What is Pinolite?
Pinolite is a very rare semi-precious stone mined only in Austria and Spain. When cut into cabochons, the surface reveals a peanut-pattern in black and white. These peanut-like shapes are actually the Magnesite crystals, trapped in a substrate of other minerals. Pinolite is a fragile material, but small amounts are turned into beads, cabochons, and tumbled stones.
