Sodalite crystals are vitreous and transparent to translucent, however massive specimens can appear opaque. Although Sodalite appears similar to Lapis Lazuli, Sodalite is a royal blue rather than ultramarine and rarely contains Pyrite, a common inclusion in Lapis. It is further distinguished from similar minerals by its white streak of Calcite. Sodalite’s six directions of poor cleavage may be seen as incipient cracks running through the gemstone. Clear crystals are very rare and are hardly ever large enough to be faceted. Most specimens are massive and these are polished into ornamental slabs, inlays, carvings, spheres, eggs, beads and cabochons.Sodalite
