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.

Antique diamond rings, diamond tiaras and dazzling vintage diamond earrings are on the wish lists of every lover of fine jewelry. And diamonds and diamond jewelry are primarily associated with storybook engagements and red-carpet grand entrances — indeed, this ultra-cherished gemstone has a dramatic history on its hands.

From “A Diamond Is Forever” to “Diamonds Are a Girl’s Best Friend,” pop culture has ingrained in our minds that diamonds are the most desired, the most lasting and the most valuable gemstone. But what makes the diamond so special? Each stone — whether it’s rubies, sapphires or another stone — is unique and important in its own right. April babies might claim diamonds for themselves, but just about everyone wants this kind of sparkle in their lives!

There are several factors that set diamonds apart from other stones, and these points are important to our gem education.

Diamonds are minerals. They are made up of almost entirely of carbon (carbon comprises 99.95 percent; the remainder consists of various trace elements). Diamonds are the hardest gemstones, ranking number 10 on the Mohs Hardness Scale. Even its name, diamond, is rooted in the Greek adamas, or unconquerable. The only object that can scratch a diamond is another diamond. Diamonds are formed deep within the earth at very high temperatures (1,652–2,372 degrees Fahrenheit at depths between 90 and 120 miles beneath the earth’s surface) and are carried up by volcanic activity. Diamonds are quite rare, according to the Gemological Institute of America, and only 30 percent of all the diamonds mined in the world are gem quality.

In the 1950s, the Gemological Institute of America developed the 4Cs grading system to classify diamonds: clarity, color, cut and carat weight. Not all diamonds are created equal (there are diamonds, and then there are diamonds). The value of the diamond depends on the clarity (flawless diamonds are very rare but a diamond's value decreases if there are many blemishes or inclusions), color (the less color the higher the grade), cut (how the diamond’s facets catch the light, certain cuts of diamonds show off the stone better than others) and carat weight (the bigger, the better).

When you start shopping for a diamond engagement ring, always prioritize the cut, which plays the largest role in the diamond's beauty (taking the time to clean your diamond ring at least every six months or so plays a role in maintaining said beauty). And on 1stDibs, a range of buying guides can be found for those in the market for antique engagement rings, vintage engagement rings or Art Deco engagement rings.
