Sparkly & Rare: Important Diamonds in Alex Cooper’s December Gallery Auction

Diamond’s allure has endured centuries. By 100, AD, diamonds were regarded as objects of beauty and desire. The Roman philosopher and naturalist, Pliny the Elder, claimed, “Diamond is the most valuable, not only of precious stones, but of all things in this world.” The earliest known diamond engagement rings date back to the late 14thcentury. Hollywood jewelry icon Elizabeth Taylor’s love of diamonds is legendary. From her 29.4 carat emerald-cut diamond engagement ring from Mike Todd (which she affectionally called her “ice-skating rink”) to her 33.19 carat “Taylor-Burton” Asscher-cut diamond ring, Taylor knew the true wonders of the gemstone, famously declaring, “Big girls need big diamonds.”

Rare marvels of nature, diamonds formed deep in the earth well before the human fascination with them began. Predating the dinosaurs by 2.85 billion years, the oldest known diamonds, recovered from Canada’s Diavik and Ekati mines, have been determined to be 3.3-3.5 billion years old. In addition to their remarkable age, diamonds are incredibly tough, withstanding tremendous amounts of heat and pressure to make them the most durable and sparkly of all gemstones.

Lot 172 is an impressive antique ring centering a 3.20 carat old European-cut diamond surrounded by a halo of 16 additional round-cut diamonds. Old European cuts date to around the late 19th – early 20th century and feature high crowns, deep pavilions, and open culets—meaning that the bottom tip of the diamond has an extra circular facet that is visible through the diamond’s table. Most early old European diamonds were cut by hand before the introduction of mechanized cutting techniques, making each diamond truly unique.

Made fashionable in the late 1950s – 1960s by “jeweler to the stars” Harry Winston, the Classic Winston uses tapered baguettes to complement the elegant proportions of a pear-shape diamond. Along with its graceful pear and baguette-diamond design, the Lot 135a’s sturdy platinum setting is ideal for this timeless engagement ring to be passed down for generations.
