10-strand Lapis Lazuli, Peridot, faceted Amethyst necklace with Sterling Silver embellishments. 18 inches long and designed to be worn twisted.
Lapis Lazuli is a deep-blue metamorphic rock used as a semi-precious stone that has been prized since antiquity for its intense color.
Afghanistan was the source of lapis lazuli for the ancient Egyptian and Mesopotamian civilizations, as well as the later Greeks and Romans.
Mines in northeast Afghanistan continue to be a major source of lapis lazuli. Important amounts are also produced from mines west of Lake Baikal in Russia, and in the Andes mountains in Chile which is the source that the Inca used to carve artifacts and jewelry. Smaller quantities are mined in Pakistan, Italy, Mongolia, the United States, and Canada.
Peridot sometimes called chrysolite, is a yellowish-green transparent variety of olivine. Peridot is one of the few gemstones that occur in only one color.
Peridot occurs in silica-deficient rocks such as volcanic basalt and pallasitic meteorites. Peridot is one of only two gems observed to be formed not in Earth's crust, but in the molten rock of the upper mantle.
The principal source of peridot olivine today is the San Carlos Apache Indian Reservation in Arizona. It is also mined in Arkansas, Hawaii, Nevada, and New Mexico in the US and in Australia, Brazil, China, Egypt, Kenya, Mexico, Burma, Norway, Pakistan, Saudi Arabia, South Africa, Sri Lanka, and Tanzania.
Amethyst is a purple variety of quartz and owes its violet color to irradiation, impurities of iron and in some cases other transition metals, and the presence of other trace elements, which result in complex crystal lattice substitutions.
Amethyst is found in many locations around the world. Between 2000 and 2010, the greatest production was from Brazil, Bolivia, Uruguay, Zambia and Ontario. Lesser amounts are found in many other locations in Africa, Brazil, Spain, Argentina, Russia, Afghanistan, South Korea, Mexico, and the United States.
