Zircon is a relatively hard stone with a hardness of 7.5. Its high specific gravity 4 – 4.73, make it easy to identify and few gemstones are as dense. Experienced buyers can identify zircons by heft alone. Because it has such a high refractive index, zircon can be exceptionally brilliant.
Natural zircon is often confused with cubic zirconia, a laboratory-grown diamond stimulant. Natural zircon and cubic zirconia are totally unrelated, zircon is a naturally occurring gemstone while cubic zirconia is a synthetic.
Zircon is mined in Cambodia, Sri Lanka, Thailand, Myanmar, Australia, Vietnam, Tanzania, and Madagascar. The best blue zircons are from Cambodia and they have been heated to produce that color. The wide variety of colours of zircon, its rarity, and its relatively low cost make it a popular collector's stone.
Zircon is a stone of purity and innocence. It balances the emotions and enhances self esteem and unity. Was used as an amulet by travellers to protect against accident and injury on the journey. It was also used to stop the wearer from being stuck by lightening. Hindu poets tell of the Kalpa Tree, the ultimate gift to the gods, which was a glowing tree covered with gemstone fruit with leaves of zircon. Zircon has long had a supporting role to more well-known gemstones, often stepping in as an understudy when they were unavailable. In the middle ages, zircon was said to aid sleep, bring prosperity, and promote honor and wisdom in its owner. The name probably comes from the Persian word zargun which means gold-colored, although zircon comes in a wide range of different colors.
