Pair of 18th century Italian angel wings with calcite crystals in sphalerite from the Elmwood Mine in Tennessee. It is an example of the world's finest crystallized calcite. With the unusual formation of sphalerite, it is unequaled by those from any other part of the world (referenced from the "American Mineral Treasure" book, pg. 337).
