Amethyst is a quartz stone and judged by color, clarity, cut and carat. It is an affordable stone and value does not rise much with carat size. The colors range from a faint color to a intense and dark purple, the clarity leads the cut, as amethyst is cut in a variety of fancy and designer experimental shapes, but included amethyst are usually made into cabochons or beads.
- Amethyst can lose color when exposed to daylight. It is not recommended to expose amethyst to sunbathing, or black light. Sudden changes in temperature also affect color.
- Once considered a valuable stone (with diamonds, sapphires, rubies, etc.) The discovery of Brazilian amethyst dramatically reduced the value of the stone.
- The Carat size of Amethyst does not affect value greatly, as it is readily available and common to see large stones. The most valuable grade “Deep Russian” is valued by the deep color. This stone is still lesser value than high grade Rubies and Sapphires however.
