Here at Berganza, there are many things we take into consideration when evaluating our sugarloaf sapphire rings and jewellery . They are often very valuable, so we take great care in the process of evaluation. First of all, we pay close attention to the sugarloaf stone 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 sugarloaf stone ring or jewellery piece. Antique sugarloaf sapphire jewellery is incredibly valuable, and we are committed to conducting accurate assessments on each piece that passes through our doors.
