For the inspection of synthetic diamonds, there are relatively mature equipment on the market. For consumers who don't know about diamonds, they can send them to the testing organization for re-inspection.

For diamond practitioners, vvs and some vs diamonds with good clarity also need professional testing instruments. For diamonds with slightly poor clarity, such as vs, si or below, it is generally possible to judge whether they are artificially cultivated diamonds according to the shape of inclusions in diamonds through a ten-fold magnifying glass.
