Best place to sell diamond jewelry in San Francisco. I had some old jewelry from an ex boyfriend that I wanted to turn into cash. Had a few necklaces, a bracelet and diamond stud earrings and shopped around quite a bit. I went to several pawn shop, that were total rip offs. Also went to a few other diamond buyers. The diamond buyers at Diamonds4cashSF were great. They offered me about 20% more, itemized my jewelry and were very easy to deal with. Got a check right away and was very happy. Great hours and perfect location. 1 min away from Powell bart station. Plus this is actually a great jewelry store, not just a one man show to take advantage of high gold prices.
