Harry Winston Cushion

Among the famed gemstones that Harry Winston (1896–1978) encountered over the course of his career was the Hope diamond, which he donated to the Smithsonian Institution in 1958. Today, Winston is regarded as the “King of Diamonds” and the “Jeweler to the Stars” as one of the first to recognize the branding power of lending glitzy earrings, necklaces and other fine jewelry for red-carpet events.

Winston’s father had immigrated to New York from Ukraine and ran a small jewelry shop where a young Harry learned about precious stones, enough, the story goes, to identify a real emerald in a heap of pawnshop jewelry at the age of 12. His early success involved turning that eye to estate sale collections that he transformed by freeing gemstones from dated ornamentation, giving them new cuts and modern settings. He opened Harry Winston Inc. in 1932, where he influenced 20th-century-jewelry trends by always elevating the stones rather than adding the lavish decorations that had pervaded jewelry in the 19th century.

The first of the celebrated diamonds to be purchased by Winston was the 726-carat uncut Jonker, acquired in 1935. Many others followed, including the 726.60-carat Vargas from Brazil which, in 1938, he tracked down across multiple continents after he read a brief newspaper notice about its discovery. The rarity and beauty of the gemstones he pursued and presented in his boutiques made the Winston brand synonymous with excellence.

Winston was also a pioneer of marketing as the first jeweler to dress an Academy Awards nominee when he loaned some diamond jewelry to Jennifer Jones for the 1944 Oscar ceremony. Winston was renowned for his eye for the finest of gemstones and the ability to design pieces in order to best flaunt their natural dazzle. He regularly showed off his collection in touring exhibitions, such as the 1949 “Court of Jewels,” which featured the Hope diamond. His storied past and long legacy is continued by the House of Harry Winston and its salons in Japan, the United Kingdom and elsewhere.

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.
