Hi I have a diamond and moissanite tester I have a collection of moissanite and natural diamonds. I have a small problem as two of the moissanties repeatedly test as diamonds while the other moissanites test as moissanite and the certified diamond as diamonds.I have done the testing using the certified diamonds and identified moissanites as controls at least 10 times with the same result.What I doing wrong how reliable is the tester it is so messing with my head.
You may want to get another tester. The ones around $200 and up are usually accurate. Have a great day!
