Lore & History:   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."
   
Toughness & Hardness:   The hardness of Zircon is 6 to 7.5 on the Mohs scale.
   
Care & Cleaning:   Zircon is hard but can be brittle. Try not to expose your zircon to impact or abrasion. Store zircon jewelry with care to avoid scratches. Clean with mild dish soap: use a toothbrush to scrub behind the stone where dust can collect.
   
Price Range:   $25 to $250 per carat. Exceptionally fine gems can command even higher per carat prices.
   
Special Characteristics:   Natural zircon today suffers for the similarity of its name to cubic zirconia, the laboratory-grown diamond imitation. Some don't realize that there is a beautiful natural gemstone called zircon. Zircon occurs in a wide range of colors but for many years, the most popular was the colorless variety that looks more like diamond than any other natural stone due to its brilliance and dispersion.
