Bertrandite Pendants  

A Rare Beryllium Mineral Set in .925 Sterling Silver

Bertrandite was first described in 1883 and named after French mineralogist Emile Bertrand. The mineral occurs as small tabular or prismatic crystals, often forming radiating clusters that catch light in subtle ways. What reaches the jewelry market typically shows these crystalline formations against a tan or brown host rock, creating natural contrast that makes each piece distinct from the next. As a secondary beryllium ore, bertrandite holds interest for mineral collectors and those drawn to geological rarities rather than mainstream gemstones. The material requires careful cutting to preserve its crystal structures while creating stable cabochons for setting. Our pieces pair this uncommon stone with solid .925 sterling silver metalwork. We source bertrandite from verified mineral dealers and have offered it at SilverRush Style since 2005. Prices in this category range from $30 to $250 depending on specimen quality and silver weight.
