G: Art of a Jewel

 

Glenn Spiro’s unrelenting quest for superlative stones—and his unwillingness to settle for less than the best—started early. The East Londoner grew up in a working-class family and left school at 15 to work as a goldsmith’s apprentice at English Artworks, Cartier’s workshop in London. It was there he learned the art of the craft alongside master jewelers. With a propensity for unconventional and bold ideas, Spiro struck out on his own at just 22, opening a small workshop with his partner and friend, Robert Aylett, in London’s famed jewelry district. He worked at the bench and produced commissions from jewelry houses for several years, until the business was acquired.

 

Spiro describes himself as having been “rough around the edges” when he arrived in the United States in 1992. “I learned how to negotiate with clients and dealers with a certain finesse and charm, and I learned never to go more than 24 hours without responding to an email or call.”

 

By 2000, Spiro returned to Europe, setting up offices in London’s Mayfair district as well as in Geneva. From these locales, he created elaborate gemstone designs that were sold to some of the most prominent high-jewelry houses. During this period, he opted to remain behind the scenes, creating showstopping designs for other brands. Over time, however, private clients, acquaintances and friends would seek out Spiro for jewelry advice or to commission important pieces. Concurrently, he witnessed a shift in the luxury world: the ever-increasing emphasis on profit favored the creation of “safe” jewels with broad appeal, resulting in a lack of innovation. To be a great designer, boundaries must occasionally be pushed.

 

After designing for other houses for nearly 25 years, Spiro established his own house, G, in 2014, on Mayfair’s Bruton Street. He quickly established himself as an artist whose designs are at once contemporary and timeless, and always set with exceptional stones.

 

Lot 91, The Sienna Star, represents a culmination of Spiro’s oeuvre, embodying the relentless pursuit of the world’s finest gemstones with an artistically daring and innovative design. At over 73 carats, the diamond represents one of the largest Fancy Vivid Yellow diamonds to ever come to auction, and it is, in the GIA’s words, “a standout item in the extraordinary world of gemstones.” The ring itself adds a masterful aesthetic. With intricately set pave diamonds and a flexible shank, it complements the central diamond perfectly, creating a piece of truly wearable art.
