Natural Large Kambaba Jasper Polished Palm Stones

These Natural Large Kambaba Jasper Polished Palm Stones are crafted from green orbicular rhyolite sourced from West-Central Madagascar. Geologically composed of microcrystalline quartz (SiO2) intergrown with dark amphibole and pyroxene group minerals like aegirine, this volcanic rock displays dark circular orbicular patterns embedded within a deep forest-green matrix. Each large palm stone is shaped and smooth-tumbled, remaining completely untreated without synthetic color dyes, polymer stabilization resins, or artificial chemical coatings.

Exhibiting an effective Mohs hardness rating between 6.5 and 7, these Natural Large Kambaba Jasper Polished Palm Stones offer high resistance to scratching and surface wear due to their high silica content. The lapidary polishing process reveals a smooth, vitreous to sub-vitreous luster across contoured surfaces, emphasizing the contrasting orbicular swirls without altering the natural mineral substrate. The aggregate rock features a dense specific gravity averaging between 2.6 and 2.7.

Each purchase fulfills one randomly selected large palm stone from the representative inventory shown in the product photography. Purchasers requesting specific orbicular patterning or individual piece selection prior to fulfillment may contact us directly to check available stock. Microscopic features include fine natural micro-cracks and crystalline inclusions typical of extrusive volcanic mineral formations, serving as an exceptional petrological specimen for geological collection reference or lapidary handling.
