It may have come from the word Turquie, French for Turkey, because of the early belief that the mineral came from that country . Another possibility could be the name came from the French description of the gemstone, "pierre turquin" meaning dark blue stone. In fact the word "turquoise" is derived from the French word for "Turkish."some says that it derived of the word"FIROUZEH" that it has changed of the word "PIROUZI"means "VICTORY".
