A quietly elegant specimen with an almost glassy internal glow.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWHAT WE KNOW\u003c\/strong\u003e\u003cbr\u003ePrehnite is a phyllosilicate mineral (calcium aluminum silicate) typically found in volcanic and metamorphic environments, forming in cavities and veins where mineral-rich hydrothermal fluids slowly crystallize. Its characteristic botryoidal habit — rounded, grape-like clusters of small crystalline masses — is one of the most distinctive formation styles in mineralogy. Color ranges from pale yellow-green to deeper apple green depending on iron content. Delicate inclusions of epidote or quartz may be present within the specimen. This piece weighs 32g. Locality not independently verified.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTHE STORY\u003c\/strong\u003e\u003cbr\u003ePrehnite was the first mineral to be named after a person — Colonel Hendrik von Prehn, a Dutch mineralogist and military officer who brought specimens from the Cape of Good Hope to Europe in the 1770s. It was described and named in 1788, making it a landmark in the history of mineralogy. The botryoidal habit that characterizes most prehnite specimens is produced by the radial growth of fibrous crystals from multiple nucleation points — each rounded mass is a cluster of crystals growing outward from a center, producing the characteristic grape-like surface.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWHY WE CHOSE IT\u003c\/strong\u003e\u003cbr\u003eThe translucence and color on this piece are genuine — the soft internal glow that good prehnite produces is visible in the photographs. At 32g it’s a compact specimen with enough visual character to hold its own in a mineral display.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eABOUT THIS PIECE\u003c\/strong\u003e\u003cbr\u003eType: Prehnite mineral cluster (botryoidal)\u003cbr\u003eWeight: 32g\u003cbr\u003eLocality: Not independently verified\u003cbr\u003eCondition: Natural specimen — please review photographs for color, translucence, and natural variation.\u003cbr\u003eQuantity: 1 — one of a kind.\u003c\/p\u003e","brand":"Found in the Field","offers":[{"title":"Default Title","offer_id":47080784822457,"sku":"XUL92F","price":12.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0782\/9438\/4825\/files\/DBEEE71E-10DF-465D-8413-240207A4A795.jpg?v=1783131437","url":"https:\/\/foundinthefield.store\/products\/prehnite-translucent-green-healing-mineral-cluster","provider":"Found in the Field","version":"1.0","type":"link"}
