Almandine is a precious garnet of deep red to purple color that is most often faceted for rings. Like other members of the garnet group, almandine also forms rounded crustals with 12 rhombic or 24 trapezoidal faces. Garnet gemstones of almandine are popular for their excellent hardness. A rare size 4-inch diameter almandine garnet costs about $800, whereas sizes of 1 to 2 inch diameter are priced at $50 to $150. In the US, there are many localities where almandine is found. Fine crystals of almandine embedded on mica-schist occur near Fort Wrangell in Alaska. The coarse varieties of almandine are often crushed for use as an abrasive agent.
