I traded in a one ct. diamond solitaire ring at Diamonds Int'l in St. Thomas, and they gave me a great price, especially considering it wasn't purchased from them. I did not have my appraisal with me, but no problem since they have gemalogists on staff. Purchased a beautiful 6.5 ct. tanzanite surrounded by 1 ct. of diamonds. A real beauty!!! It was a bit of a hassle sending the ring to NYC to be sized, but D.I. paid all expenses involved. Yes, you could go to any D.I.and they would accept your trade!
