{"product_id":"kambaba-jasper-sphere-a-natural-madagascar","title":"Kambaba jasper sphere (A) — natural, Madagascar","description":"\u003cp\u003eA polished kambaba jasper sphere from Madagascar, deep forest green scattered with dark orbs and swirls. Here is the honest part most sellers skip: despite the name, kambaba jasper is not a jasper, and it is not a fossil. Lab analysis (X-ray diffraction) shows it is a rhyolite, a volcanic rock, made mostly of quartz and feldspar. The green comes from minerals like aegirine, and the dark \"eyes\" are tiny needles of amphibole that grew in radiating circles as the rock cooled. It is often sold as fossilised algae billions of years old; that is a long-repeated myth, and the geology says otherwise.\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 5.88 cm\u003cbr\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 285 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":57925294948696,"sku":null,"price":22.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0778\/4880\/5720\/files\/kj-a-6.jpg?v=1786208035","url":"https:\/\/thecrystalshowroom.com\/products\/kambaba-jasper-sphere-a-natural-madagascar","provider":"The Crystal Showroom","version":"1.0","type":"link"}
