{"product_id":"tano-hedembergite-quarzo-prasio-toscana-0","title":"PRASE QUARTZ \u0026 HEDENBERGITE – Green Crystals on Matrix, Rio Marina, Italy","description":"\u003cp\u003eThis aesthetic specimen combines numerous lustrous, deep green Prase Quartz crystals resting on a striking matrix of radiating (sheaf-like) Hedenbergite. The intense green tone of the quartz, caused by fibrous mineral inclusions within its structure, creates a bold visual contrast against the darker pyroxene matrix, highlighting the sharp geometry of each crystal. The piece comes from the historic skarn deposits of Rio Marina, Elba Island — a classic Tuscan mining district whose mines have been closed since 1981, making fresh material of this combination genuinely uncommon on today's market.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMineral Data:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 96 x 96 x 74 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 363 g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProvenance:\u003c\/strong\u003e Rio Marina, Rio, Livorno Province, Tuscany, Italy\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ITALMINERAL","offers":[{"title":"Default Title","offer_id":45737288106093,"sku":null,"price":119.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0693\/8027\/6333\/files\/IMG20260715210149.jpg?v=1788063925","url":"https:\/\/www.italmineral.com\/products\/tano-hedembergite-quarzo-prasio-toscana-0","provider":"ITALMINERAL","version":"1.0","type":"link"}
