Calcite," which gets its name from ""chalix"" the Greek word for lime", is a most amazing and yet, most common mineral.
A. Lincoln Sherk MD. collection 1890s-1969
A very unique combination of hemimorphite, conichalcite, and smithsonite. Need a loop to see the smithsonite.
This is a nice specimen from the classic location at Mapimi, Mexico. The rosasite really adds nice color and contrast and displays well.
The hemimorphite from this location are well known for their delicate clear crystals that form beautiful sprays on the limonite matrix.

If you look at this very nice hematite, you will see my hand and camera reflected. That is how shiney this hematite is.
This piece has a great color contrast and looks great! There is very light, unnoticeable damage to some of the crystals.
This is a nice little piece of clear Gypsum, also known as Selenite.
Gypsum is a soft mineral, hydrous calcium sulfate. Gypsum is the standard for hardness degree 2 on the Mohs mineral hardness scale.
Gypsum forms concretions of selenite blades called desert roses or sand roses, growing in sediments that are subjected to concentrated brines.
