This piece shows the calcite\/willemite combination this district is renowned for worldwide: brilliant red-orange fluorescing calcite set against vivid green-fluorescing willemite under shortwave UV, a color contrast that has made Franklin\/Sterling Hill material the benchmark against which all other fluorescent mineral localities are measured.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003ePhotos were taken under a 70W shortwave (SW) lamp. Fluorescent response is highly dependent on lamp wattage, wavelength, and bulb condition — results under your own UV light may appear more subdued or more vivid depending on your setup. In daylight, this specimen presents as unassuming calcite\/willemite matrix; the fluorescent show only appears under UV.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eSpecimen Details:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eApprox. specimen weight (g): 576 grams\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eApprox. specimen size (mm): 90mm x 80mm x 50mm\u003c\/strong\u003e\u003c\/p\u003e","brand":"Rad Man Minerals","offers":[{"title":"Default Title","offer_id":54400013861148,"sku":"3108","price":40.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/5524\/1500\/files\/P9060021.jpg?v=1788724743","url":"https:\/\/radmanminerals.com\/products\/fluorescent-calcite-willemite-sterling-hill-mine-franklin-new-jersey","provider":"Rad Man Minerals","version":"1.0","type":"link"}
