This magnificent 10.15-carat Blue Zircon is a rare treasure from the famous mines of Ratanakiri, Cambodia. While Blue Zircon is the traditional birthstone for December, finding a gem of this magnitude (over 10 carats) with such saturation is exceptionally difficult.
Not to be confused with synthetic Cubic Zirconia, this is a Natural Zircon—one of the oldest minerals on Earth. It is famous for its High Dispersion (fire), which rivals that of a diamond. This specific stone displays an intense, electric "Teal Blue" color that shifts between ocean blue and vivid green depending on the lighting.
The expert Cushion Cut maximizes its natural brilliance, creating a "hall of mirrors" effect due to Zircon's unique double refraction. A true collector's piece that will make a spectacular statement cocktail ring or pendant.
