Rhodochrosite
Hello Don, Is the matrix entirely Pyrite or combined with another mineral? Dany.
Hi Dany, I think Pyrite.
For sure. There are many combinations with sulfides from Pachapaqui, but these rhodochrosites are typically sitting on pyrite.

Dany, I looked at this specimen just now for the first time since I took the picture to post and it is Rhodochrosite on Pyrite and there are no other associated minerals that I can see.
