A laboratory report records findings about a gemstone at a particular moment. It is evidence—not a guarantee, appraisal, or permanent identity card by itself.
What a report can establish
Depending on the service, a report may identify species and variety, natural or laboratory-grown origin, detectable treatments, weight and dimensions, and sometimes geographic origin.
Reports normally describe the submitted stone only. They do not guarantee legal title, ethical sourcing, future value, or seller conduct.
Choosing a laboratory
Use established laboratories with relevant colored-stone expertise, transparent methods, report verification, and a reputation appropriate to the transaction value.
The issuing laboratory matters more than a decorative certificate from the seller or an unknown appraisal company.
Verify before relying
Match weight, dimensions, photograph, report number, and identifying characteristics to the listing. Use the laboratory’s official verification system where available.
A report may be genuine but belong to a different stone. RealGem certificate records are designed to preserve the document alongside the listing and transaction history.
Key takeaways
- ◆ A report is not a valuation.
- ◆ Verify the report with the issuing laboratory.
- ◆ Match measurements and identifying details.
- ◆ Higher-value claims justify stronger documentation.
