Quality Assurance Benchmarks highlight workmanship of semi-finished and finished platinum jewelry. These examples illustrate methods for evaluating the quality and durability of platinum prongs and settings.
Potential Problems and Engineering Features
In this example, a sales associate has sold a loose diamond and a platinum ring setting
This platinum setting is made using a process called die-striking. The prongs are cut away from sheet-stock by a die, assembled, and then oven-soldered. Once they are made, they are torch-soldered into the setting.
Real Life Consequences: This is a real story, but some details have been changed. A retailer designed and created a custom platinum setting for a 22.50 carat round brilliant diamond. The ring was hand fabricated using 90% platinum/10% iridium, which is among the softest and most malleable of all platinum alloys.
Real Life Consequences: The original ring’s fragile custom mounting is shown next to one made using the specifications for a secure setting. With a 22.5 carat diamond, a setting should minimize potential for loss.
