A market-wide average across qualities and sizes. Your stone's value depends on carat, color, clarity, cut, treatment, and origin.
Axinite is a group of calcium aluminum borosilicate minerals that typically form sharp, wedge-shaped crystals. Gem-quality axinite is usually brown, violet-brown or grayish, with strong pleochroism and Mohs hardness around 6.5–7, but it is brittle and has excellent cleavage, limiting its use in everyday jewelry.
