Its alight it did however test a quartz as a diamond
Leads you to believe it will test precious stones and it does read them. But does not show what type of stone or quality of it .. and on a few occasions gave false readings. Does test diamonds as a diamond leaves no doubt that a diamond is real or cubix but not sure when it comes to a natural stone found wether they are or are not a diamond or quarts .

Did the job

It does the job.
Pro's: I tested my vintage & Antique jewelry and if you're patient & have a steady hand it works great. Cons: Difficult with tiny stones. If the tester touches metal it will buzz and is hard to test tiny stones. Also, there are NO instructions for testing results for other than diamond testing. I looked through other sales and found one seller that gave good info for what results to expect from other precious stone testing. This seller should include this info in their ads. I was a bit regretful at not having purchased from the other seller because of the good info and for the same price I would have gotten a 60x magnifier. All in all though, this tester does the job and i do recommend it.

Nice tester
The tester takes some time to get used to and I'm not sure if it is 100% accurate. It is a good tool to give you an idea if the diamond is real.
