Maybe this specimen is not pretty enough, but it records my very first collecting experience.
This is my first Mimetite specimen (in 2009), it's botryoidal, but not exactly the type I want. I was looking for botryoidal mimetite from Congresso-Leon / San Pedro, but was not able to find any on ebay. So I bought this one instead, and told myself: "Well, it's from Mexico, and it's yellow, and botryoidal... keep it instead." :-)
Now I realize that it's an old collection from Santa Eulalia District.
A classic old time Mimetite specimen from Santa Eulalia. A quartzite matrix hosts some silky yellow botryoidal Mimetite across its face.

Two Rhodochrosite stalactite specimens.
The first one shows a twisted growing stalactite.
The second one has orange-brown color due to Fe2O3 I think.

Transparent violet fluorite crystals with lustrous sphalerite. BTW, what's on the surface of fluorite? Are they little chalcopyrite crystals?
