Schlumberger Paris Flame

Jewelry designer Jean Schlumberger once said that he strived to “make everything look as if it were growing, uneven, at random, organic, in motion.” His jewels interpreted the vitality of the natural world with lively designs that included a moonstone-topped jellyfish brooch with sapphire tentacles exuding a watery shimmer and a ring encrusted with a burst of diamonds that “bloomed” like a flower bud.

A self-taught jeweler, Schlumberger’s mastery of color as well as his expertise as a draftsman brought his fantastic ideas to life. Born to a leading textile manufacturing family in Alsace, France, Schlumberger took to drawing as a child and showed promise as an artist, but his parents instead sent him to study banking in Berlin in the 1930s. Uninspired, he departed for Paris and began creating buttons for Italian fashion designer Elsa Schiaparelli, who also commissioned him for costume jewelry.

One of Schlumberger’s early pieces — a cigarette lighter in the form of a fish whose head opened to reveal the flame — demonstrated his skill for capturing the vivacity of nature in precious metal. The designer’s imaginative jewelry was in contrast to popular geometric lines of Art Deco, an independent vision he affirmed in the extravagant 1941 Trophée de Vaillance brooch created for fashion editor Diana Vreeland. An extravagant confection of diamonds, amethyst, rubies and gold, the brooch featured gemstones adorning an intricate intersection of tiny spears and a breastplate over a glittering shield.

After serving in the French army and the Free French forces during World War II — and surviving the Battle of Dunkirk — Schlumberger left war-torn Europe for New York and in 1946 established a jewelry salon with Nicolas Bongard. There, his vibrant work caught the eye of Tiffany & Co. After joining the American luxury jewelry house in 1956, he soon had his own studio on the mezzanine of Tiffany’s Fifth Avenue store that he accessed by a private elevator. In his workshop, Schlumberger used a rainbow of gemstones, gold and diamonds to create some of the company’s most beguiling designs.

From striking earrings shaped like soaring wings to diamond birds perched on glittering gemstones, each of Schlumberger’s Tiffany designs dazzled. His supporters included Bunny Mellon, whose love for horticulture inspired commissions such as the Jasmine necklace with diamond blossoms flowering from a garland of colored sapphires, and Jacqueline Kennedy, who wore his Croisillon bracelets so often they became known as “Jackie bracelets.” Schlumberger retired from Tiffany in the late 1970s, but decades after his designs were introduced many of his popular pieces remain in production.

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.
