A market-wide average across qualities and sizes. Your stone's value depends on carat, color, clarity, cut, treatment, and origin.
Petalite is a lithium aluminum silicate mineral that occurs in colorless to white, gray, yellow or pink hues, often with excellent transparency. With Mohs hardness about 6–6.5 and good cleavage in one or more directions, it is moderately hard but somewhat fragile, making it primarily a collector's stone rather than a mainstream jewelry gem.
