Where to find Lapis Lazuli
Sar-e-Sang, Badakhshan Province, Afghanistan
The most historically significant and primary source of high-quality Lapis Lazuli for over 6,000 years. Occurs in crystalline marble within the Kokcha River valley.
Lake Baikal, Siberia, Russia
Another important source, found in marble deposits in the Tultui and Malo-Bystrinskoye areas.
Ovalle, Coquimbo Region, Chile
Significant deposits are found in the Andes Mountains, often associated with copper mines.
Baffin Island, Nunavut, Canada
Smaller deposits have been found in metamorphic rocks.
Colorado, USA
Minor occurrences have been reported in the San Juan Mountains.
Collecting tips
- Look for Metamorphic Zones. Focus your search in areas known for contact metamorphism, especially where limestones or marbles have been intruded by granitic or other igneous rocks.
- Identify Associated Minerals. Lapis Lazuli is often found alongside calcite (white), pyrite (golden metallic), diopside, and other skarn minerals. The presence of these can indicate a favorable environment.
- Observe Color and Texture. The distinctive deep blue color, often with golden pyrite flecks and white calcite veins, is the primary identifier. Look for a granular to massive texture.
- Check for Hardness. Lapis Lazuli has a Mohs hardness of 5 to 6, meaning it can be scratched by a steel file but will scratch glass. This helps differentiate it from softer or harder blue minerals.
- Acid Test (Caution Advised). A small drop of dilute hydrochloric acid (HCl) will cause effervescence (fizzing) on the calcite components of Lapis Lazuli. This test should be performed with caution and proper safety equipment, and only on a small, inconspicuous area as it can damage the rock surface.
Quick Check
- Color:
- Deep blue with golden pyrite flecks and white calcite patches.
- Luster:
- Dull to greasy.
- Streak:
- Light blue (due to lazurite) to white (due to calcite).
