Bruce , did you use anything special to set the stones ?
With much regret, I use an adhesive product called Gem-Tac that I got from Ben Franklin. I have used it before and it seems to hold the stones well. I do use a bur designed to leave the correct angle to drill the hole. These are available from Rio Grande and other jewelry supply houses.
My regret is that despite numerous attempts I am still unable to set a stone the proper way, not scar the metal beyond repair and have it stay put. In an ideal world, the metal should be pushed over the wide part of the stone holding it place. I have done bezel and prong settings, but the pave still baffles me. Wish there was a local class for this, but its on my bucket list.
