Amethyst

.
The etymological origin of the name comes from the Greek amethystos ('amethystos'), this name is due to the belief that the person wearing an amethyst is drunk to drink wine [1]. Another variation of the etymological origin of the Amethyst name derives from the legend in which Bachus the wine god poured wine on a nymph which was transformed into crystal, the crystal becoming violet. Amethyst is also given the role of defense against demons, against theft, this belief explains that the Merovingians' tomb [2] contained amethyst strings.
Amethysts being relatively widespread; in nature, they have been used from the earliest times as adornments and for ritual purposes. The oldest engraved amethyst, as discovered by archaeological excavations, was found in the royal tombs of Mycenae, following the excavations of Heirich Schliemann at the end of the nineteenth century. The beautiful violet gem, dating back to the 2nd millennium BC, is engraved in the inlay, that is, in the deep. Sculpture is a deer that looks, with its head turned, the sucking chick. On the territory of Greece and Asia Minor, amethyst cups were discovered, dating from the first millennium BC
Color [change change source]

A polished amethyst. The specific color that is highlighted by sanding can be seen in the photo.
Mineral has often a violet color, different shades to pink variants. Color is unevenly distributed in the mineral mass, so darker shades appear. Color determinants are made by the presence of Fe4 + ions [3] placed in the atomic structure of the tetrahedral network. The color of the amethyst was due to the replacement of some atoms of iron with atoms of iron, [4] this being a controversial theory. Amethysts can turn by subjecting to radiation [5] into colorless crystals. A similar color change effect is achieved by exposure to sunlight [6] or heat for a longer time to the mineral.
