Quality Assurance Benchmarks highlight workmanship of semi-finished and finished jewelry. Learn how to evaluate the quality of a platinum ruthenium peg setting installation into a 14K yellow gold mounting.

There are no tool marks or unfinished areas on the ring, including inside the setting.

The mounting is hallmarked 14 karat gold and 950 platinum ruthenium.

The solder joint between the round platinum ruthenium setting and yellow gold shank is complete, from inside the shank to the base of the setting, and at the top area of the shank.

The platinum ruthenium setting is counter-sunk into the top of the yellow gold shank, and solder flows completely around the base of the setting.

The setting is squarely aligned with the mounting.

The peg setting must have complete and even solder flow, from the bottom of the peg inside the mounting to the top of the mounting, and around the base of the platinum ruthenium setting.

Slightly countersink the setting to fit into a recessed area on the top of the mounting. This will allow for a complete flow of solder around the base of the setting, securing it for years of trouble-free wear.

Assemble using gold solder and gold soldering techniques.

The hottest part of the flame is just beyond the cone. Position the torch in the area just away from the joint and solder.
