Lapis Lazuli is often called Lapis for short. In fact, the shorthand name “Lapis” is actually used more often to describe this gemstone than the full term “Lapis Lazuli”. Lapis Lazuli is rarely without any of the white Calcite present. Embedded Pyrite crystals within most Lapis Lazuli add to the sparkle and naturalness of this gemstone, and when evenly distributed in small amounts makes it more desirable. A deeper blue color makes this gemstone more valuable, as well as a minimal amount of spotting or streaks of white Calcite.
Lapis Lazuli is a sensitive gemstone, and can be chipped or cracked easily when banged. It is also relatively soft so care should be exercised to prevent it from getting scratched. It is also slightly porous and should be protected from chemicals and cleaning solvents.
