Do lab grown diamonds pass a diamond tester?
Lab grown diamonds are real diamonds, of couse, they can pass a diamond tester.The composition and characteristics of lab grown diamonds and natural diamonds are exactly the same, they are essentially the same substance.
How do we distinguish them? At present, common instruments on the market are generally unable to distinguish them, and can only be distinguished by using professional instruments in testing institutions. It is precisely because of this that when diamond certification agencies such as IGI and GIA issue certificates, they must show whether they are lab grown diamonds or natural diamonds.This prevents some unscrupulous merchants from selling lab grown diamonds as natural diamonds, and this protects the interests of consumers.
