Fluorescent Blue Prehnite with Matrix from Tanzania – 5.86 grams

Light blue prehnite specimen showing blocky, stepped crystal growth with defined faces and a more structured, crystalline habit rather than the typical rounded form. The surface displays a soft luster with translucent areas, while the contrasting dark matrix at the base adds depth and texture.

Under longwave UV light, the prehnite fluoresces a vivid electric blue, dramatically enhancing the visibility of its internal structure and crystal layering. The combination of defined crystal form and strong fluorescence makes this a particularly interesting collector piece.

Fluorescent prehnite from Tanzania is sought after for its unique UV response, especially in examples like this that show more distinct crystal development.
