Hand carved wood display stands are available on Amazon by going to List and clicking on Everything Else and then enter Wood Display Stand.

Question by Angel S: What is the process in which gemstones are polished and shined?
I collect gemstones that are colored (naturally) polished and shined. what is the process they go through to get that way. Or if you have a link to go to that would be helpful.
Thanks!! :]

Answer by thegeologist
Lots of rocks and semi-precious gemstones are processed with a tumbler using different grades of abrasives to smooth them to a rounded and polished surface.
This is not what you'd do with precious stones like diamond or rubies though. That would involve cutting facets and polishing individual faces.
For rock tumbling information, see the link below.
