Lesson 21 · Diamonds & Engagement Rings · 34 seconds
Three checks before trusting a diamond report
A genuine report online does not prove the stone in front of you matches it. Verify the number on the issuing laboratory's official website, read whether the diamond is natural or laboratory-grown, and compare the measurements and quality information with the listing.
What this lesson shows
Check the report, then match the stone.
Generic icons walk through three checks: verify the number on the issuing laboratory's official website, read whether the diamond is natural or laboratory-grown, and compare the measurements and quality information with the listing. No real report, seal or number is shown.
