Zircon is considered to be a very brilliant stone because of its high refractive index. It is also very hard and well suited for a wide range of jewellery uses. An important identification mark for all Zircons, (except the green) is a strong double refraction easily seen under the loupe at the facet edges. Blue and Green are the most desirable Zircons. Zircon is said to aid sleep, bring prosperity, and promote honor and wisdom for its owner. It can be used as an amulet for travelers. It brings the wearer financial success and protection from being struck by lightning. In the symbolic Kalpa Tree of the Hindu religion, Green Zircon represents the tree’s foliage. Zircon is found in Cambodia, Sri Lanka, Thailand, Myanmar and Australia and is one the birthstones for the zodiac sign of Capricorn, with the other one being Turquoise.
