Scapolite is a silicate of Aluminum which cyrstallizes in the tetragonal system with prismatic habit. The crystals are usually found in association with metamorphic rocks. Yellow appears to be the more common color for this material. Faceted scapolite can be especially difficult to differentiate from quartz because many of the gemological properties are the same. Violet scapolites can easily be heated to yellow. |
