Question

Any words of wisdom on repairing platinum jewelry? I’m retired and do some metalwork for the local jewelers. Mostly, I do small gold jobs for them when they are too busy to keep up. (I enjoy it, and it keeps my mind and hands occupied). A few times, I’ve been asked to repair platinum jewelry, resize a platinum ring, or add a platinum head to an 18K shank. I’ve refused these jobs because I have no experience working with this metal. Can someone give me some pointers?

Thanks,

The techniques for soldering platinum are identical to gold techniques. The difference with platinum is you work at a much higher temperature that’s actually safer.  Platinum will not oxidize, which enhances fusion. It’s a wonderfully malleable and ductile metal. It files and shapes easier than gold because it’s…
