	Lazurite or Lapis lazuli
		Lazurite is a product of contact metamorphism of limestone and typically is associated with calcite, pyroxenes, and pyrite.
		Lazurite was first described in 1890 from the lapis lazuli district of Badakhshan, Afghanistan.
		Lazurite is a member of the feldspathoid group of minerals.

		Lazurite was considered to be a sacred stone, and the right to manage its production was held by the emir himself.
		Lazurite from these deposits provide faultless specimens for jewelry, and the remaining accumulations, which are unevenly distributed in dolomite marble, are used for the production of mosaics and high quality paint pigment.
		The statue of pharaoh Tutmos III was covered with lazurite, known to the ancient Egyptians as the "sky stone." Raphael, Leonardo da Vinci and Michelangelo Buonarotti used the pigment.

	Lazurite gemstone. Description, wares from lazurite.
		Jewelry lazurite is the polymeric thin or fine and the medium-grained corpuscles, in which grains of lazurite closely grow together with calcite (seldom with dolomite), diopside, phlogopite.
		Lazurite for millenia B.C. in Ancient Egypt, Mesopotamia, and then in Ancient Greece and Ancient Rome was applied.
		The significant quality of lazurite were spent on facing of columns in interior of Isakievskiy cathedral in St. Petersburg; panels, fireplaces and other wares at furnish of lazurite room of the Peterhof palace in St. Petersburg.

	The Metropolitan Museum of Art - Works of Art: Objects Conservation
		Lapis lazuli is a semi-precious stone consisting of the blue mineral lazurite, with secondary silicates and inclusions of calcite and pyrite.
		In addition, the lazurite crystals are smaller, measuring ten microns or less, and the thickness of the paint layer does not exceed forty microns.
		The particle size of the lazurite is ten microns or less, while the percentage of gray impurities lies between the values observed on the two Virgin figures.

		This is the case with lazurite and lazulite.
		Lazurite is the main mineral in the gemstone lapis lazuli.
		In fact, lazurite is part of a family of minerals (the feldspathoids) that never occur stably with quartz.

		The essential part of most lapis lazuli is a blue mineral allied to sodalite and crystallized in the cubic system, which Brogger distinguishes as lazurite, but this is intimately associated with a closely related mineral which has long been known as haiiyne, or haiiynite.
		As the lazurite and the hauynite seem to occur in molecular intermixture, various kinds of lapis lazuli are formed; and it has been proposed to distinguish some of them as lazurite-lapis and hatiyne-lapis, according as one or the other mineral prevails.
		The lazurite of lapis lazuli is to be carefully distinguished from lazulite, an aluminium-magnesium phosphate, related to turquoise.

		Lazurite is distinguished from sodalite by its deeper color and fine grain.
		The opaque, vivid blue, light blue, greenish-blue, or violet-blue stone, consisting largely of lazurite but with appreciable amounts of calcite, diopside, and pyrite, is a rock called [lapis lazuli.] The stone is usually veined or spotted.
		In the past Lazurite has been burned and ground to form the pigment "ultramarine." It was consider an aid to childbirth, and has long been associated with altered states of consciousness and trance work.

		The carbonate mineral azurite has a very similar color to lazurite but is associated with the green carbonate mineral malachite and reacts to acids.

	Along The Great Silk Route (Site not responding. Last check: 2007-11-04)
		Considering separate sections of the Silk Route, the beginning of thecontact and exchanges goes back to the third-second millenia B.C. These relations were established due to exploitation of lazurite in the Badakhshan Mountains and nephrite-upstream the river Yarkend-Darya in the Khotan area.
		Lazurite, extracted in Badakhshan, was exported to Iran, Mesopotamia, Anatolia, Egypt and Syria.
		At the same time with the Lazurite Route, which connected Central Asia and the Middle East with the Mediterranean area and India, there existed the Nephrite Route, connecting eastern Turkestan with China.

		The lazurite found in lapis was used for ages to make the vibrant blue pigment known as ultramarine.
		To produce ultramarine, lazurite was carefully separated out of lapis and ground to a powder that would then be mixed with a binding agent.
		Lazurite can be thought of as a product of a chemical reaction between the mineral nepheline, similar chemically to the common mineral feldspar, and sodium chloride, NaCl, the mineral halite.

	Lapis Lazuli Jewelry & Gemstones
		Lapis Lazuli, or Lazurite is an opaque semiprecious stone characterized by its deep violet-blue color.
		Lapis was the source of the vivid blue pigment known as 'azzurrum ultramarine,' or 'genuine ultramarine' used in fine-art oil paints until its synthesis (synthetic or French ultramarine) in the 1928.
		Lapis is a rock, not a crystal, and therefor is not identified with a particular crystal system, although crystalline Lazurite does occur with a dodecahedral crystal structure.

	Beautiful Blues - Lapis Lazuli - Jewelry Collecting
		Treasured for the vivacity of their color, lapis lazuli gemstones are the perfect accent and/or focal stone in a wide variety of jewelry designs that continually intrigue collectors of blue stoned jewelry.
		Lapis Lazuli is not, like most gemstones, a pure mineral, but rather a rock composed of varying proportions of the minerals: lazurite, sodalite, hauyne, calcite, and pyrite.
		Some purists desire a gem that is almost entirely lazurite, in a deep uniform blue, but most seek a piece with a moderate to generous sprinkling of golden pyrite.

	Lapis Lazuli from Afghanistan
		Royal blue lapis lazuli, the gem variety of lazurite and one of the most beautiful opaque gemstones, is a sodium and aluminum mineral of considerable complexity.
		During the 1880s and early 1900s, lazurite was mined by the “fire-set” method: large fires were kindled at the tunnel face and then quenched with water.
		Lazurite, the main constituent, is isometric, and frequently occurs as dodecahedra.

	Lapis Lazuli
		Lapis Lazuli is a rock composed chiefly of the blue silicate mineral lazurite, together with calcite and brassy-coloured pyrite which are abundant in the poorer quality material.
		The vivid blue of lazurite is cause by the sulphur that forms an essential part of its chemistry.
		At Sar-i-Sang the lapis lazuli occurs as a zone of lenses and veins within white marble, and grades from deep to pale blue with some violet and greenish tints.

	About Lapis Lazuli
		The rich blue color of the lazurite-rich rock, lapis lazuli, is caused by the presence of the sulfur the lazurite contains.
		The small crystals of pyrite that is always present in lapis help to distinguish it from sodalite rock.
		Calcite, another of lazurite's associate minerals produces white streaks in the lapis lazuli.

		The candidates for inclusion in this family and their possible identities in ordinary gemstone language are: lazurite (often called lapis lazuli), azurite, chrysocolla, malachite, and for the last three, these can be mixed in one formation or another.
		Lazurite is entirely different in composition from the other three and as "lapis lazuli," the popular designation of lazurite, would not be found in Arizona.
		The term lapis lazuli is today the popular designation of lazurite, a silicate of sodium, calcium, aluminum, with sulfur, not a mineral but a rock formation consisting of lazurite, and calcite, as well as with pyrite, not actually a metal but having a high iron content.
