11" Tall, Polished Chevron Amethyst Freeform - Morocco
This is a beautiful freeform made from a deep purple amethyst formation that's known as chevron amethyst. It was collected from a recently discovered amethyst vein in Morocco. The bottom of the specimen has been cut flat so it stands nicely on its own.
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 the rock (not individual amethyst crystals) and often tumbled or polished.
Amethyst is a purple variety of quartz (SiO2) and owes its violet color to natural irradiation, iron impurities, and the presence of trace elements, which result in complex crystal lattice substitutions. It’s 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 but many localities around the world produce an amazing variety of amethyst crystals and formations.
Silicon Dioxide, also know as SiO2 or Quartz, is the second most abundant mineral in the Earth's crust. Quartz crystals generally grow in silica-rich, hot watery solutions called hydrothermal environments, at temperatures between 100°C and 450°C, and usually under very high pressure. Quartz veins are formed when open fissures are filled with hot water during the closing stages of mountains forming, and can be hundreds of millions of years old.
