This is the story of a Silpada ring and the stone that had slipped down inside the setting. At first glance it seemed that the stone possibly had taken a hit and the stone shoved further into the open setting and off what I hoped was just a step bezel. Not so.
It was my hope that this stone had just been pushed down over the edge of a step bezel, which is a bezel setting where the bezel is not soldered to a solid base but has a small ledge for the stone to rest on, thereby leaving the back of the stone exposed. However, when I lifted the stone from the ring, this is what I saw. The wall of the bezel was thick, much thicker than normal, and appeared to be a cast piece instead of a constructed piece. In order for the stone to have a ledge to rest on and in lieu of a solid base, a burr had been used to carve out a 'step' so that the stone (in theory) would snap into position and not move. [Not a particularly safe way to set a stone (obviously, since I repaired it) and as a craftsperson, I would never construct this setting for a stone I thought was important but probably it was easier and less time-consuming for the maker of this piece. Workmanship is important when you want your work to last.]
My solution was to use sandblasting media which, in this case, is super fine glass particles that I mixed with epoxy and slowly built up the inside of the ring so the stone would have a solid bed to sit on. Once dry, it ought to have a bit more durability than before. There are some who advocate the use of sawdust to create a base but I would think that if your hands were in water and a ring you were wearing had a sawdust base, that the water could seep into the setting and expand, causing the stone to loosen and pop out. Just a thought. And I don't think sawdust is a particularly good solution.
