Hi: New to the board and truly clueless when it comes to pearls. I have an old 17 inch strand of 7mm Mikimoto pearls handed down through my family since they were purchased by my great grandmother in the 1920s. They have been cared for and maintain their luster without yellowing or any blemishes. I took them to a jeweler for an appraisal and they told me they really had no monetary value because they were so old. She said they were AA+ and in excellent condition, but that they had more sentimental value and should be restrung. She then offered to buy them from me for $500.00. This doesn't sit right with me, but I have no idea. Do pearls lose their value or was this a con?
Thank you for any insight.
