Dendritic chalcedony is a variety of quartz, with the formula SiO2, made of microscopic fibrous crystals and marked by tree-like manganese and iron inclusions. Chalcedony was described in scientific literature as a distinct mineral term for these fibrous quartz aggregates, and the name comes from Chalcedon, an ancient place name. Such dendritic markings create the familiar moss-agate look prized in decorative stone.\u003c\/p\u003e","brand":"Crystal Castle","offers":[{"title":"Default Title","offer_id":49359378022555,"sku":null,"price":6.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0336\/3012\/6217\/files\/a6157099-e83f-4342-a07d-f8595cc8b584_3b16fc6c-6588-4df2-aa95-0d08c5157b1e.jpg?v=1787518994","url":"https:\/\/www.overtonfamilyjewels.com\/products\/auction-win-75a51678-9fc4-41f5-9d5a-78c402fee9a7-1","provider":"OFJ's Crystal Castle","version":"1.0","type":"link"}
