{"product_id":"natural-medium-kambaba-jasper-madagascar-polished-palm-stone","title":"Natural Medium Kambaba Jasper Polished Palm Stone","description":"\u003cp\u003eThis Natural Medium Kambaba Jasper Madagascar Polished Palm Stone is shaped from genuine orbicular rhyolite sourced from West-Central Madagascar. Geologically composed of microcrystalline quartz (SiO2) intergrown with dark amphibole and pyroxene group minerals such as aegirine, this volcanic material features signature dark circular orbicular patterns set within a deep forest-green matrix. Each medium specimen is smooth-tumbled and buffed, remaining entirely free from synthetic color dyes, polymer stabilization resins, or artificial chemical gloss coatings.\u003c\/p\u003e\n\u003cp\u003eExhibiting an effective Mohs hardness rating between 6.5 and 7, this Natural Medium Kambaba Jasper Madagascar Polished Palm Stone delivers high scratch resistance and structural durability due to its quartz-dominated silica framework. The lapidary process produces a vitreous to sub-vitreous surface luster across contoured faces, bringing out the crisp contrast of the internal spherulitic structures. The dense aggregate matrix exhibits a specific gravity averaging between 2.6 and 2.7.\u003c\/p\u003e\n\u003cp\u003eEach purchase fulfills one randomly selected medium palm stone from the representative inventory illustrated in the product photography. Purchasers seeking specific orbicular ring configurations or individual piece selection prior to fulfillment may contact us directly to check available stock. Internal characteristics include fine natural micro-fractures and mineral boundary lines typical of extrusive volcanic rocks, providing an exceptional reference sample for geological study or lapidary collection display.\u003c\/p\u003e\n\u003cp\u003eLocality: Madagascar\u003c\/p\u003e\n\u003cp\u003eApproximate Size: 2 inches\u003c\/p\u003e","brand":"Desert Oasis Minerals","offers":[{"title":"Default Title","offer_id":55136714752279,"sku":null,"price":8.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/2300\/9559\/files\/F487ADD3-08F0-4AA8-9C6C-BD8E7C13F02D.jpg?v=1788813939","url":"https:\/\/desertoasisminerals.com\/products\/natural-medium-kambaba-jasper-madagascar-polished-palm-stone","provider":"Desert Oasis Minerals LLC","version":"1.0","type":"link"}
