I was asked to move a large pear shaped diamond from an engagement ring to a new rose gold oval halo mounting that had an oval garnet. I removed the garnet and removed the prongs.
Since there was just a big void where the belly of the stone used to be, I had to make a new bridge to accept the base of the peg head. I laser tacked the bridge in place and soldered it in with “hard” solder. Hard solder has a higher melting temperature then the “easy” solder which I was going to be using in the next soldering step. With small brushes, I polished the bridge. The prongs of her existing mounting were in great shape so I kept her stone in the crown and transferred it over the new ring. I knew I could solder the head in place with “easy” solder without fear of unsoldering the bridge from its place.
Extraordinarily beautiful!! You have great insight for adapting
Best “toy” you have is your laser welder!!
