One of my past custom clients just got in touch saying that his wife managed to cover her engagement and wedding rings with polyurethane- he said they’re entirely coated. She hid them away instead of dealing with the issue immediately, so they’ve been sitting for months. Ugh.
The rings are both cast 900 platinum, and the engagement ring has an unheated/untreated sapphire and diamonds. I’m thinking a soak in acetone (or other polyurethane remover?) should be OK for these materials, then perhaps a blast under steam or ultrasonic to get the remaining goo out of nooks & crannies?
But never having dealt with this issue before, I’d love some reassurance and/or advice on alternatives from anyone who has been there or has education in this matter. Thanks in advance!
