Sagittarius' astrological gem is the TURQUOISE.

Turquoise is a vibrant light-blue stone often seen in Southwestern jewelry. Real turquoise is reasonably priced and quite lovely to behold.

The name turquoise may have come from the word "Turquie", French for Turkey, because of the early belief that the mineral came from that country. (In fact, most of today's finest-quality turquoise in the world comes from the United States, particularly Arizona, California and New Mexico). Another theory is that the name came from the French description of the gemstone, "pierre turquin", meaning "dark blue stone."

When worn by a Sagittarius, the turquoise is supposed to help them to start new projects. In the past, turquoise has been thought to warn the wearer of danger or illness by changing color. It is also believed to bring happiness and good fortune to those who wear it regularly.

Turqoise in Legend:
Turquoise is probably one of the oldest gemstones known. It was being used before 4000 BC, and was popular in jewelry worn by the ancient Egyptian Pharaohs and Aztec Kings. In the 13th century, turquoise was thought to protect the wearer from falling, especially from horseback. In the more recent past, this gemstone was extensively worn and used by Indian tribes in the U.S. Southwest and in Mexico. An Indian legend said that if turquoise was affixed to a bow, the arrows shot from it would always hit their mark.
