Kiwican,
There is a base layer that is the bracelet itself. Then there is the welt layer with a hole cut out the exact size of the stone. Then there is the set layer with a hole cut slightly smaller than the stone and beveled inward. Has to be just right. If you flex the bracelet enough, you can pop the stone out so I still glue them in. I use marine goop.

Thanks everyone for checking them out.
