The British jeweler Sir Laurence Graff (b. 1938) became utterly mesmerized by diamonds when he undertook his first apprenticeship at age 15 in London’s Hatton Garden jewelry district. It wasn't long before he established his now-celebrated eponymous brand, which produces engagement rings, necklaces, rings, earrings, stand-alone jewels, watches and more — all entirely in-house.
Graff had enrolled in classes at Central School of Arts and Crafts, and while he initially showed promise and was highly regarded, the shop owner, Mr. Schindler — who had his apprentice scrubbing floors and toilets — soon changed his tune, deeming him subpar. Undeterred, Graff learned to repair rings and designed small jewels at a humble workbench in his bedroom. He opened a 24-hour ring-repair service with a business partner and, in 1960, founded his luxury house. Two retail locations followed in London in 1962. Graff would go on to become one of the finest diamantaires in the world and was appointed an OBE in 2013 by Queen Elizabeth for his services to the jewelry industry.
Graff is known for handling some of the most famous diamonds in the world, including the Windsor Yellows, the Paragon, the Lesotho Promise and the Wittelsbach-Graff. He also purchased the 302.37-carat Graff Lesedi La Rona, which, at the time, was the largest diamond ever graded by the Gemological Institute of America. The GIA certified the diamond — then the second-largest gem-quality rough diamond on record — as being of highest color and highest clarity. Lucara Diamond Corporation workers discovered the 1,109-carat rough diamond in 2015 at the Karowe mine in Botswana, and after Graff purchased the diamond in 2017, his gemologists and craftsmen spent more than 18 months polishing its final facets.
While many jewels, such as the Graff Lesedi La Rona, remain in Graff’s collection, he does sell extremely high-quality stand-alone jewels. Gems in his showrooms can reportedly fetch hundreds of thousands of dollars on average. Although these stones are perhaps slightly out of the budget of a typical Graff jewelry client, the house does work with more reasonably priced, but no less exceptional gems for its collections.
Naturally, diamonds feature prominently in Graff jewelry, which is known for being more avant-garde than traditional, although Graff does create classic engagement rings, too. The jeweler’s ready-to-wear collections integrate naturalistic motifs like butterflies, bows and sunbursts, as well as striking silhouettes like the crisscrossed Kiss, the clustered Threads and the swirling Inspired by Twombly line, which pays homage to the work of American painter and sculptor Cy Twombly. And while diamonds are the main focus for Graff, his jewelry occasionally features other precious and semiprecious stones.

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.
