Florescent natural rough Hauynite Crystal - Height: 92 mm - Width: 45 mm- 154 g - (1)

Natural rough hauynite crystals are valued for their rarity and their unique physical and optical properties. Hauynite is a feldspathoid mineral often found in volcanic rocks such as phonolite and nephelinite. Its fluorescence under UV light highlights its compositional uniqueness, making it a fascinating specimen for collectors and mineralogists alike. The rough condition means the crystal maintains a natural, unpolished formation, which can reveal its true morphology and growth patterns. Specimens of this size and weight provide excellent examples of volcanic mineralogy and the diverse compositions of alkaline igneous environments where hauynite typically forms.
