Each piece of diamond jewelry from EinStein Diamant is delivered with a guarantee certificate that complies with international standards.
The certificate includes a photo of the item along with all specifications related to the jewelry and the gemstones it contains. In the event of an exchange, return, or repair, the item must be sent back together with the certificate.
Why Is a Diamond Certificate Important?
Our certificates are printed on durable plastic cards (similar to a credit card) and contain not only detailed specifications but also a high-quality image of your jewelry piece.
If you would like a different type of certificate – such as a GIA or HRD grading report – the certification process requires approximately 5 business days, and the associated costs of around €150 must be covered by the customer.
Please note: This additional service is non-refundable in case of a return or cancellation.
However, all relevant details regarding our diamonds are included on the enclosed EinStein Diamant certificate and can be independently verified by a jeweler of your choice.
