|
|
Another Tucson is in the books. The weather during our visit was wonderful and it was a shock to return home to snow, sleet, ice, and freezing temperatures. There were a few new mineral discoveries (see Bob Kerr's Tucson report for details), but by and large nothing notable creating a big buzz. I continue to focus on old collections that become available, and in one such collection I was able to find a nice Bleiberg wulfenite that didn't break the bank. I have wanted to add one of these to the collection for many years, so that piece made my day. I have been busy photographing our new acquisitions and will post a photo later.
Below are a few thumbnails that we took home.

|
| Dimensions: | 2.6 x 2.0 cm |
| Description: |
| While there were several dealers that had calcites from the 2022 discovery, finding a thumbnail specimen proved difficult. |

That malachite is a great specimen, Michael!
Malachite from Grube Friedrich is an absolute classic from Siegerland, and many collectors consider them the best malachites from Germany.
And though I don't collect malachite, I think you are lucky that you have found such a good specimen of this classic material.
Congratulations :-)
Best regards
Tobi
