Thank you @melinda010100! Wouldn't it be cool to
have a indoor water feature with the pretty rocks all
around! :-)

That would be a fun way to display them, and there are certainly many that look prettier when they are wet.

Especially the agates, like to put them in a frame with
both sides glass with some silicone and put the rocks
and water in, then hang in a window, how's that sound? :-)

Oh, I can only imagine how beautiful that would be!
