Here at Berganza, there are many things we take into consideration when evaluating our antique step cut diamond rings. They are often very valuable, so we take great care in the process of evaluation. First of all, we pay close attention to the step cut diamond in order to determine its value. If you have any authentication (such as proof of purchase, proof of designer) this can increase the value of your vintage step cut diamond jewellery. Antique step cut diamond jewellery is incredibly valuable, and we are committed to conducting accurate assessments on each piece that passes through our doors.
