Reports & Verification

Diamond & Gemstone Reports

A laboratory report brings examination results together in a form that can be read, retained, and shared. Its purpose is to describe the item and the findings within the selected service.

To understand a report, start with its full name. A diamond grading report and a gemstone identification report may answer different questions. Neither should be assumed to contain information that is not actually stated.

Diamond grading reports

Diamond grading reports describe applicable quality characteristics and identifying information. Depending on the report product, this may include weight, measurements, shape, color, clarity, cut-related information, finish, and comments.

When comparing diamonds, use the complete report rather than a shortened string of grades. Details outside the main grading fields may be relevant to your question.

Gemstone identification reports

Gemstone identification reports address the material examined and the conclusions issued within scope. Relevant findings may include the material identity and treatment information. Geographic origin should be treated as a separate result only when the report actually provides it.

Comments are part of the result

Comments can explain a limitation, clarify a finding, or provide context that does not fit into a short result field. Read them before deciding what a report establishes.

When sharing a document with a buyer or customer, keep those comments attached. Removing a qualification can change the meaning of the conclusion.

Reports and physical items

A report refers to an examined item. The connection between that item and a document should be considered through the available identifying information. Measurements, characteristics, images, and inscriptions may contribute to that comparison where present.

An online lookup helps check the report record. It does not physically examine the stone in your possession.

Reports and value

Gemological characteristics can inform discussions of value, but a laboratory grading or identification report is not automatically a monetary appraisal. If you need a valuation for a particular purpose, confirm which separate documentation is required.

Choosing the right report

Tell IDGL what information you need and how you intend to use it. Confirm the report product, eligible items, included results, and limitations before submission.
