Darlan's multi size adjustable castings

Abstract

While looking for castings I realized that you have to buy a separate casting for every gem, this can become very expensive. That's why I came up with the idea to create a casting that could be adjusted to fit several different sizes of stones in one casting: The casting would be on a spring slide to hold the gem tight. There will be a release mechanism to move slide to desired position and tighten down to hold gem. When the tool is removed the gem locks in place. This idea will work for rings, earrings, necklaces, bracelets or broaches. You can switch the gems to match different outfits. With this idea one casting can work for several size stones, you only have to buy a different shaped casting.

1 . The casting would be on a spring slide to hold the gem tight. There will be a release mechanism to move slide to desired position and tighten down to hold gem. When the tool is removed the gem locks in place. I am still working on the special tool to release mechanism. This idea will work for rings, earrings, necklaces, and bracelets or broaches.
