Willemite is the second most abundant zinc ore from the famous mines at Franklin and Sterling Hill, which comprise the world's greatest locality for fluorescent minerals. This large display piece displays 360 degrees, and is a combination of Willemite, Calcite, and likely Franklinite (co-Type Locality). The reddish-brown Willemite is an amazing 9 cm relatively sharp crystal, and it fluoresceces a classic neon green. The minor Calcite pockets are crystalline and fluoresce a bright reddish-orange. This is a superb specimen of large size for a crystal so sharp and well preserved, and was in the "North Ore Body" display at the Sterling Hill Mineral Museum (display card included). Documented specimens from the North Ore Body at Sterling Hill are extremely rare. Weighing 2.1 pounds, this piece displays perfectly with the large Willemite sitting atop the specimen. Ex. Richard C. Bostwick collection. Bostwick was the mining foreman for the North Orebody before it was closed down - the last working area of the mine. He had the finest collection of such specimens, and they were long displayed in the N.O. Wall section of the Sterling Hill Mining Museum. This was prominent among them, for decades. His collection sold in 2025. Comes with a custom lucite base.
