Blue Zircon Jewelry
Zircon is a natural gem which displays a diamond like brilliance due to it's high refractive index of 1.81, which is number related to how strongly a gem will bend light. In the 1930's white zircon was used as a diamond imitation and today it's name is often confused with the diamond imitation cubic zirconia. Zircon is the birthstone for those born in December. Although this gem has good hardness older stones can be recognized by small chips apparent around the facet edges.  Blue Zircon
