The pearls are very pretty (that s why I rated 3 stars), however, they did not come with a Certificate of Authenticity. Without the certificate, there s no certainty as to what grade the pearls are or from what place of origin they came. So it seems as if Pure Pearls doesn t want to stand by their product. - Pure Pearls Response: Dear AC'O, We are terribly sorry that your GIA Graduate Prepared Retail Appraisal was missing with the shipment. ALL of our fine pearl jewelry should be accompanied by our Retail Appraisal, Care Instructions, and other assorted documentation. I'm pleased that we were able to resolve the situation by sending you the missing Appraisal, and hope that you enjoy your pearls for many years to come. If you have any questions or concerns, please know that you can always reach me directly at: Ashley@purepearls.com for a quick resolution!
