IGI Certificate Upgrade

Optional IGI Certificate (+€30)

Every piece of jewelry comes with a Sternvoll Certificate of Authenticity as standard. If desired, you can also add an independent certificate issued by the International Gemological Institute (IGI).

As this requires examination and certification by IGI, the delivery time will be extended by approximately one week. If you would like to receive your jewelry as quickly as possible, simply leave this option unselected.
