{"product_id":"polished-dendritic-agate-3pc-madagascar","title":"Polished Dendritic Agate 3pc Bundle - Madagascar","description":"\u003cp\u003eThis Polished Dendritic Agate 3pc bundle is a striking mineral specimen set sourced from the rich, diverse geological deposits of Madagascar. As a semi-translucent variety of chalcedony quartz, this material is defined by its complex, tree-like or fern-like inclusions trapped inside a clear to milky silica body. These delicate structures are formed by a process known as dendritic branching, which occurs when iron and manganese-rich mineral fluids seep into micro-fractures during the initial crystallization of the stone. Over millions of years, these oxides precipitate into dark, branching patterns that contrast sharply against the pale, glass-like background matrix.\u003c\/p\u003e\n\u003cp\u003eThe high-grade refinement applied to this Polished Dendritic Agate highlights the incredible three-dimensional depth of the internal inclusions. Lapidaries apply a smooth, mirror-like finish to the faces of the stone, giving it a vitreous luster that allows light to penetrate deep into the translucent layers. This transparency exposes the fine, web-like boundaries of the dark metal oxides, turning a raw volcanic rock into a pocket-sized natural canvas. Because chalcedony registers a 6.5 to 7 on the Mohs hardness scale, this specimen is highly scratch-resistant and durable.\u003c\/p\u003e\n\u003cp\u003eEach piece of Polished Dendritic Agate is unique, retaining its own organic arrangement of branch formations and matrix tones. The background silica varies from white to a deep, smoky gray, creating an unrepeatable backdrop for the charcoal and rust-colored dendrites. This specimen serves as an informative educational tool for demonstrating non-organic mineral branching, as well as an elegant addition to a professional display case or private rockhound collection. Every item is packed with thick protective materials to safeguard the polished surfaces during transport.\u003c\/p\u003e\n\u003cp\u003eSize: each piece is roughly 2  to 3 inches in size\u003c\/p\u003e","brand":"Desert Oasis Minerals","offers":[{"title":"Default Title","offer_id":55126327820567,"sku":null,"price":25.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/2300\/9559\/files\/1EE78A59-6B55-4F4B-BB1A-E3E4791F6494.jpg?v=1788672351","url":"https:\/\/desertoasisminerals.com\/products\/polished-dendritic-agate-3pc-madagascar","provider":"Desert Oasis Minerals LLC","version":"1.0","type":"link"}
