Very Rare Hemimorphite on Dolomite + Sphalerite, Mattie Mae Mine, Rush, Arkansas
From the Rush Mining District, Marion County, Arkansas.
Very rare (and fluorescent/uv reactive) combo of Hemimorphite on Dolomite and Sphalerite. Mined by Henry Delinde/ex Henry Delinde collection.
Mined many decades ago when collecting was possible. The Rush mining district is now strictly off limits to collectors as it is now zoned as a National River under the US National Park Service.
Exceptional piece here, from our personal collection of "Best of Arkansas Minerals".
