Diamond tester and moissanite tester

for testing diamonds or moissanite.

Procedure for testing laboratory-grown diamonds:

The technology of the testing devices for purely laboratory-grown diamonds (ARI, SDS II) is not suitable for simulants such as zirconia or cubic zirconia and in these cases returns ‘diamond’ as the result. The conventional diamond tester “Diamondmate-A” (PDMT-A)" or the “Adamas” can help here, as it can identify cubic zirconia and colourless sapphires.

1st test step:
Therefore, test the stone in question in a first test step with the “Diamondmate-A”, the “Adamas” or Multitester III to ensure that it is indeed a diamond. If the tester has identified the stone as a ‘diamond’, it means that the stone is either a natural diamond, a lab-grown diamond or a moissanite.

2nd test step:
In a second test step using a tester for lab-grown diamonds (ARI, SDS II), you can then subdivide the natural diamonds from the lab-grown diamonds and moissanites.
