Platinum Cobalt Peg Settings: Installation and Removal

Solder must flow uniformly from inside the ring, up the peg and around the base of the setting. If a soldered peg setting assembly fails, it will cause the setting and the diamond to be lost during normal wear.

Laser welding the setting into the ring mounting will not properly secure it for long-term wear

Because the laser can only be aimed at visible joints and penetration is minimal, there’s no guarantee of a continuous bond through the assembly. Too often, laser welded peg setting assemblies fail, causing the setting and the diamond to be lost during normal wear.

Platinum plumb solder provides a colour match that’s superior to repair solders that do not contain platinum

Platinum soldering works best when a pallion of solder is placed over the joint. Do not heat it into a ball for transfer using a solder pick.

Store platinum plumb solders in dedicated, labelled containers. Leaving them exposed causes contamination.

Because platinum calls for high heat to solder, anneal and work, platinum-specific soldering blocks are required

This high-heat ceramic material block should only be used for platinum soldering projects. Using it with other metals can lead to contamination if it is used with platinum.

The ceramic material is stable. Thermal expansion of the block will be minimal.

The surface of the block is heat-reflective, which helps the heat to intensify sufficiently for the project

The block is reversible and can be modified to meet specific needs. This technician created slits in the block with diamond wheels. They hold the piece in the desired position.
