Mimetite, Wulfenite

This specimen showcases an abundance of bright orange, gemmy, and highly lustrous wulfenite crystals on vibrant canary-yellow mimetite. The mimetite drapes the matrix, extending across the front, over the top, and onto the backside, making for a visually striking sample. These vivid, eye-catching crystals are characteristic of the Rowley Mine, located in the Painted Rock Mountains, about 27 miles west of Gila Bend, Arizona. Discovered in 1900, the Rowley Mine began production around 1909, with its final recorded mining activity in 1923. Today, it operates on a small scale, primarily mining for specimens and occasional material such as massive chrysocolla.

Renowned for producing some of the finest wulfenite specimens in North America, the Rowley Mine is celebrated for its rich orange crystals with exceptional crystal forms. This specimen is a superb example, displaying the striking characteristics that make Rowley Mine wulfenites highly collectible. Its brilliant colours and dazzling crystal quality make it a standout piece that would effortlessly capture attention in any display cabinet.

This specimen comes from the collection of Dr. Peter Tarassoff, a prominent figure in mineralogy, particularly known for his work at Mont Saint-Hilaire (MSH). His diligent collecting and examination efforts have led him to be the first to identify at least 35 species and discover 12 new species, not only at MSH but also at other alkaline localities. Dubbed the "Dean" of Mont Saint-Hilaire collectors, Peter was honoured with the naming of the new species petarasite in 1980. He has authored or co-authored numerous mineralogical articles and has been a member of the Mineralogical Association of Canada since 1964. Additionally, Peter has volunteered at the Redpath Museum for the past 21 years, where he was formally appointed the Honorary Curator of Mineralogy. In recognition of his significant contributions to mineralogy, Peter was awarded the 2017 Pinch Medal.
