{"product_id":"kambaba-jasper-sphere-b-natural-madagascar","title":"Kambaba jasper sphere (B) — natural, Madagascar","description":"\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eA polished kambaba jasper sphere from Madagascar, green and near-black with the rounded orb patterns that give it its nickname, crocodile jasper. It looks ancient, and its story is usually told wrong: it is widely sold as a fossilised stromatolite, but laboratory testing identifies it as a rhyolite, a volcanic rock, not a fossil at all. The circular \"eyes\" are radiating needles of amphibole minerals, which form in igneous rock, not in the sedimentary layers where real fossils are found. The confusion likely came from a mix-up with a similarly named place in Uganda.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRock:\u003c\/strong\u003e Kambaba jasper (rhyolite; quartz, feldspar, aegirine, amphibole)\u003cbr\u003e\u003cstrong\u003eAlso known as:\u003c\/strong\u003e Crocodile jasper\u003cbr\u003e\u003cstrong\u003eOrigin:\u003c\/strong\u003e Bongolava region, Madagascar\u003cbr\u003e\u003cstrong\u003eHardness:\u003c\/strong\u003e 6.5 to 7 on the Mohs scale; hard and durable\u003cbr\u003e\u003cstrong\u003eTreatment:\u003c\/strong\u003e None\u003cbr\u003e\u003cstrong\u003eDiameter:\u003c\/strong\u003e 8.26 cm\u003cbr\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 805 g\u003cbr\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Acrylic stand included (not the stand shown in the photo).\u003c\/p\u003e\n\u003cp\u003eYou'll receive the exact piece photographed.\u003c\/p\u003e","brand":"The Crystal Showroom","offers":[{"title":"Default Title","offer_id":57925369987416,"sku":null,"price":55.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0778\/4880\/5720\/files\/kj-b-5.jpg?v=1786208839","url":"https:\/\/thecrystalshowroom.com\/products\/kambaba-jasper-sphere-b-natural-madagascar","provider":"The Crystal Showroom","version":"1.0","type":"link"}
