Hello Michael, are you sure this is marcasite? I am not sure, but I think, I can see some octahedral faces like for pyrite (with high magnification). Nevertheless, a very nice piece!

Hi Volkmar,

At your suggestion of pyrite rather than marcasite, I just examined the specimen under the microscope. It turns out that both pyrite and marcasite are present. Thanks for your comment and good eye :>)

I spent a few hours yesterday reviewing photos of some of the older pieces in the collection. Some of the images, taken 20+ years ago, were really terrible. I selected some of the worst ones and re-photographed them. The following specimen is one of several pieces I did, and I don't think I ever posted a photo of it, so you won't have to look at the horrible original image.

I remember acquiring this piece 23 years ago at the Holiday Inn Show in Denver. A representative of the Fersman Museum was set up in a room on the second floor and I was really excited to be able to look over all of the specimens on display. At that time, fancy well-lit display cases were a rarity. For the most part, dealers layed flats of specimens on the beds and dresser tops, and tables. I miss those days. Anyhow, this ferberite was one of three pieces that I acquired that day (the other two were a Lorenzenite from the Kola Peninsula and a Cummingtonite from Ukraine).

It is always a great idea to repeat old specimen photos. You now have >20 years of experience.
