Microcline

Microcline is a feldspar gemstone usually tumbled or cut cabochon. It is deep green to blue-green and is sometimes referred to as amazonstone in the Realms. Microcline crystals cleave easily so that finished stones may split if handled carelessly. Tiny cleavage cracks reflect light, so a polished microcline stone shimmers. A typical specimen has a base value of 10gp.
