Holy cow!! Where do you get these smoking veszelyites?
Keep 'em coming, okay?

In my case it was being in the right place back in 1999. At the time it was one of the most expensive minerals in my collection and still is. Thank you for the comment, I only wish I had more.

Gallatin Canyon calcite is so lovely, here's one of mine.
Description: |
Calcite Gallatin Canyon, Montana, USA 17 X 10 X 6 cm This is a fine, classic Gallatin Canyon calcite specimen. It is nearly a floater, I can find only two 1-cm points of attachment from what must have been a large pocket with branching, lobular matrices in it, covered with tiny calcites. On top of those grew the large golden scalenohedrons. The largest calcite is 7.5 cm (3 inches) and is doubly terminated. All the large scalenohedrons are undamaged. The overall size of this grand specimen is 17 X 10 X 6 cm. The specimen was passed from Ronald L. Anderson of Littleton, CO to the Buckskin Booksellers of Ouray, CO. I purchased in from Robert Stouffer, also of Ouray, CO. |
