Do lab grown diamonds pass a diamond tester?

Yes! Lab grown diamonds test positive on a diamond tester because they're made of crystallized carbon, just as mined diamonds are. Although, because some HPHT diamonds may carry impurities (although unnoticeable to the naked eye), there is a chance they could test as moissanite or non-diamond.

Are lab diamonds graded?

Lab diamonds receive grading reports from independent gemological organizations on the 4Cs: Cut, Color, Clarity, and Carat Weight. Just like in mined diamonds, lab diamonds will exhibit variations across the 4Cs and range from poor to superlative quality. Not all lab diamonds are perfect, colorless, and flawless!

How does Gia test a laboratory grown diamond?

When GIA receives a stone for grading, we test it to determine its identity as well as to detect potential treatments. Methods of analysis include observing inclusions and florescence and phosphorescence. If a diamond is found to be laboratory-grown, GIA issues a Laboratory-Grown Diamond Report.

Can a diamond be grown in a lab?

Lab-grown diamonds are now becoming a popular alternative for many people, since they can have the same beauty and properties as a mined diamond and are often more affordable. Whether you are considering a lab-grown or natural diamond, know its identity and quality by purchasing a stone with a GIA Diamond Report.

Do you need IGI for lab created diamonds?

Diamonds sellers benefit from the lower cost, but not necessarily the end consumer. For natural diamonds, we don’t recommend the IGI because the grading is lax and not as consistent as the GIA. Even though GIA has now full certificates for lab-created diamonds, there aren’t that many of them.

Which is the best certification for lab created diamonds?

Overall, the best certification for lab-created diamonds is the IGI, because they give specific gradings for qualities like Color and Clarity. The GIA has started fully grading lab-created diamonds recently as well, however, those are much harder to find. Diamond certificates across the different grading entities are not equivalent.
