December is another month where the traditional and modern birthstones differ. Basically, the December birthstones are all blue -- turquoise, zircon and blue topaz.
Turquoise is one of the oldest jewelry gemstones, with examples having been found in the tomb of Queen Zer, an Egyptian queen, who died thousands of years ago. The name turquoise is derived from a French word meaning Turkish stone. The Turks, however, were just the middleman in the merchant trade for beautiful blue stones from Persia. The Persian turquoise is superbly clear, generally devoid of the matrix normally seen in turquoise from other places. In fact, today the highest grade of turquoise is referred to as Persian turquoise, regardless of where it comes from.

There are many varieties of turquoise, with each mine around the world having distinctive characteristics. This is a chart showing many varieties from American turquoise mines.
The Victorians used Persian turquoise in many of their jewelry, set in both silver and gold (or gold-filled) settings.

Zircon is a wonderful blue gemstone that is not seen a lot today. The blue in the zircon is generally produced by heat-treating clear stones. Blue topaz has somewhat replaced it as the alternate December birthstone. Blue topaz is also the result of heat-treatment of clear topaz stones, but it occurs both naturally and artificially. Either stone is beautiful and create wonderful pieces of jewelry.
