Occurrences: Lazulite is commonly found in granitic pegmatites and metamorphic rocks. It is often associated with minerals such as quartz, feldspar, and other phosphates. Notable occurrences include Brazil, Austria, Sweden, the United States, and Afghanistan.
Notable Localities: Some significant lazulite localities include the Rapid Creek area in Yukon, Canada; the Serra das Éguas mine in Brazil; and the Rapid Creek area in the Black Hills of South Dakota, USA.
Formation: Lazulite forms in phosphate-rich environments, typically in pegmatites or metamorphic rocks undergoing hydrothermal alteration. The crystal structure of lazulite consists of aluminum, magnesium, iron, phosphorus, and oxygen, contributing to its distinctive blue color.
Unique Features: Lazulite is characterized by its intense blue color, often occurring in prismatic or bladed crystals. The crystals can also exhibit a glassy or vitreous luster. Lazulite's striking blue hue, combined with its distinct crystal habits, makes it a sought-after mineral among collectors.
Uses: Lazulite is primarily valued as a collector's mineral due to its vibrant color and crystal formations. While it is not commonly used in jewelry due to its relatively low hardness, lazulite specimens are treasured for their aesthetic appeal and the unique geological processes that give rise to their formation.
Caution: Lazulite is not considered toxic, but as with handling any mineral specimen, it's advisable to wash hands after contact. Additionally, due to its moderate hardness, lazulite should be handled with care to prevent scratching or damage.
