Diamonds will often be received that are clearly over- graded. Even with diamonds shipped with independent reports, the accuracy of the grades may be in question. If you are the salesperson representing the accuracy of the weight and the grade of a stone, it is your reputation that’s at stake. The buyer is depending on you to represent it accurately, and if this is not done to his or her satisfaction, a lost sale or a merchandise return may occur, as well as damage to your reputation.
