4.20 Carat Natural Sky Blue Zircon
Located in Hua Hin, TH
A beautiful sparkling Cushion-Cut 'Sky-Blue' Zircon from Ratanakiri, Cambodia.
Rare sparkling Blue Zircon is only found at one place in the world at Ratanakiri province in Northeast Cambodia. Blue Zircon in this vivid blue color is very rare indeed. We cherry pick the stones at the mine in Cambodia and only 1% of all Blue Zircon mined have top quality blue color. A miner may find only a handful of these coveted crystals in a year, These Zircons have a color not normally seen in the main market and are extremely rare and out of a pedigree that very few people will ever own or even see. We are specialist in Investment Blue Zircon and have office in Ratanakiri there we can source all the best stones direct from the miners.
Blue zircon is a beautiful and unique gemstone that has been prized for centuries for its striking color and brilliance. In fact Blue Zircon has a higher refractive index than sapphire and ruby. Blue Zircon also has a impressive fire, with a dispersion nearly as high as the diamond's.
