Explore Collection
Zurich stands as one of the most financially significant and privately serious luxury markets in the entire world — the banking and financial capital of Switzerland and home to some of the most sophisticated private investors, family offices, and serious collectors anywhere on earth. Alongside Geneva, Zurich represents the pinnacle of European private wealth management — a city where the world’s most significant fortunes are quietly administered, where investment decisions of the highest magnitude are made with complete discretion, and where the standard for quality, rarity, and provenance in every acquisition — including the finest natural diamonds — admits absolutely no compromise.
At this level of the market, natural Fancy Vivid and Fancy Intense colored diamonds, D Flawless white diamonds, and important stones of significant carat weight are not found through conventional retail channels or luxury shopping streets — they are sourced privately, evaluated by specialists, and presented to buyers whose understanding of value, rarity, and long term significance is among the most refined anywhere in the world. Rosenberg Diamonds & Co., based in Boca Raton, Florida, serves the Zurich market with private access to the rarest and most important diamonds in the world — natural GIA certified Fancy Vivid Blue, Fancy Intense Blue, Fancy Vivid Pink, Fancy Intense Pink, Fancy Vivid Yellow, Fancy Intense Yellow, Fancy Vivid Green, Fancy Vivid Orange, and Fancy Red diamonds, alongside D Flawless white diamonds and important stones of 10, 15, 20, 25, and 30 carats or more. Every stone we present is 100% natural, untreated, and accompanied by full GIA certification. Our Zurich clients are serious collectors, private banking clients, family offices, and investors who demand the finest stones the market has to offer — and who trust Rosenberg Diamonds & Co. to deliver them with the expertise, discretion, and access their acquisitions demand.
