Most of the outer prongs holding in the diamonds were very worn.
The channel for the bagguttes also needed attention.
The 4 prongs holding in the emerald were thin and worn.
I removed the emerald and completely removed the center prongs so I could work on the retipping the diamonds with out fear of damaging the center stone.
The picture above shows all the rebuilt prongs, repaired channel and 4 new wires welded in for the center stone.
As you can see, the prongs are all beefy and the ring looks like new.
