{"product_id":"ammonite-and-black-onyx-necklace","title":"Ammonite and Black Onyx Necklace","description":"\u003cp data-start=\"34\" data-end=\"679\"\u003eThis Ammonite and Black Onyx Necklace brings together a fossil from ancient oceans and a striking natural mineral. The piece features a fossilized ammonite paired with polished black onyx, both set in sterling silver. Ammonites were spiral-shelled marine mollusks that lived during the Mesozoic era, and their shells were preserved through fossilization over millions of years. Black onyx is a variety of chalcedony, a microcrystalline form of quartz formed as silica-rich fluids deposit layers within rock cavities. Together, these natural elements highlight the intersection of paleontology and mineralogy in a wearable piece of earth science.\u003c\/p\u003e\n\u003cp\u003eWhy You’ll Love This\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-start=\"681\" data-end=\"1266\"\u003eFeatures a real fossilized ammonite paired with polished black onyx, connecting ancient marine life with natural mineral formation.\u003c\/li\u003e\n\u003cli data-start=\"681\" data-end=\"1266\"\u003eSet in sterling silver for a durable, polished finish that complements the fossil and stone.\u003c\/li\u003e\n\u003cli data-start=\"681\" data-end=\"1266\"\u003eSmooth, opaque black onyx provides bold contrast to the spiral pattern of the ammonite fossil.\u003c\/li\u003e\n\u003cli data-start=\"681\" data-end=\"1266\"\u003eDemonstrates fascinating geologic concepts including fossilization and the formation of quartz minerals.\u003c\/li\u003e\n\u003cli data-start=\"681\" data-end=\"1266\"\u003eA thoughtful accessory for fossil collectors, geology enthusiasts, and anyone who appreciates science-inspired jewelry.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"1268\" data-end=\"1394\" data-is-last-node=\"\" data-is-only-node=\"\"\u003eCelebrate the natural history of our planet with a necklace that showcases both ancient life and remarkable mineral formation.\u003c\/p\u003e","brand":"The Science Museum of Minnesota","offers":[{"title":"Default Title","offer_id":48238902771926,"sku":"308P","price":59.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/2491\/1830\/files\/New_Store_Site_-_Background_Remover_22_0be640d6-6fc5-47ec-8b20-05e8d0e77944.png?v=1778441827","url":"https:\/\/threecrows.com.co\/de\/products\/ammonite-and-black-onyx-necklace","provider":"ThreeCrowsLLP","version":"1.0","type":"link"}
