Can diamond testers be wrong?
Can diamond testers be fooled?
You can have a stone that’s not a diamond beep just like a diamond.
In fact, a lot of jewelry stores and customers in the last ten years have probably bought diamonds that weren’t real, and never knew it!
Likewise, you can test a genuine diamond in a ring, and have it buzz like it’s not a real stone.
Diamond testers are not perfect, and there are many ways they fail:
- The battery inside the unit may be dying
- You could accidentally hit a prong
- The so-called diamond could be a Moissanite
- The tip could be loose, bent or worn down
Maybe the tester got wet? A little spilled coffee?
Maybe the batteries were corroded?
Maybe you’re pushing too hard on the tester, or you have it bent at an odd angle…
You just never know!
Often I’ll test a stone a couple of times just to be sure. And if the stone is questionable, I’ll probably check it with 2 diamond testers just to be positive.
Because a faulty or wrong reading could cost you thousands!
Moissanite reads like a diamond on old testers. Moissanites are man-made diamond look-a-likes that started showing up on the market about 20 years ago. These stones actually did test positive for a diamond on testers that the jewelers had.
Many stones raised a few eyebrows because they didn’t look quite right. Many jewelers would loupe the stones, look at the brilliance and light distribution and really debate if the stones were real or not. The tester said it was, but their appearance made them doubt the reading.
Plus, these new Moissanite stones weren’t as white as most diamonds were (they are now). They had a yellowish tint to them which helped raise more concern. I remember customers trying to sell these created diamonds to us as natural diamonds…
And I’m sure a lot of jewelers at that time unsuspectingly bought them and then resold them as well.
Only after reading about the up-and-coming Moissanites, what they were, and how they needed a different diamond tester to accurately read them did jewelers order them in. Regular testers tested stones for thermal conductivity (the transference of heat). The new diamond/Moissanite testers test for electrical conductivity. This separates the diamonds from the Moissanites.
It really was a scary thing!!!
Diamond testers COULD be fooled!
The stone could be a Moissanite, a diamond or something entirely different.
You could have a Moissanite in your ring right now and never know it!
Unless your local jeweler has an up-to-date diamond tester that also tests for Moissanite, you could be in for a little surprise.
Both kinds of diamond testers are on the market today. If you’re buying a stone or selling a stone, it may be wise to have it tested. Ask them if their tester accurately identifies Moissanites. Moissanite stones are NOT the same price as genuine diamonds (see Moissanites HERE on Amazon). They are usually about half the price.
You could buy a tester for yourself if you’re questioning your stone, or questioning the purchase or even the jeweler.
Cheap testers, that test for only diamond, run around $15 and up. Testers that also test for Moissanite might run up to $100. But, when we’re talking about stones that could be in the thousands, it’s a small price to pay for peace of mind.
