GSI offers three types of comprehensive grading reports below. The differences are mainly in size. Each grading report comes with supplemental educational materials that help the consumer understand the report and their purchase.

All GSI Reports come with the following supplemental information:

Please note that all GSI Reports can be customized.

  1. The FDX, or "Full Diamond Examination," is an 8.5" x 11" document that comes with a clear plastic sleeve or can be folded to fit into a No. 10 envelope. The FDX is GSI's most comprehensive service for identifying and grading an individual gemstone or a piece of jewelry, including materials and side stones. It is the only GSI report that includes a Plotting Diagram.

    Integral to the report, on the back cover, is a section called "Understanding Your FDX Report." This feature offers an explanation for all the terms you will find on your report, such as "measurements," "clarity," and "shape/cut."

  2. The IDX, or "Intermediate Diamond Examination," is a 5" x 7" report that comes in a clear plastic sleeve (5" x 3.5"). The IDX offers the identical information as the FDX without the plotting diagram. A separate "IDX Report Guide" provides an explanation to the terms. It tucks neatly into the protective sleeve, along with a small version of "How to Take Care of Your Gems and Jewelry."

  3. The MDX, or "Modified Diamond Examination," is a handy credit-card-sized plastic document that measures 2.125" x 3.375". It offers basic 4Cs information and, depending on the item, will sometimes include measurements. A mini version of all the supplemental materials is offered with the MDX Report in an attractive vinyl case.
