AGS members are respected leaders in the jewelry industry, and long-term members of your community. Your satisfaction is important to them because they know that, to build trust and confidence, they must provide you with the very best service and information available. Their success is enhanced by your satisfaction. When you shop for diamond jewelry or for a very special diamond, the first thing to look for is the firm's membership in the American Gem Society. Diamond grading is a highly specialized field, but it doesn't have to be mysterious.
Many consumers can distinguish between diamonds that are at extreme ends of the scale.
True, when the calls are closer, it takes a trained professional grader to make the distinction. Yet these distinctions can represent considerable differences in cost to you, the consumer. AGS members know that customers want to understand all the factors that influence the value of the jewelry they buy. For this reason, the American Gem Society has developed the AGS Diamond Grading System. Each factor is evaluated on its own 0 to 10 scale.
