Your're right, most specimens are floaters without contrasting matrix. I'm glad to have this specimen where really good dark melanite crystals sit on grey matrix.

I don't know what you mean, Tobi. It looks pretty attractive to me ;-)

Thank you, guys :-)
Don, even if you consider it attractive on this photo - it is even much more pretty in person ;-)
As addition, just for fun, the label i made for the galena when i added it to my collection:
Description: |
Mineral: Black ink on paper matrix Locality: Tobi's printer, Marburg, Germany Dimensions: 40 x 25 x 0,1 mm

I can only offer a detail picture of the ettringite specimen above:

No, there is no doubt about the identification of ettringite. I just thought that you had the opportunity to get a sturmanite from Black Rock Mine. There is a similarity between these minerals, although sturmanite is red-brown and often less prismatic.

Hi Roger, i have no opportunity to get a picture of a sturmanite from Black Rock Mine. Well, of course i can GET one - but i can't MAKE one on my own because i don't have such a specimen ;-)
Here's an old specimen with more and better photos, a mimetite from Badenweiler, Schwarzwald, Germany. It's the same specimen as on the detail picture above:
