5.1" Polished Chevron Amethyst Sphere - Brazil

Chevron amethyst, also frequently marketed under the names dream amethyst or banded amethyst is a combination of amethyst and white quartz in a banded and often v-shaped pattern. It is found in large veins in rock (not individual amethyst crystals) and often tumbled or polished.

Amethyst is a purple variety of quartz (SiO2) that owes its violet color to natural gamma irradiation, iron impurities, and the presence of trace elements, which result in complex crystal lattice substitutions. It is considered a semi-precious gemstone, and just two centuries ago was considered to have a value on par with diamonds, sapphires, and rubies. The largest and best known amethyst deposits occur in southern Brazil and Uruguay, where they are found in hydrothermally-formed geodes, but many localities around the world produce an amazing variety of amethyst crystals and formations. They are almost always formed in medium- to high-temperature geological settings.
