Lightly touch the probe tip in the center of the gem stone. (Approximately 250mg of pressure) Hold tester perpendicular to the table of the gem for one second.5. If it's a simulation or non -diamond, nothing will happen. If it's a diamond, the buzzer will ring and the green light(diamond) will come on for about 6 seconds. If it's a moissanite, the tone will change and the light will switch from green to blue(moissanite) within 1/2 second.6. After the buzzer is first heard, you must continue to test for one second before you take the probe off the gem stone, this is because the test for diamond is done first. The test for moissanite is completed 1/2 second later.7. If the tone changes while you are removing the probe, you must retest because you may have contacted the metal findings while removing the probe.8.
