Lapis Lazuli is one of the first treasured stones of human kind, and has been mined for over 7,000 years. Its name stems from the Latin word "lapis" meaning stone and from the Arabic word "azula" meaning blue. This treasured blue stone can be found throughout many ancient civilizations. Before a synthetic substitute was created, it was often ground and used as a pigment, making blue paint, "Ultramarine" the most expensive and valuable paint available. For this reason, blue paint was most often reserved for royalty and holy figures such as the Madonna. Much of the worlds Lapis Lazuli is mined from mountains in northern Afghanistan.

Lapis Lazuli



Introduction. Lapis lazuli is one of the oldest of all gems, with a history stretching back some 7000 years or more. This mineral is important not just as a gem, but also as a pigment, for ultramarine is produced from crushed lapis lazuli (this is why old paintings using ultramarine for their blue pigments never fade).

Color. For lapis lazuli, the finest color will be an even, intense blue, lightly dusted with small flecks of golden pyrite. There should be no white calcite veins visible to the naked eye and the pyrite should be small in size. This is because the inclusion of pyrite often produces discoloration at the edges which is not so attractive. Stones which contain too much calcite or pyrite are not as valuable.
