Turquoise is the one of the official birth stones for the month of December. Planetary stone for Aquarius, Taurus and Sagittarius.

December has two birthstones, turquoise and zircon.

Turquoise is considered by some to be a symbol of good fortune and success, believed to bring prosperity to its wearer. ... The most valued variety of turquoise is an intense sky blue color, like the color of a robin's eggThe name Turquoise is apparently related to the fact that it was brought to Europe from the Eastern Mediterranean by Levantine traders, more commonly known as Turks.  It’s been used as a valuable ornament for ages and was used by the Egyptians thousands of years ago. 

Currently Arizona is the most important value producer of turquoise. There are several mines in the state, two of which are renowned for their distinctive color and performance and regarded the finest in the sector: in August 2012, the Sleeping Beauty Mine in Globe stopped turquoise mining. Due to the increasing world market price of copper, the mine chose to ship all the ore to the crusher and focus on copper manufacturing. The cost of untreated natural sleeping beauty turquoise has increased dramatically since the closure of the mine.

As of 2015, the Kingman Mine is still operating outside the town alongside a copper mine. Other mines include the Blue Bird mine, Castle Dome, and Ithaca Peak, but are largely inactive owing to elevated operating costs and federal laws. Bisbee’s Phelps Dodge Lavender Pit mine came to a halt in 1974 and never had a turquoise contractor. All the turquoise Bisbee was mined with “dinner pail.” It arrived in the dinner pails of miners from the copper ore mine. Morenci and Turkey Peak are either idle or exhausted

The color is, of course, turquoise, but its range of color varies from green and greenish blue to sky blue shades.

The Aztecs mined turquoise in an area now known as New Mexico and a significant amount of turquoise comes from Arizona, California and Nevada in the United States.
