How To Read Your Gemstone Report

A simple guide to understand report numbers and gemstone details.

Key Sections of a GRI Gemstone Report
1. Header & Verification Details
Report Number: A unique alphanumeric code assigned to your specific testing event. You can use this number on our website’s online report verification database to confirm the physical report matches our official laboratory records.

Date of Issuance: The exact date the testing was completed. Because gemstones can be recut, treated, or altered at any time, findings reflect the state of the stone at this specific moment.

2. Physical & Optical Characteristics
This section details the primary measurable parameters used by gemologists to identify stone species:

Object / Description: Identifies the type of article submitted (e.g., Loose Cut Gemstone, Mounted Ring, Bead Strand).

Weight: Measured in Carats (cts) for loose stones or Grams (g) for larger items/jewelry.

Dimensions: Recorded in millimeters (Length × Width × Depth) to document the stone’s precise scale.

Cut & Shape: Describes the structural geometry (e.g., Oval Mixed Cut, Cushion Brilliant, Round Cabochon).

Color: Documents the primary hue and tone observed under standard laboratory daylight lighting (e.g., Blue, Pigeon Blood Red, Deep Green).

3. Gemmological Conclusion (The Core Finding)
This is the most critical part of the report, containing two vital lines:

Species: The overarching mineral group to which the stone belongs scientifically (e.g., Corundum, Beryl, Quartz).

Variety: The specific commercial or gemological name within that mineral family (e.g., Blue Sapphire, Emerald, Amethyst).

4. Comments & Treatment Disclosures
This section explicitly discloses whether any treatments, enhancements, or synthetic origin indicators were detected during testing:

Natural vs. Synthetic: Clarifies whether the stone was grown by nature or synthesized in a laboratory.

Treatments: Discloses common enhancements such as heat treatment, fracture filling (oiling/glass filling), or color irradiation. If no indications of treatment are detected within standard testing limits, it will be noted accordingly.

5. Specimen Photograph & Security Features
Specimen Image: A high-resolution reference photo of the tested stone or jewelry piece. Note that photos are approximations for visual identification and may vary slightly in scale or color saturation due to lighting and printing.

Security Elements: Includes Embossed GRI logo above the signature(A embossed seal to prevent document tampering or counterfeiting), Website QR code to verify the certificate from the website.
