| Unlike most other gem materials, lapis lazuli is a complex aggregate of several minerals particularly hauyne, sodolite, nosean, and lazurite. The indefinite composition of the material affects it properties and the density ranges between 2.7 and 2.9. Lapis is also frequently found with inclusions of pyrite. The most famous locality for lapis is in North Eastern Afghanistan. |
