I am not a jewelry expert but from my own personal jewelry that was appraised all of the markings identify the diamond karat weight, the 10K gold weight and the SDX is the brand/makers mark (some may say 'designer mark').


The SDX is the Simplex Diamond company. (SDX (SimplexDiam, Inc.). This is a company that seems to have started in 1979 (so your ring could not be any older than 1979) but seems to have closed and reopened the same company several times (according to the patent office).

I'm not sure anyone here can even give you an idea of the value - especially right now - as jewelry takes someone with gem knowledge and I doubt that anyone would venture an appraisal without having the ring in their hand.

You might take it to some jewelry stores in your area and ask what they will pay you for your ring - it will be low but you'll also know that you will probably not sell it for more than 100% more than they offer (IF they are interested, they may say $40-50) as rings are very difficult to sell and they know they may have this ring for several years.


You can also take your ring to a large pawn shop and see what they tell you. They will at least tell you everything about your ring (that matters) so you'll know how to offer it for sale.

Both of these places will give lower figures right now so think about doing more research when the world is in a better financial standing.

You could try to contact this company but I'm guessing they will not answer your letter.
