Certificate of Authenticity
You can purchase a certificate of authenticity for your winning items from Bidz.com!
Eligible items will show appropriate notification on the auction page: "Certificate Available at Checkout"
These certificates provide reliable details such as the identification, authentication, content and weight of the gems or precious metals contained in an item. Certificate will include an enlarged colored photograph which will show further identifying information. All gemological analysis for Bidz.com will be done at one of our highly qualified independent gemological laboratories.
During the check-out process, you will be able to choose a Certificate of Authenticity from the drop-down menu and then purchase it along with your items. The cost of the Certificate is $33 USD/per item.
Note: If you order a Certificate of Authenticity, it will delay the delivery of your order up to an additional 7 days. Certificates can only be cancelled within 24 hours of your processed payment and are non-refundable thereafter.
To avoid further shipping delays certificates may be shipped separately.
