Authenticity assurance: Reduces risk of buying misidentified or enhanced stones.

Peace of mind: Independent verification from a lab-backed report.

Market confidence: Increases buyer trust and can command higher prices.
Faster sales: Clear documentation speeds transactions, especially for online marketplaces and auctions.
Transparency: Reduces disputes and returns by clearly disclosing treatments and attributes.

Compare the lab’s report number and details with the physical stone and any seller claims.
Use the treatment and origin notes when pricing or listing the stone.
Provide photomicrographs and report excerpts in listings to increase buyer trust.
Keep the original report for insurance and resale; obtain a re-check before major resale if several years pass or if stone is recut.

Some origins or treatments may be inconclusive without advanced tests (e.g., certain diffusion treatments or origin determinations).
Report conclusions depend on available instruments and sample condition; labs may differ in wording and strictness.
Recutting or repolishing can change some reported attributes.
