  See-through test method: Place the lab grown diamond tabletop side down on a book or newspaper with black lettering and try to see the lettering through the lab grown diamond. This is because the refractive index of lab grown diamonds is very high, so if you encounter Moissanite, which also has a high refractive index, this method will not be able to distinguish.


  Use a 10x loupe to see whether the lab grown diamond is mono-refractive or birefringent. lab grown diamonds are mono-refractive stones, while moissanites are birefringent. If you look down from the table to the pavilion of the lab grown diamond with a 10x loupe, you can see that the prongs near the bottom tip are overlapping, or if you can see that the prongs near the bottom tip are overlapping from the kite surface at an angle, then it is probably moissanite, not lab grown diamond.


  Specific gravity liquid: The specific gravity of lab grown diamond and moissanite are not the same, so you can distinguish them by using specific gravity liquid, but only for unset stones. (The chemical composition of the specific gravity liquid is diiodomethane, which is highly toxic, so you should be especially careful in using it.)


  Fire method: burn the gemstone with a lighter, moissanite will appear slightly yellow, but after annealing, it will return to its original state, while the color of lab grown diamond will not change after the fire. But be careful, do not exceed 600 degrees, or the real lab grown diamond will oxidize. Unless as a last resort, generally do not try this method to avoid disputes.
