We start by assembling the parts then we burnish (rub) the metal with tungsten pointers to compress and polish the platinum. We also use 1 mm strips of sand paper to polish and clean up the nooks and crannies.
After the prepolishing we attack the ring with soft brissel brushes and buffing wheels. This ring requires 6 hours of polishing.
Then we cut the seats for the diamonds and polished everything again.
The finished ring looks more like mounting flows off of the diamond then a mounting clamped on a diamond.
