The spectacular creations of David Rosenberg are legendary in the world of jewelry. Nicknamed the “Ice Man” for his diamond expertise, Rosenberg is a Florida-based jeweler and designer widely known for his radiant gemstone confections. His company, Rosenberg Diamonds & Co., creates everything from engagement rings and bridal rings to lavish drop earrings and tennis bracelets. Rosenberg has even been commissioned to design jewelry for Queen Elizabeth II.

Rosenberg spent his childhood in Tel Aviv, where he first discovered his love and passion for diamonds. A self-taught diamond expert, he later founded Rosenberg Diamonds & Co. in 1981 and opened an upscale boutique in Boca Raton, Florida.

Over a career spanning more than two decades, Rosenberg has earned a reputation for sourcing rare fancy-colored diamonds. Accounting for just 1 percent of all diamonds, these marvels of nature are exceedingly rare and gorgeously complex. The value of colored diamonds increases exponentially with the saturation of the color. Large, richly hued stones are exceptionally rare and so can fetch millions of dollars. Rosenberg sources his diamonds from mines in Russia, Botswana and the Democratic Republic of Congo. He is also one of the few diamantaires carrying rare argyle pink diamonds from Western Australia. He then transforms these exclusive diamonds into covetable one-of-a-kind pieces of jewelry for his esteemed clientele.

Rosenberg is a member of the World Federation of Diamond Bourses and the president of the Diamond Bourse of Southeast United States. He is also a former director of the Natural Color Diamond Association. He continues to travel the globe, searching for the rarest diamonds and staying on top of trends in the jewelry world. According to Rosenberg, some of today’s most popular diamond cuts are cushions, radiants and ovals.
