When Official Jewel Box authenticates an item, a digital certificate will be produced, which can be shared via text, emailed, included in online listings and printed. Each authentication certificate is given a unique link, hosted on Official Jewel Box servers for buyer verification.

For businesses certificates will increase confidence while enabling listings to sell faster and for higher prices.

For private customers certificates offer peace of mind that a purchase was of legitimate quality.

All Official Jewel Box authentication certificates are easily searchable online to confirm the item was authenticated by Official Jewel Box. These links are clickable on the certificates themselves or by typing the url into your search bar, then adding in that certificates unique authentication code.

All certificates are issued in English language.
