How To...Remove a Stone From a Project

Over the years we’ve received a lot of emails asking how to remove a stone so the piece can be polished or heat hardened. In many cases leaving the stone in the piece while performing these procedures will cause damage to the stone. So how can you safely remove the stone from a finished piece.
Solution – The cabochon must be removed in such a way that it causes the least amount of damage. Removing the cab from the front may cause irreparable damage to the piece. Removing the stone from the back of the piece, however, will hide any damage that occurs.

Using flat nose pliers, grab the bottom of the backing wire at the point where it bends away from the frame wires (Picture 1).

Gently bend the wire away from the stone (Picture 2).

Do the same with the top of the same wire (Picture 3).

You should now have one side of the stone exposed (Picture 4). Do the same with the second backing wire.

At this point the backing wires should look like open shutters (Picture 5). From the front of the piece push the stone out the back.

Now you are free to perform whatever necessary procedures that you wish (Picture 6).

When you’re ready to reinstall the stone push it into the piece from the back. With flat nose pliers bend the backing wires back into place against the stone (Picture 7).

To get the wires snug against the stone tap the wires with a rawhide mallet (Picture 8). Be careful not to cause any damage to the stone or the front of the piece.

Please keep in mind that this procedure can only be done to the piece once. The more you bend the backing wires the weaker they become.  The last thing that you need is to grab one of the backing wires and have it snap away from the piece.
