Turquoise

Turquoise is a greenish-blue color, named according to the gemstone turquoise. The French term "pierre turquoise" originally meant a "Turkish stone"; turquoise was imported to Europe via Turkey. In Turkey, the color has been extensively used in decorative tiles of homes and places of worship. Turquoise has been a gem and a decorative stone since the cultures of Egypt, Mesopotamia, Persia and the Aztecs. Also imitations of turquoise gems have been produced since ancient times.

Turquoise is fragile matter, whose color originates from copper and copper aluminate. Turquoise is typically found in arid, volcanic regions, in fractures and cavities. The most important producer of turquoise is Iran, where the stone is natural blue. Other suppliers of turquoise include e.g. Egypt and the United States.

Turquoise is a color of the sea, implying purity and freshness. Hence, it can be found in many spas, swimming halls and bathrooms.

In many cultures, turquoise has been considered a color that protects against untoward things. For instance, in Greece and other countries of the Mediterranean, door and window frames have often been painted turquoise in order to evict evil spirits. The inhabitants of ancient Pompeii and Rome favoured the color in their villas; some statues of the time had turquoise gemstones as their eyes.
