Amid the myriad of wholesale minerals and jewelry in Rock Currier's tent a couple of weeks ago, I found the following two specimens. Both were collected by his good friend Bob Bartsch. The pyromorphite was accompanied by Bob's label that indicated it was collected on August 27, 1969. These are the gems that could often be gleaned by looking carefully through Rock's stock. I sure will miss him.
Mineral: | Pyromorphite |
Locality: | Sherman Mine, Burke, Coeur d'Alene District, Shoshone County, Idaho, USA | |
|
Dimensions: | 1.5 x 2.7 cm |
Description: |
Small olive green hexagonal prisms with hoppered terminations. The Sherman mine is in the same district as the more famous Bunker Hill mine, but specimens from the Sherman Mine are not nearly as common. |

Wow, what a cool pyromorphite from Sherman Mine! The hollow structue reminds me of some Chinese ones, but this beauty is much rarer. To be honest, I never heard of the Sherman Mine before ... what a fine pyro!

Michael,
The Pyromorphite, Vanadinite and Rhodochrosite are all killer specimens and great photography.

Thank you Tobi and Don. Tobi, how fortunate you are to live in a town that has a mineral museum. My boyhood hometown also had a museum and that is how my fascination with minerals began.

Believe me, I AM very fortunate to have this museum here!!! And it was the same in my childhood, my passion for minerals began with the first visit there as a primary-school pupil ...

I have been experimenting with a various setups for taking photos of thumbnail-sized specimens. The following two images were made with a bellows attachment. While this setup yielded somewhat acceptable results, I decided it was very cumbersome to deal with and didn't give the flexibility of a good macro lens, which I am now looking for.

This little piece comes from the anatase-rutile occurence in the Cuiaba District. I believe the golden color is a fine coating of rutile on the anatase, but it may be, in fact, a complete replacement of rutile pseudomorphing the anatase. |

I'm enjoying the new Illinois-Kentucky Fluorspar District specimens you are posting Mike. I am not familiar with the Henson Mine (2231 Fluorite - Henson Mine.jpg), the recent wulfenite pictures you took are very beautiful as well. The Kentucky fluorite from East Faircloth (2235 Fluorite.jpg) is wonderful too, the only Kentucky fluorites I typically see are the Danville ones.

Thanks for your comments Jamison. The Henson Mine is in Pope County about 8 miles NW of Rosiclare. Because it is a vein deposit, there were very few cavities and not many mineral specimens were collected. Fluorites from the Kentucky side of the district are not commonly seen at shows, in spite of there being more mines on the Kentucky side. I think this is partly due to the fact that the Denton, Annabel Lee, and Minerva mines produced such an abundance of specimens in comparison to all of the other mines.
