Art Deco golden zircon and diamond ring. Set to centre with one rectangular emerald-cut golden zircon in an open back claw setting with an approximate weight of 18.00 carats, flanked by eight round old cut diamonds in open back grain settings with an approximate combined weight of 0.24 carats, all to a bold angular design featuring polished borders, a decoratively pierced geometric gallery and open backholing, leading to raised shoulders and flowing through to a solid shank. Tested white gold and platinum, circa 1935.

The name zircon derives from the Arabic words “Zar”, meaning gold, and “Zum” meaning color. Geologically dating as far back as 4 billion years, Zircons were used in Greece and Italy as far back as the 6th Century AD. After faceting began in the 14th Century, colourless zircons were even sold as diamonds simulants!

While blue is the most well-known color of zircon, it actually comes in a wide range of colors, including red, orange, yellow, green, brown, and colorless. Ceylon and Burma are sources of gem zircon, which are surface mined from river gravels.

Rough Zircon is one of the key minerals used by geologists in geochronology (the study of the geological history of the earth).

This ring is in excellent condition.
