Fluorescent Blue Prehnite with Matrix from Tanzania – 5.86 grams Clear Quartz 65 gramsMeasurements: 16mm x 13mmLight 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.
