20-30 bucks,sometimes less on Amazon.Better pictures needed, yours are out of focus. Clasp appears to say 14k, but out of focus so cant be positive. do an acid test to be sure it is gold, acid test kitss are not expensive.
Did you test it with a magnet?I don't know if you can tell from the pictures but on every link it looks like the opposite side is gold one straight line going back and forth zigzagging and the other part doesn't look like gold I'm so confused View attachment 2034859 View attachment 2034860 View attachment 2034861 View attachment 2034862 View attachment 2034863
Brass is not magnetic as well. I would get an acid kit to test your gold if you are going to want to know if the jewelry you find is precious metal. I have found rinks stamped 14k that wouldn't pass 10k test.Not magnetic
