This is a variety of quartz coloured by traces of manganese, titanium and iron. It is of a pale lilac, mauve or bluish violet colour. Very popular in the past, its current value is stable as new mines have recently been discovered. Moreover, its worth has been further undermined over recent years by the flood of tasteless objects made in Brazil.
The best investment is an amethyst of average size weighing between 4 and 8 carats, as dark as possible, but not so much so that the light is prevented from reflecting, and with a deep lustre.
Amethyst has a very wide provenance, but the finest coloured specimens come from Brazil and the Urals. It is also mined in Madagascar, Ceylon, India and Australia.

Amethyst Stone Amethyst is a vivid purple or violet form of transparent quartz
used as a gemstone. The transparent purple quartz is the most popular quartz variety used in jewelry. It was named after the Greek mythological maiden who was turned to stone by the God Dionysus and is characterized by vivid colors and large clean crystals
that make beautiful gems.
Amethyst is a beautiful gemstone available in a wide variety of cut and uncut stones, calibrated sizes and shapes, including many fancy shapes. Because of the patchyness of the color distribution in the crystals, amethyst is cut as brilliant round cuts to maximize the color.
Amethyst can occur as long prismatic crystals that have a six sided pyramid at either end or can form as druzes that are crystalline crusts that only show the pointed terminations. As a mineral specimen, amethyst is popular for its color and nice crystal shapes that produce a handsome, purple, sparkling cluster.
