A market-wide average across qualities and sizes. Your stone's value depends on carat, color, clarity, cut, treatment, and origin.
Microcline is a potassium feldspar mineral, often white, cream, pink or green. Its green variety, amazonite, is the most important gem form, showing blue-green to green hues with a grid-like, microcline twinning pattern. With Mohs hardness around 6–6.5 and good cleavage, microcline is moderately hard but can be brittle; it is best suited to cabochons, beads and ornamental objects rather than heavily worn faceted jewelry.
