20.75 ct Blue Zircon - Oval

At 20.75 carats, this zircon from Cambodia carries its blue color through an oval cut, measuring 17.1 x 12.8 x 10.1 mm.

Zircon is the natural mineral often confused by name with a synthetic imitation; the real gem has fire and brilliance close to diamond. It is heated, a standard and stable treatment that we disclose plainly, the way an honest seller should.

Few stones reach this combination of size and quality, and fewer still come to market. We will tell you everything we know about it before you decide.
