Possessed of both a high refractive index and high dispersion, zircon is one of the few gems capable of rivaling diamond for brilliance and fire. As the birthstone for December, this oval-cut collector’s gem of superb quality displays a deeply saturated blue of the most desirable nature, surpassed only by its excellent transparency and luster. Long before scientists manufactured the first cubic zirconia gemstones, nature had already produced its own version—zircon. Only a few other gem materials equal the dispersive « fire » of zircon, diamond being one of them. In most zircons, the « fire » is often masked by a dark body color. That is not the case with this wearable and collectible stone. Zircons of more than 3 carats are exceedingly rare.
Weighing approximately 16.75 carats and measuring 16.0 x 11.5 x 8.5mm
