{"product_id":"bol1-bismuto-giappone-16","title":"BISMUTH – Lab-Grown Rainbow Hopper Crystal, Japan","description":"\u003cp\u003eThis spectacular bismuth specimen is a laboratory-grown hopper crystal, prized for its dramatic stepped, concentric terraces that spiral down toward the center and its dazzling metallic surface awash in violet, blue, gold, green and pink iridescence. Grown in Japan through the controlled cooling of molten bismuth, the piece showcases both a striking geometric architecture and a rainbow of interference colors produced by a paper-thin oxide film.\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 27 x 26 x 21 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 21 g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProvenance:\u003c\/strong\u003e Japan\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ITALMINERAL","offers":[{"title":"Default Title","offer_id":45605281628269,"sku":null,"price":9.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0693\/8027\/6333\/files\/IMG20260402163336.jpg?v=1786489283","url":"https:\/\/www.italmineral.com\/products\/bol1-bismuto-giappone-16","provider":"ITALMINERAL","version":"1.0","type":"link"}
