How is the stone guaranteed?
Most wholesalers will certify the stones they sell. The Gemological Institute of America (GIA) is the most common American institution for grading diamonds. They will authenticate and provide a grading report for each stone. This way, you can be sure that your diamond is exactly what the dealer says it is. If a stone is not certified, request to have one done, most respectable retailers and wholesalers, like Amgad, will be happy to provide this service. To further protect you, Amgad offers a 15 day, money back guarantee if for some reason the piece is not what you expected.
