The original marcasite form has been naturally replaced, leaving behind a striking structure now composed of pyrite, while calcite adds contrast and dimension to the overall composition.\u003c\/p\u003e\n\n\u003cp\u003eThe interplay between metallic pyrite surfaces and lighter calcite creates a visually compelling balance, highlighting both texture and structural complexity. The preserved crystal habit gives insight into the original formation, making this piece especially intriguing for collectors who appreciate pseudomorphs and mineral evolution.\u003c\/p\u003e\n\n\u003cp\u003eSourced from a remote and notable northern locality, this specimen is further enhanced by its provenance, coming from a special collection and acquired from Kevin Fearn in December 2001—adding both authenticity and collector significance.\u003c\/p\u003e\n\n\u003cp\u003e𝓜𝓲𝓷𝓮𝓻𝓪𝓵 𝓯𝓸𝓻 𝓢𝓹𝓮𝓬𝓲𝓯𝓲𝓬\u003c\/p\u003e","brand":"Crystal Gemstone AE","offers":[{"title":"Default Title","offer_id":52862979637529,"sku":null,"price":325.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0987\/7215\/6697\/files\/il_fullxfull.8251486042_51q5.jpg?v=1784535419","url":"https:\/\/crystalgemstoneae.com\/products\/calcite-and-pyrite-after-marcasite","provider":"Crystal Gemstone AE","version":"1.0","type":"link"}
