Zircon is one of the very few gems that have reached the diamond level in fire color and brightness. Its high refractive index and dispersion value make it a beautiful gem.

They are most famous for being colorless because they are very similar to diamonds and have been treated as diamonds either intentionally or unintentionally. Although pure stone is colorless, impurities can produce yellow, orange, blue, red, brown, and green varieties.

The difference from diamond is that it has birefringence and can be distinguished from the wear of the facet edge. Colorless glass and synthetic spinel have been used to imitate zircon.

For more than 2000 years, Sri Lanka has been an important source of zircon, in addition to Myanmar, Thailand, Vietnam, Australia, Brazil, Nigeria, Tanzania, and France.

Zircon has been known since ancient times. Its name is derived from the Arabic "zargun", and this Arabic word is derived from the Persian words "zar" and "gun", meaning "gold" and "color" respectively.

Various colorful zircons also have different names. They are: the red and transparent stone is called Hgacinth or Jacinth; the colorless and transparent stone from Sri Lanka is called Matura Diamond, and it is called "jargon" or "jargoon" stone, derived from the Arabic "zargun", refers to gem-grade zircons of other colors.

The green zircon represents the Kalpa. The eternal tree is a tree of gems, symbolizing the gods of India. Other Eastern countries also believe that the wearer of zircon will be endowed with wisdom, glory, and wealth. It is also a talisman for travelers.
