Me too, the names of most escape me.
I was trying to find a cool photo of one I have, to share here, but cannot remember what to search for on the computer. Silly brain. If I remember I will see if I can find it later.
Some larger ones I bought and placed in the garden to enhance the flowerbeds. However, I later realized that the rain would dissolve some of them as they are fragile salt crystals (e.g. selenite), or make others brittle (celestite, I recall, was not happy out there). So I had to gather them all up and put them back indoors on a big windowsill. Pity, it was fun putting nature back into nature.
