I am searching for a second hand ring and came across this one. I feel the person might be asking too much for a used ring. the platinum Solitaire ring is .37 ct VVS1 color G and its 20 years old. can someone tell me what price range it should be in? and since the ring is from 1996 it most likely does not have a laser engraved number on the stone, so it might be harder to see if it is an authentic Tiffany. please let me know if something looks suspicious in the photo. Thank you
