A market-wide average across qualities and sizes. Your stone's value depends on carat, color, clarity, cut, treatment, and origin.
Painite is an exceptionally rare calcium zirconium borate mineral that gained fame as one of the rarest gemstones. It typically appears in brownish-red to orangey-red hues, sometimes with subtle pleochroism. With Mohs hardness around 8 and good toughness, it is reasonably durable, but most crystals are small and included, limiting gem yield.
