The value of green amethyst is determined by several key factors, including color, clarity, cut, and carat weight. The crystal that radiates a rich, evenly distributed green color without any visible complexions or flaws is the most valuable one. The gemstones that possess dark green color are mostly more valuable than those gemstones that possess lighter shades. Like other crystals, the cut of the green amethyst also influences Green Amethyst Value, with well-proportioned and expertly faceted stones commanding higher value.
