Fluorite with Fluorescent and Phosphorescent Calcite – Balochistan, Pakistan

Fluorite specimen from Balochistan, Pakistan, consisting of an association of crystals partially covered by a cream-white Calcite crust.

The Fluorite features crystals of varying sizes, predominantly cubic in shape, with irregular surfaces and hues ranging from translucent gray to purple.
The Calcite forms a coating made up of dense clusters of small, light-colored crystals, unevenly distributed and particularly concentrated on one side of the specimen.

The most interesting feature of this specimen is its behavior under ultraviolet light.
The Fluorite displays intense purple fluorescence, while the Calcite coating exhibits phosphorescence: after the UV light source is switched off, it continues to emit a residual glow for a few seconds.

This effect, documented in the photographs, is difficult to reproduce faithfully with a camera, but can be observed in person under suitable lighting conditions. The presence of two different luminescence phenomena in the same specimen makes it interesting to collectors of fluorescent and phosphorescent minerals.
