Lapis lazuli, as lovely as its exotic name,
has
decorated humans and enhanced their art for
thousands
of years.
Later, royalty, like Catherine the Great of Russia, used it to line the walls of their palaces. Artists in the Middle Ages ground it up to make a luminous pigment called ultramarine, which is the source of the glowing blues in the old masterpieces. Monks also used ultramarine pigment for the illustrations in their finest manuscripts. Lapis lazuli is one of those rare gemstones that occurs in only one color - blue. Its name is a combination of Arabic and Latin words meaning "blue stone." Miners first extracted lapis lazuli from the earth more than 6000 years ago in Babylon (now Afghanistan). Lapis lazuli is still primarily mined in Afghanistan, with smaller mines in Chile, Myanmar (Burma), Russia, and the U.S. Scholars believe that the references to sapphire in the Bible actually allude to lapis lazuli, as all blue stones at that time were called sapphire. Lapis lazuli gets its blue color from lazurite, a complex mineral containing sodium, aluminum, sulfur, calcium, silicon, and oxygen. Other minerals in lapis lazuli may include amphibole, feldspar, mica, apatite, sphene, and diopside. As lapis lazuli is a combination of minerals, technically it is a rock. However, its beauty has allowed it to be classified as a gemstone. A soft (Mohs 5 - 6) and porous gemstone, lapis lazuli needs to be protected from solvents and other chemicals. Jewelry made from it needs to be stored away from harder stones and metals, to prevent damage. Because of its softness, lapis lazuli is often used for carved objects.
