If you already saw this in the Jewelry Pieces forum, sorry for the double post. I only got one reply there.
I hope this question has not already been asked. I searched the forums, but I only found topics relating to melting old settings or other jewelry, and I understand the problems in that situation.
I'd like to use a 1-oz platinum coin (99.95% pure; gift from my dad) and a 1.0 ct round diamond (my mom's) to make an engagement ring. Local jewelers only offer store credit for the coin, but I want this metal to be in the ring. If the jeweler would normally start with platinum grain, melt it, and cast it, then why not start with a pure platinum coin? That should eliminate the problems of solders, other metals in a setting's alloy, and the unknown purity issue. Perhaps the issue is that it needs to be 950 or 900 platinum, and the jewelers cannot make their own alloy by adding pure ruthenium?
Anyway, I've exhausted local jewelers, and many who I found online give me the same answer. There are some willing to work with my platinum, but I would also like a tension setting. Unfortunately, I have yet to find the overlap of a jeweler willing to use my platinum who can also make a tension setting. I'm hoping someone here can help me find one.
Thanks!
