What is zircon?
Zircon is a natural gemstone. It is composed of zircon silicate and is found in a number of regions around the world, including Sri Lanka, Burma, Cambodia, USA, South Africa and Australia. It has been used in jewelry for centuries and particularly as a diamond simulation.
The word zircon comes from the Persian word ‘zargun’ meaning ‘gold-colored’. However, you can find zircon in a range of colors, caused by various impurities that are present during the formation of the stone. Sometimes zircon can contain traces of uranium, and can be slightly radioactive. In such cases, the zircon undergoes stability treatments to enable them to be used in jewelry. However, don’t let this stop you from adding zircon to your jewelry collection because the mini scale levels of radioactivity found in zircon jewelry pose no health risks for humans.
Zircon has very high sparkle, luster, dispersion and refraction. In other words, it plays excellently with light, making it a brilliant and fiery stone. Zircon also exhibits rainbow flashes of color.
Because the stone has double refraction, it displays excellent fire and may give off the illusion of having double the number of facets that it actually has. This infringement, however, can also cause the zircon to appear fuzzy.
Evaluating zircon color
While the most popularly used zircon varieties include blue, pink, yellow and colorless, you can find this stone in almost every color.
Colorless zircon is the purest form of the mineral and high quality, diamond-like stones can be very rare. In fact, it is much rarer than diamonds but is considerably less valuable.
