OK here is my question, i recently found a 29 diamond heart pendant necklace, it hasn't been in the ground long ,it looks kinda old but the diamonds are pretty big where do i sell it how do i sell it ? i was told that if there was paper work for this i cant sell it or it would hard to sell it ,,i have been told it is a very expensive piece of jewelry , my guess and others say at least two thousand dollars?
