Lapis Lazuli Specimens (UV Reactive)

Fluorescent Lapis Lazuli Specimens

Blue Lapis Lazuli specimens from Badakhshan, Afghanistan, a mixture of a good strong blue colour with areas of grey calcite and pyrite.

These are brightly fluorescent under 365nm UV light. Some specimens are a bright orange, others are dotted with bright yellow - it depends on the specific makeup of the rock.

In some cases large phenocrysts are the fluorescent material, sometimes it is veins of calcite, etc.
