Established in New York, DGS is a gem certification and appraisal institute renowned for its quality services, extensive experience and know-how.

Ten years ago, only the diamond dealer was using gemological reports. Today, consumers in general have become more demanding and quality conscious about the products they buy. A jewelry buyer seeking an explanation of why two similar diamond rings are priced $1,000 apart will not be satisfied with being told simply that one is a 'better' diamond. He or she will want to know why it's better. Today's jewelry consumers are more familiar with the 4C's than their parents. Jewelers now consider supplying such information as an integral part of any sale and modern retail training programs stress the importance of providing independent gemological reports for gems and jewelry in addition to educating the consumer.

All this has led to an increase in demand for reliable grading or appraisal reports from credible organizations such as the Gem House International (DGS).

Jewelers, retail stores, insurance companies, internet sales organizations, catalogue companies (mail order), accounting and securities firms and consumers are relying on the DGS reports.

Today the majority of good quality gem and jewelry items are sold with gemological reports. Besides exceptional stones, a gem has no name, no history. The user doesn't know where the stone was found, who extracted it, who polished it, or the name of the dealer. The only document that travels around the world with the gem is the Gemological Report.
