Cervandonite is a phosphate mineral consisting of calcium, zinc, phosphate and hydroxide. It typically forms in small, prismatic to tabular crystals with a subdued luster and a color range that can be colorless to pale yellow or greenish hues, depending on impurities. The mineral’s habit and pale coloration make it a subtle but distinctive addition to a cabinet, often appearing in compact aggregates within hydrothermal veins and pegmatites. Notable specimens have been reported from Switzerland and Italy, where it occurs in association with other phosphate minerals and zinc-bearing minerals, and where collectors may encounter well-formed crystals embedded in matrix.

About Cervandonite

Collectors value cervandonite for its rarity and the clarity with which delicate crystal forms can be observed in hand specimens. Although not among the most common phosphate minerals, its connection to classic European localities enhances its appeal for regional or locality-focused collections. When seen in good conditions, cervandonite contributes a refined, understated presence to a mineral display, highlighting the mineralogical diversity of phosphate systems and the varied crystallography of zinc-containing minerals.
