Sergio was so polished and profoundly forthright, plus his impeccable BBB rating, that I felt confident I made the right choice. Our deal is closed with my genuine and complete satisfaction. I look forward to working with Sergio and his staff again in the future!


Sergio was a great help to me. I highly recommend Jonathan’s Diamond Buyer to anyone looking to sell precious jewelry and especially diamonds.They were courteous, quick, and easy to work with.
