Semi Precious Stone Lapis lazuli

Lapis lazuli, also known as just lapis, is one of the stones which have the longest tradition of being considered a gem, with a history stretching back to 5000 BC. Deep blue in color and opaque, this gemstone was highly prized by the pharaohs of the ancient Egypt, as could be seen by its prominent use in many of the treasures recovered from the paranoiac tombs. It is still extremely popular today.
