Art Deco zircon and diamond ring. Set with one central rectangular emerald-cut zircon in an open back claw setting with an approximate weight of 15.00 carats, flanked by raised tapered shoulders set with eighteen round eight cut diamonds in open back grain settings with an approximate total weight of 0.54 carats, to a geometric design with an openwork gallery, pierced backholing and flowing through to a D-shape shank. Tested platinum, circa 1930.

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.
