The last picture is half an “estimate” of JUST the diamond. It was bought from a jewelry store going out of business. The band was $500 and the diamond itself was estimated at $4,000, but we got a discount because of the close down. Together, for the set I’m asking $2,500. I don’t mind having it appraised but it’s $300 to have it sent off and I would need that as a down payment.
