary clientele are the top 1/10 of 1 per cent of the global financial elite but over the years we have developed a dynamic and loyal client group ranging from young bankers to heads-ofstate.'‌ REPRINTED FROM METROPOLITAN MAGAZINE FEBRUARY 2021‌

Interview‌

Master of the Game‌

A conversation with David Birnbaum, The Rare & Extraordinary Private Jeweler‌

By Chase Backer, Editor of Metropolitan Magazine‌ REPRINTED FROM METROPOLITAN MAGAZINE FEBRUARY 2021‌

CHASE Let me ask you a question. How do you create your pieces? Do you see, in your mind, a piece that you want to create, and then you go find the jewels, or do you find an outstanding jewel and then decide that you want to create a piece around it?‌

DAVID‌ Frankly, it caught us by surprise, as well. I presume it is because we do a big and steady business in important top labcertified diamonds, rubies, and related – where the $ per sale can add-up quickly.

Plus, periodically, we sell $10M+ pieces.‌

DAVID‌ So, first, you need to ‘read the market’; you cannot create a specific piece without a good feel for where the ‘strike zone’ for the market is; Once you have radar-lock on the market, you can let the creative juices roll – and design a unique and exquisite piece.‌

CHASE So your formula has somehow allowed you to trump the international brand Fifth Avenue Retail Jewelers – at their own game? You somehow have managed to invent a better mousetrap – apex quality at rock-bottom pricing – with World Class styling in the mix; perhaps more CEOs and Private Equity partners per month buying high-ticket items from you – than from any of the other top jewelers in NY; and, it turns out, greater selection than firms 3x your size; how is this at all even possible?‌

CHASE How do you stay ahead of the competition?‌ DAVID‌ Respectfully, our David Birnbaum / Rare 1 ‘package’ cannot even be approached. We respect our (alleged) competition, however illustrious they may be – but, with due respect, they cannot touch us.‌

DAVID‌ All the components are interrelated; that is what my clients are entitled to;‌ I am personally able to handle 75%+ of the deals; I grew up in a diamond family – although that dynamic predecessor firm focused on buying the rough gems (globally) – and selling wholesale (globally) to those same Fifth Avenue international brands; I navigated that prominent De Beers SightHolder from Andor & David Birnbaum, Inc. to quite significant global‌

CHASE Platinum Card advised you that you had the highest average sale in the world’s – of any jewel company. How do you explain that?‌

DAVID BIRNBAUM | RARE 1‌

CHASE How has the pandemic affected your firm?‌

growth – alongside my formidable late father – Andor J. Birnbaum – who focused pretty much exclusively on the rough diamond buying aspect.‌

DAVID‌ Well, the pandemic per se, is horrendous, of course; it is akin to a biblical plague; But, life goes on; the unintended consequence of the pandemic has been the serial and ongoing off-the-charts trillion-dollar US Government stimulus programs; This ongoing surreal government endeavor has super-charged the specter of off-the-charts hyper-inflation; but, which two or three items globally will actually hold value without roller-coaster valuations? It turns out, the list is very short – and very narrow: TOP GEMS: toplab-certified diamond, rubies, sapphires and emeralds; thus, rumor-has-it, the grandiose Federal Reserve stimulus programs have catalyzed a ‘perfect storm’ for our specialist firm – and for select gem valuations. And as they say, ‘we know the deal.’‌

In many cases, the gem you buy from me currently is, indeed, cut from a rough diamond straight from the mine in Russia or Botswana; it turns out that I am quite wellversed and quite well plugged-in.

Respectfully, no one can match our global sourcing; and unlike some of the international brand Fifth Avenue firms, we have no covenants precluding us from seeing at low margins; we are, indeed, fierce competitors; we have significant important repeat business from a very fine clientele – from talented millennials – thus major American businessmen / executives / financiers – thru Royal Houses in the Gulf.

On the design-front, my late mother was a fine career artist with a large studio in our house; design permeated the air and the buzz is that allegedly I have a strong flair for the nuances of color, design and design trends; I am thus able to ride herd more adroitly over our talented and awardwinning designers. On another front, as fate would have it, in 1974 I completed my Master’s thesis – at that well-known Boston business grad school – on diamond investment – and I have a strong ‘record, focus & feel’ for that important dimension; thus, several interrelated key components have conspired to give us a significant competitive advantage from the get-go; and, finally, our core overhead – while classy – is relatively lean. And, finally, again, we have been lucky.‌

CHASE Basically gemstones as an investment – via Solitaire rings – or studs?

That’s the wave of the future?‌ DAVID‌It’s not the future, it’s already here.‌ CHASE And do you have situations – past few months – where clients commission you to buy a million dollars+ of, say, D Color round diamonds – or Pigeon’s Blood rubies?‌ DAVID‌YES, to each of those questions.‌ CHASE And who holds the gems postpurchase?‌

CHASE Would you say that the financial elite, in general, gravitate to your unique firm?

DAVID‌In about half the cases, we are asked to do so.‌ CHASE To act as custodian – for potential inter-generational handling of the gems?‌

DAVID‌ The financial elite, the millennial elite, and the young Royal Family elite [from the Gulf]. Elite gems and value – for an elite group. When we get a call, we concentrate very, very carefully – and endeavor to optimally implement ‘our part of the equation’.‌

DAVID‌ In cases where we are asked to hold the gems in custody, in about half the cases it is, indeed, for inter-generational handling.‌ Chase Backer‌ Publisher, Metropolitan/25A‌ REPRINTED FROM METROPOLITAN MAGAZINE FEBRUARY 2021‌

NOTE EDITOR’S

REPRINTED FROM METROPOLITAN MAGAZINE FEBRUARY 2021‌

New York City is frigid and snow-covered outside right now but when you want to talk about ice you need to speak with New York City’s most exclusive private jeweler, David Birnbaum of Rare 1. A classy and worldrenowned King of Rare Gems, David Birnbaum’s extraordinary and rare diamonds, rubies, emeralds, and sapphires dazzle and inspire, energize, and transform. They are powerful, timeless, and truly the stuff that dreams are made of. It was no surprise to me that David Birnbaum, an iconoclast thought leader who enjoys discussing metaphysics and Potentialism theory with Deepak Chopra in his spare time, and our Publisher Chase Backer would develop an immediate rapport. Both are men of vision who operate at the very highest rung of their chosen professions and are trusted friends to the world’s most successful and powerful individuals, families and businesses.‌ Adam Kluger‌ Editor in Chief, Metropolitan Magazine/25A‌

The Divine‌

39‌

In the rarefied world of the inconceivably rich, the myth and legend of flawless stones comes to life thanks to at least one contemporary private jeweler in New York – Rare 1’s‌ ‌by David Birnbaum. Typical jewelry houses like‌ ‌Cartier and DeBeers‌ ‌cater to the top 2% of the population in luxury. David Birnbaum’s clients fall into the even more exclusive 0.1% of the mega-rich. David himself encapsules Rare 1's design niche as - "timeless design with a contemporary flair".‌ The company travels the world in search of only the purest D-grade diamonds, rubies, emeralds, and sapphires . Birnbaum's clients love the designs he creates as if they were made in a Parisian atelier. Some of the pieces he creates are contemporary in design while others seem to come from old Hollywood. From Art Deco influences to the most regal diamonds worn by movie stars of the Golden Age, they make the wearer feel like Elizabeth Taylor, who never borrowed, only bought.‌ ‌Rare 1‌ ‌marries opulent designs to the client's personal dreams to make wishes come true.‌ So exclusive that only a handful of people are allowed inside this sanctuary of brilliant perfection , and even fewer are the owners of these one-of-a-kind gems, whose names are kept strictly under wraps. Only rarely are movie stars and royalty photographed with their jewels traced back to Rare 1 , such as the engagement ring given by* *James Gandolfini to his wife, the jewels worn by Goldie Hawn to a premiere or gala, or those worn by former first lady Laura Bush alongside her husband George Bush. Birnbaum's latest creation - a 90carat, 16-diamond, D-grade bracelet worth $30 million - is absolutely spectacular. If your finances allow, make an appointment to see these one-of-akind pieces of sublime art up close!‌ original article‌

Eclipse Blossom‌ IN THE SHADOWS OF OPULENCE, WHERE MIDNIGHT WHISPERS TO THE STARS, AN OBSIDIAN BLOOM UNFURLS. THIS HANDCRAFTED ART DECO RING—BATHED IN THE COSMIC LUSTER OF BLACK DIAMONDS—IS A REBELLION AGAINST THE ORDINARY, A DARK SYMPHONY OF ELEGANCE AND EDGE. A FLOWER NOT OF GARDENS, BUT OF GALAXIES—CRAFTED FOR THE BOLD, WORN BY THE EXTRAORDINARY. ECLIPSE BLOSSOM IS NOT JUST A RING; IT IS A STATEMENT, A LEGEND, A FLEETING MOMENT OF NOIR BEAUTY CAPTURED FOREVER.‌
