| Title | Lazurite |
|---|---|
| Description | Lazurite is a silicate whose well-formed, deep blue crystals are rare and valuable. Lapis lazuli or lapis, for short, is mostly lazurite but commonly contains pyrite and calcite. The rich blue color is due to the sulfur that is inherent in the structure of lazurite. The original source in Afghanistan still produces the finest quality material. Na3Ca(Al3Si3O12)S is lazurite's chemical formula. The name comes from the Persian, lazward, meaning blue. |
