Gypsum var Selenite - Manitoba, Canada

Fluorescent & Phosphorescent Selenite (Gypsum) – Red River Floodway, Manitoba, Canada

An exceptional cluster of golden-brown Selenite, a variety of Gypsum, from the Red River Floodway in the Winnipeg area of Manitoba, Canada. This locality is particularly interesting to collectors, as the mine from which this material was obtained is no longer accessible, making specimens from this source increasingly difficult to obtain.

The cluster consists of numerous translucent to transparent, honey-gold Selenite blades arranged in an intricate rosette-like formation. The crystals have a beautiful combination of warm golden color, glassy luster, sharp edges, and delicate internal texture. Smaller, silvery-golden crystal groupings fill the spaces between the larger blades, giving the specimen remarkable depth and complexity.

But the real showstopper is what happens under UV light.

This specimen exhibits striking blue fluorescence, transforming its appearance under UV illumination. It also displays phosphorescence, continuing to glow after the UV source is removed. The contrast between the warm golden specimen under normal lighting and its dramatic blue UV response makes this an especially fun and unusual specimen to display and photograph.
