Turquoise had been used since antiquity like precious and decorative stone because it represents the blue of the sky. It had a big importance during Egypt’s civility because it was used like an amulet or a mascot, especially because turquoise is able to change color. Egyptians interpreted this fact like an imminent danger.
In reality this change of color is done by the influence of light or by cosmetics or by the skin that can prime a chemical reaction.
Turquoise arrived in Europe during the Crusade’s epoch and its name derives from this period. Turquoise means chrome.
