Blue zircon has been a popular stone since ancient times, and due to its blue hues, it is loved by collectors and merchants. The dispersion and brilliance of zircon are unique in the family of precious stones, they fascinate and envelop in mysticism, exerting a hypnotic effect.
Blue zircon is sometimes also called cambolite.
As the name suggests, blue zircon has an aquamarine color, with a greenish tinge when viewed from a certain angle. Zircons have a characteristic property known as double refraction. Carvers often have to orient the face of the stone along the optical axis; if the carver does not do this, the interior will look blurred due to the doubling of the image on the faces.
Zircon is found in igneous rocks all over the world. The largest sources of high-quality blue zircon are Thailand, Cambodia and Sri Lanka, which is not surprising since they are the main exporters of most precious stones.
Other countries where blue zircon can be found are Russia, Norway, Germany, Madagascar, and Brazil. However, these sources do not produce zircon of such high quality as in Southeast Asia.
