I recently received an 18 inch pearl necklace that was given to me as a gift. The necklace is in a Mikimoto box and includes an official certificate of valuation. I have included a picture of the certificate which shows the dimensions of the pearls (6.5x7MM), the color (pinkish white), luster (excellent), quality (AA), clasp setting (18Kt yellow gold), and design number ( U 70318 A K).
I am looking to sell the necklace on eBay but I am rather unsure how much these go for. They paid $4,800 for the pearls in 2005 and have been kept in mint condition since. Any help would be appreciated!
