Lazurite As A Jewelry Gemstone by Mitch Endick

Lazurite is known by several different names in the gem world and is widely known as lapis lazuli or lapis or, in ancient times, blue rock. This stone should never be confused with lazulite valued as a semiprecious gemstone for many thousands of years, this stone is prized for its deep blue, almost azure color. This is a soft stone so care must be taken when wearing or cleaning jewelry pieces. Gem cutters are not very enthusiastic about cutting raw lapis since it emits a very unpleasant sulfur smell much like that of rotten eggs. Lapis is most often found in varying shades of blue to azure and occasionally yellow or translucent stones can be seen. Lapis has been part of ancient royalty and is unique in its color and alternate uses.

History

With a history dating over six thousands of years, this stone dates back to ancient kingdoms of Babylonia and Persia. The brilliant deep blue color was very often associated by ancient cultures with the blue of the heavens. It was very common in ancient times, right through to the early eighteenth century to ground less desirable stones into a fine powder to be used as pigments for paints and plasters. Many famous art pieces of the Renaissance period employed ultramarine pigments including paintings and frescos. The substance created by the grinding process was referred to ultramarine which was able to be manufactured synthetically since the mid eighteen hundreds. The presence of contaminant minerals such as pyrite can be seen as gold flecks in the stone and these are less desirable specimens. The absence of discolorations can add to the appearance and value of the stones. Lapis can be found in California, Chile and Siberia and the best quality stones are said to come from Afghanistan.
