The Kalpa Tree was said to be the ultimate gift to the gods in Hindu poetry. This was a tree covered in gemstones, with leaves of Zircon.

Zircon has been thought to aid sleep, promote honor and wisdom, and bring prosperity. The Persian word “zargun” means gold-colored, and is whence the name ‘Zircon’ sprang.
Zircon is not to be confused with Cubic Zirconia, the laboratory-grown diamond imitation. Zircon is a beautiful natural gemstone available in a wide range of colors. The colorless variety, though, is popular for its brilliance and dispersion.

Zircon is also available in green, dark red, yellow, brown, and orange. Today the most popular color is blue zircon. Most blue Zircon, which is considered an alternate birthstone for December, is a pastel blue, but some exceptional gems have a bright blue color.

Zircon is mined in Cambodia, Sri Lanka, Thailand, Myanmar, Australia, and other countries.
Zircon is one of the heaviest gemstones, which means that it will look smaller than other varieties of the same weight. Although Zircon is relatively hard, it can abrade and facets can chip. Zircon jewelry should thus be stored carefully. Dealers often wrap Zircons in individual strands of paper so that they will not hit against each other in a package.
