lazurite

Lazurite at one time was used as a synonym for azurite.

Some minerals leave a streak similar to their natural color, such as cinnabar and lazurite.

Lapis lazuli is a rock, largely formed from the mineral lazurite.

It may be confused with lazurite, lapis lazuli or azurite.

Lazurite crystallizes in the isometric system although well formed crystals are rare.

Lazurite is a silicate mineral with sulfate, sulfur and chloride.

Lazurite is a deep blue to greenish blue.

Lazurite has been mined for over 6,000 years in the district of Badakhshan in Afghanistan.

There was nothing unusual in the bathroom, if one ignored the fact that it was carved from lazurite the colour of a night sky.

Although very similar to lazurite and lapis lazuli, sodalite is never quite comparable, being a royal blue rather than ultramarine.

Sodalite is a member of the sodalite group with hauyne, nosean, lazurite and tugtupite.

Inside, an elaborate shrine was constructed on the exact place of Alexander's death, garnished with topaz, lazurite and other semi-precious stones.

Ground to a powder and processed to remove impurities and isolate the component lazurite, it forms the pigment ultramarine.

The iconostasis is framed by eight columns of semiprecious stone: six of malachite and two smaller ones of lazurite.

Other blue minerals such as the carbonate azurite and the phosphate lazulite may be confused with lazurite, but are easily distinguished with careful examination.

Bystrite occurs in lazurite deposits, and is usually associated with lazurite, calcite, and diopside.

The limestone which formed its basis was impregnated with blue minerals, predominantly haüynite, with smaller proportions of ultramarine or lazurite and traces of sodalite.

Lazurite was first described in 1890 for an occurrence in the Sar-e-Sang District, Koksha Valley, Badakhshan Province, Afghanistan.

Lazurite is a product of contact metamorphism of limestone and typically is associated with calcite, pyrite, diopside, humite, forsterite, hauyne and muscovite.

It occurs as veinlets in lazurite crystals in the Afghan location and in altered limestone xenoliths within pumice in Pitigliano, Tuscany, Italy.

Canary Islands: A pale blue mineral intermediate between haüyne and lazurite has been found in spinel dunite xenoliths from La Palma, Canary Islands.

Ultramarine is the most complex of the mineral pigments, a complex sulfur-containing sodio-silicate (NaAlSiOS) containing a blue cubic mineral called lazurite (the major component in lapis lazuli).

Although somewhat similar to lazurite and lapis lazuli, sodalite rarely contains pyrite (a common inclusion in lapis) and its blue color is more like traditional royal blue rather than ultramarine.

There is only one bystrite deposit that was mentioned in the literature, and that deposit is found in the Malaya Bystraya lazurite deposit located 25 kilometers to the west of Slyudyanka, and just south of Lake Baikal in Russia.

The Scotsman observed and humoured the other's fascination as she watched the die in his hand turn cornelian pink, hyacinth red, amethyst violet, lazurite blue, peridot green... "Have one," he said, reaching again into an empty pocket, knowing it would be the most important thing on her mind from here on.
