I have some of the rocks on your list in my tanks. Quartz, Malachite, Turquoise, Lapis, Chrysacolla. These are finished rocks and large beads and couple are pendants that used to hang as necklaces. They're in with shells, African trade beads (glass melded beads), and a few pieces of porcelain dollhouse decor. They've been in there for years with no problem. I don't know how unpolished raw rocks would be - possibly okay also?
