4.8" Polished Lapis Lazuli - Pakistan
This is a 4.8" wide, polished piece of lapis lazuli with streaks of sparkling pyrite running through it. This vibrant blue stone was mined from Northern Pakistan.
Lapis lazuli is unlike most other gem materials because it is not a mineral. Instead, it is a rock composed of multiple minerals. The blue color of lapis lazuli is mainly derived from the presence of lazurite. To be called "lapis lazuli," a rock must have a distinctly blue color and contain at least 25% blue lazurite. Pyrite usually occurs in lapis lazuli as tiny, randomly spaced grains with a contrasting gold color.
