{"product_id":"multi-layered-ammolite-specimen-cgss6","title":"Multi-Layered Ammolite Specimen with Dendritic Pattern - CGSS6","description":"\u003cp\u003eA thick piece of ammolite with several layers of colour stacked on top of each other, from the Bearpaw Formation of Southern Alberta. Bright green, gold, orange and red run across the face in large plates, with deep red patches and a dark shale base. You can see the separate layers along the edges.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDendritic pattern.\u003c\/strong\u003e This piece also shows dendrites: fern-like, branching patterns made of mineral, usually manganese or iron oxide. They form when mineral-rich water seeps into tiny cracks in the stone long after it was buried. As that water meets oxygen, the minerals come out of it and build up in branching, tree-like shapes. Dendrites look like fossil plants, but they are purely mineral.\u003c\/p\u003e\u003cp\u003eMulti-layered ammolite is already less common than single-layer material. Finding dendrites in the same piece is unusual, which makes this a distinctive collector's specimen.\u003c\/p\u003e","brand":"Coulee Gems","offers":[{"title":"Default Title","offer_id":67974390579413,"sku":"CGSS6","price":900.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0745\/1269\/5509\/files\/e654abb4-7685-4519-90cd-84b2c00453bd.png?v=1792899172","url":"https:\/\/couleegems.com\/products\/multi-layered-ammolite-specimen-cgss6","provider":"Coulee Gems","version":"1.0","type":"link"}
