This is beautiful, looks like bubbles in the stone.  Please share how you worked the back of the chalcedony to get this look.

I ground the hole with a diamond ball bur. Sanding was done with wood dowel pieces shaped with a file and mounted on a screw tip mandrel. I used tumbling grit to sand the holes. Using another wood shaped dowel I polished the hole.
In an upcoming article in Rock and Gem Magazine under the heading "Bench Tips" I wrote a detailed description on how to do this work. I believe the article will be in the next (August) issue.

Thanks for the explanation. I've just bought a subscription to Rock and Gem, hopefully I'll get the September issue.
