Can Diamond Testers Be Wrong. Diamond Testers are Not Perfect and there are many ways they Fail. The tip could be loose bent or worn down.
You could accidentally hit a prong. It is very hard at 925 diamond is 10 and it is highly refractive with an index of refraction of 26 - 27 diamonds. Unlike diamond simulants such as CZ or Moissanite lab-created diamonds will test positive when using a diamond tester.
However you should know that testers that rely on thermal conductivity can mistake a moissanite for a diamond because these two stones are very similar in the way they conduct heat.
Unlike diamond simulants such as CZ or Moissanite lab-created diamonds will test positive when using a diamond tester. This problem is solved by using a device that uses electrical conductivity to test stones diamonds and moissanites conduct electricity differently. It does have many similarities. The tip could be loose bent or worn down.
