Nice collection.
The vast majority of my crystals I have as pendulums or some form of jewelry. Right now I'm quite attached to my Obsidian bracelet that I've been wearing for a while now.

The yellow/orange one is Calcite.
The white one is probably Alabaster, though I'm not sure because it's got a lot of sparkles inside.
The earthy one is Jasper.
