About two or three weeks ago I received a message from a dealer who wrote that he was making a new label for my Pyromorphite from France which I had posted on October 6, 2021. The location information that I had posted in October was the information that I was given and it was not correct. Tobias was correct about the location and Jordi had corrected other misinformation included in that post.
| Mineral: | Pyromorphite on Fluorite, Baryte |
| Locality: | | Chaillac Mine, rossignol vein, Chaillac, Le Blanc, Indre, Centre-Val de Loire, France | |

| Dimensions: | 155 mm x 96 mm x 75 mm |

Very lovely photo. As II often say, keep uploading the close-up shots. They provide so much information about the character and origin of a mineral.

Impressive and beautiful, Don! I guess it's from the open pit mining near Lethbridge. I don't collect fossils but I've heard of that locality in Alberta which seems to produce some really outstanding pieces like that one from your collection and even greater things like a Mosasaur fossil earlier this year.
Is the surface that lustrous by nature or are these specimens polished?

Hello Tobi,
Thank you for your nice comment about the ammolite. If I remember correctly, the dealer that I bought this from told me that the ammolites are coated with a clear epoxy resin.
Don

A really lovely specimen, along with some great photos.
I have often considered uploading a few fossil photos but I do not know if they would be considered minerals. I know they are composed of rock and Calcite.
Anyway a fine contribution - keep up the good work.

Thank you for your nice comment, Silvia. The ammonite shell has calcium carbonate in the form of aragonite and calcite.
Regards,
Don
