Buy Zircons

Zircons have been known since ancient times; their name probably originates from Persian and means "golden." However, this gemstone's color palette encompasses a much broader range – colorless, brown, orange, red, violet, blue, and even green zircons are also found. Gray-brown and reddish-brown zircons are the most common in nature, while colorless ones are extremely rare. With a Mohs hardness of 6.5 to 7.5, zircon is one of the more robust gemstones. Pleochroism is characteristic, and is very weak in yellow zircons. These gemstones appear honey-yellow to brown-yellow. However, this pleochroism is more pronounced in blue zircons – they appear yellow-gray to colorless. They exhibit a vitreous to diamond-like luster. Their high light refraction and strong dispersion ensure great brilliance and intense fire. Zircons with a cat's eye effect are also well known. These gemstones are very brittle and therefore sensitive to pressure and impact, and edges can be easily damaged. By firing brownish zircons at temperatures between 800 and 1000 degrees Celsius, colorless and blue varieties can be artificially produced. However, these colors are not always permanent. UV rays and sunlight can also cause slight color changes. Zircon is known for its unique diamond-like sparkle, brilliance, and fire.

Ratanakiri is a Cambodian gemstone deposit known for producing some of the world's finest specimens. It is also the source of the blue variety "Ratanakiri zircon." Other zircons received their names because they are reminiscent of spices, such as the cinnamon and saffron zircons or the Kaduna zircon from Nigeria, which has a warm honey-yellow color. Yellow, yellow-red, and reddish-brown gemstones are still called hyacinth today. The jargon refers to a straw-yellow to almost colorless variety. The blue variety Starlite was created by firing other zircons. Colorless zircons are extremely rare, but their sparkle is particularly striking in brilliant cuts. These gemstones are often used as a substitute for diamonds .

Due to their great similarity to diamonds and their high dispersion, larger zircons are popular gemstones. Would you like an impressive ring with this unique gemstone or zirconium stud earrings ?
