The Mineral Lazulite

Many a time confused with Lazurite, Lazulite is an aesthetic blue mineral with distinct crystals and is entirely different from the range of minerals to which the former belongs. Lazurite forms a sequence with atypical mineral Scorzalite, which is an iron-rich counterpart of Lazurite.

Chemical Formula
(Mg, Fe) Al2 (PO4) 2 (OH) 2

Derivation of Name
Lazulite gets its name from an Arabic word for heaven because of its sky blue color.

Occurrence
It is found in metamorphosed schists, igneous pegmatite dike (Wiki Describes Dike as “A dike or dyke in geology is a sheet of rock that formed in a fracture in a pre-existing rock body") and deposits of hydrothermal replacements.

Gemology
It is a favorite mineral of collectors. Its variety from Rapid Creek (Yukon) and Graves Mountain (Georgia) is particularly valued. Its specimens implanted in white quarts, particularly from Austria are at times polished or cut into slabs for collectors. Minor collectors infrequently use it as a gemstone.

Source
Prominent locations: Western Austria; Switzerland; Zermatt, Brazil; Minas Gerias, Lincoln County., Georgia; Yukon Territory, Canada and Inyo County, California.

Mineralogy
This relatively unusual mineral gets easily confused with other, better known minerals. Apart from just sounding like the silicate mineral Lazurite, it has quite similar looks too! Certainly, its color is exceedingly similar to Lazulite and the carbonate, Azurite. The gorgeous variation of blue color that comes with all three of these minerals makes them very pleasing as ornamental stones. Azurite acts with acids and Lazurite forms uncommon and different crystals than Lazulite.

Color
Color varies from dark azure-blue to a bright indigo blue or even a pale sky blue.
