Gemstones and Birthstones: Blue Zircon — A December Alternative for Turquoise
Hard as it is to believe, some people born in December don’t like turquoise. It may be the color. It may be the fact that it is opaque. Perhaps they prefer transparent faceted stones. You are so lucky. You have two alternatives to turquoise. (And you thought being born in the same month as Christmas was a downer.)

The first one is blue zircon. These hard, brilliant and beautiful stones don’t get half the attention they should. They come in a variety of shades of blue, often mimicking turquoise’s greenish blue. And if it’s the blue of your birthstone you don’t like, zircons come in a variety of other shades of yellow, orange, green and brown. In fact, zircons may have been the original “hyacinth” or “jacinth” of ancient history, however, the term was often applied to many yellow to orange stones.
Zircons have often been confused with other gemstones as they’re part of the plethora of minerals that can be found in the gem gravels of southeastern Asia. They’re as hard as, or even somewhat harder than, quartz (7 to 7.5 on the Mohs Hardness Scale). Their refractive index is literally off the scale (the refractometer scale that is) making them highly dispersive, able to break light into its component colors. They also take a polish similar to diamond.
One weakness of zircons is that they have imperfect cleavage that can be seen as abrasion along the facet junctions if the stones are kept in a single paper together, or if they rub against other jewelry. So store zircon jewelry in cloth bags, do not use an ultrasonic to clean them, and avoid the steamer as well.
