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.
