Superb crystal of Hauyne var. Lazurite. Lazurite is no longer a species, and is now classified as a variety of Hauyne. It displays very sharp, well-formed and complete all over rhombic dodecahedron of 20mm.  It has deep and saturated royal blue color. Often  Lazurite crystals are very difficult to find and not well formed, while this one is perfect. Some small unidentified minerals are seen too. For references see the issue of The Mineralogical Record vol. 45, # 3, May-June 2014. In superb condition. On acrylic base.

Wonderful Lazurite crystal!
