Quality Assurance Benchmarks highlight workmanship of semi-finished and finished jewellery. Learn the benchmarks for evaluating the quality of platinum jewellery that was furbished after wear using burnishing and light buffing techniques.
Potential Problems and Engineering Features
This platinum ring was an ideal candidate for burnishing followed by light buffing. Prior to finishing, it had nicks on the shank, and light scratches on all surfaces typical of daily wear over many years.
Although the dimensions of this platinum ring are substantial, burnishing rather than filing or using abrasives is a better method to prevent unnecessary removal of metal.
Platinum can be burnished either by hand or through the use of rotary tools. The devices shown below are used for hand burnishing.
Platinum can be burnished using rotary burnishers mounted in a flexible shaft or a micro-motor handpiece. These tools work well in a variety of applications.
