I don't think Mother Nature couldn't have put this specimen together any better than this. Not only does it sit well, but from any angle you turn it, it's a fine specimen. Not to mention the fact that the largest Galena cube is perched nicely on top. The crystal is 2 x 2 x 2.5cm with one corner showing a 111 face. The base is a cluster of six or seven smaller crystals. The Sphalerite is ruby red and are well-defined individual crystals from 2 to 4mm. It is obviously old, from one of the most important historic mining districts in the USA.

A split of a core section polished up on the cut side. The entire section is all Galena and Pyrite. The Galena is hard to see, but everything that is not Pyrite is Galena. Will cost extra to ship.

This is a cool specimen. You probably won't see a good one like this from Galena, Illinois again. The crystals, though with a dull luster, are smooth, sharp and well defined. It is a spectacular ore example from this old American deposit. The only problem with it is a gash in the crystals off to the right in the photos. The matrix is solid Sphalerite. The backside is a plate composed of tiny white Dolomite crystals, Pyrite, and 3-5mm yellow Sphalerite crystals (photos). The DuFoe label states that Smithsonite and Wurtzite can also be found on this specimen. I don't see it, and I belive they mistook the nice yellow Sphalerite for Wurtzite. The label states circa 1969.
The history of this large district, which extends into Wisconsin and Iowa, dates back to 1845. Mining in this district peaked in 1916 during World War I and is said to have had the longest recorded production history in the United States. A good article on MVT deposits can be found in Rocks & Minerals, v64 n1 1989 by Rayond Lasmanis. Much of the information in this Special Edition was found in this excellent article.

I have never seen a Galena crystal group is this one. I do not believe it is cleaved to make it look like this. I believe this to be natural. Perhaps Broken Hill collectors can shed light on this. A bit of almost colorless Fluorite at the base.
