We refinish rings to like new condition all the time. But I always love refinishing an engagement ring right before the wedding day. It is rewarding to make it look it’s best for that special day.
This classic platinum ring required some prong work and needed to be totally repolished for the big day. Instead of sanding out the light scratches and small dings, I used a tungsten burnisher to move and manipulate the malleable metal back into the dents. Much less material is removed. And the best part, the surface becomes harder when you work the surface with the burnisher, which makes it more scratch resistant.

When I refinish a ring, instead of sanding out dents, scratches and dings, I use a number of burnishing burs to move and push the metal into the dings. (See picture below)
At this point, the surface is fairly smooth. It takes very little sanding to make it flat. I love to use rubber abrasives instead of sanding discs.
If money is tight and you don’t want to spend the $25-35 for the tungsten burnishers you can make one using a used burr. Heat it up to anneal it. I bend it while I am torching it.
For polishing, my number one bench jeweler tip is using a used sanding disc on the mandrel upside-down and charge it with tripoli. You can get into tight places and keep a crisp, flat surface.
This method takes a little bit longer, however, the results are much better then just sanding out blips. Another bonus is that burnishing the ring “work” tempers (hardens) the metal so it scratches less for the customer.
On our custom pieces, after casting, we beat the surface with the burnishers to harden them. Especially the shanks of rings. This works great on sterling silver. Burnishing with the bent burr also can get rid of porosity.
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.
