Forgotten stones

While I got my crafting stuff into order, I found a few gems.  I was richer than I thought, gems wise.   I had found a lot of them. Right now, I think I will mainly show the tumbled stones.  Here what I found, enjoy:

I know that on that one, there is at least one snowflake obsidian (botton one, on the far right).

Here, there is an emerald (top left), lapis lazuli (just beside the emerald), three aquamarine (top right and in the middle of the bottom row), garnet (botton right) and the last one, I am not sure (topaz or citrine?  Can be something else entirely):

Here, I don't remember all the name of the stones.  What a shame but they are beautiful anyway.  They aren't in the usual colors of stones I buy but they had attracted my eye:

So, there is a lot of stone that I possess.  I want to do something with them.  Of course, I will do bezel with cutted stones like the garnet and lapis lazuli.  For the tumbled stones, I have a lot and I don't know yet what I would like to do with them.  My main problem is that I don't want to hide them, even if it would be for a silver band with a bezel.  Drilling a hole in them would be difficult.  I don't want to take chances, some of them may be too soft for drilling.  I don't want ending with sand.  I need to think a bit more.
