Lazulite is a rare mineral that belongs to the phosphate class, characterized by its striking blue color. Its name is derived from the Persian word “lazhward,” which refers to a blue color. Lazulite typically occurs in crystalline form, with a distinct prismatic or tabular crystal habit. It has a Mohs hardness of around 5.5 to 6, making it moderately hard.

Lazulite – Things That Rock (

Compositionally, lazulite is a phosphate mineral, primarily composed of magnesium, aluminum, and phosphorus, with chemical formula (Mg,Fe2+)Al2(PO4)2(OH)2. It often forms in metamorphic rocks, particularly in high-grade metamorphic environments where high pressure and temperature conditions prevail. Lazulite crystals are usually found in association with other minerals such as quartz, muscovite, and tourmaline.


  1. Gemstone: Lazulite’s vibrant blue coloration makes it a sought-after gemstone among collectors and enthusiasts. Although it is not as commonly used in jewelry as other gemstones due to its relative rarity, its unique hue and crystal form make it highly prized among mineral collectors.
  2. Scientific Interest: Lazulite holds significant interest among scientists and researchers due to its occurrence in certain geological environments. Studying lazulite and its associated minerals can provide valuable insights into the geological processes and conditions under which these minerals form, contributing to our understanding of metamorphic processes and mineralogy.
  3. Metaphysical and Healing Properties: Like many gemstones and minerals, lazulite is believed by some to possess metaphysical properties and healing energies. It is thought to promote mental clarity, enhance intuition, and encourage self-expression. However, it’s important to note that these beliefs are not scientifically proven and are based on metaphysical traditions and folklore.
  4. Collectibility: Given its rarity and striking appearance, lazulite specimens are highly prized by mineral collectors. Specimens featuring well-formed crystals or exceptional coloration can command significant value in the collector’s market.

In conclusion, lazulite is a rare and visually striking mineral with a vibrant blue coloration. Its composition, geological significance, and aesthetic appeal contribute to its significance in various fields, including gemology, mineralogy, and metaphysical practices.

Physical Characteristics of Lazulite

Certainly! Here are the physical characteristics of lazulite:

  1. Color: Lazulite typically exhibits a rich, deep blue color, ranging from azure to indigo. However, it can also occur in shades of green, gray, or violet, depending on impurities and crystal structure.
  2. Luster: Lazulite has a vitreous to dull luster, often appearing somewhat translucent to opaque.
  3. Crystal Habit: Lazulite commonly forms as prismatic or tabular crystals, often with well-defined faces and sharp edges. It can also occur in granular or massive forms.
  4. Transparency: Lazulite crystals can range from transparent to translucent, with the degree of transparency influenced by crystal size and impurities.
  5. Fracture: Lazulite exhibits a conchoidal fracture, meaning it breaks with smooth, curved surfaces resembling the inside of a seashell.
  6. Cleavage: Lazulite typically shows poor cleavage in one direction, meaning it breaks more easily along certain planes.
  7. Hardness: Lazulite has a Mohs hardness ranging from 5.5 to 6, making it moderately hard. It can be scratched by harder materials such as quartz but can scratch softer materials.
  8. Specific Gravity: Lazulite has a specific gravity ranging from approximately 3.1 to 3.3, meaning it is heavier than an equal volume of water.
  9. Streak: Lazulite usually leaves a pale blue streak when scratched on a streak plate.
  10. Texture: Lazulite crystals often have a smooth to slightly rough texture, depending on the quality of the crystal faces.

These physical characteristics collectively contribute to the identification and classification of lazulite specimens in mineralogy and geological studies.

Formation, Occurrence and Distribution

Formation: Lazulite typically forms in metamorphic environments, where high temperatures and pressures facilitate the crystallization of minerals. It often occurs during the metamorphism of aluminum-rich sedimentary rocks, such as shale or clay-rich rocks, under conditions of regional metamorphism. The presence of phosphorus-rich fluids or hydrothermal activity also contributes to the formation of lazulite. As metamorphic processes alter the mineral composition of the original rock, the necessary chemical constituents for lazulite formation, including magnesium, aluminum, and phosphorus, come together to crystallize into lazulite.

Occurrence and Distribution: Lazulite is a relatively rare mineral, and significant occurrences are limited. It is found in various geological settings around the world, often associated with metamorphic rocks of certain types. Some notable occurrences include:

  1. Granite Pegmatites: Lazulite can occur in granite pegmatites, particularly those enriched in aluminum and phosphorus. Pegmatites are coarse-grained igneous rocks that form during the final stages of magma crystallization and often contain a variety of rare minerals.
  2. Metamorphic Rocks: Lazulite is commonly found in high-grade metamorphic rocks such as gneiss, schist, and marble. These rocks undergo intense heat and pressure deep within the Earth’s crust, creating conditions suitable for the formation of lazulite crystals.
  3. Phosphate Deposits: Lazulite may also occur in phosphate deposits, where it forms as a secondary mineral through the alteration of primary phosphate minerals under the influence of hydrothermal fluids or weathering processes.
  4. Specific Localities: Some notable localities where lazulite has been found include Brazil, the United States (particularly Colorado and Maine), Madagascar, Austria, Germany, and Australia.

While lazulite occurrences are relatively sparse, its distinctive blue color and unique crystal habit make it a sought-after mineral among collectors and enthusiasts. Exploration efforts continue to uncover new occurrences and expand our understanding of lazulite’s distribution worldwide.
