This diamond tester is a great deal with the jewler scope and rechargable 9v included. It is good for diamond, crystal, jade, & glass. You will love the fact it actually comes with its kit, cover cases, a battery, and a lil Flashlight/UVLight Microscope. The tip of the pen is the size of a sewing needle so it can detect on very small stones using a steady hand.

This device is very helpful to separate the jewelry. It is a good tool to have around the house, easy to check types of stones you may come across. If even slightly tilted, it will give no reading or alert as diamonds, so it cannot test silver.

Best For jeweler: Stillcool Fake Jewelry Tester

The stillcool fake jewelry tester should be able to handle its purpose and duties with ease. Sometimes lab diamonds have tiny little scraps of metal left over from the process. This is a fun little tool to identify your diamonds or maybe not diamonds. It is battery-powered by a standard 9v battery (not included), and the package comes with a leather pouch case, testing platform, user manual and accurate diamond tester pen. It makes a different noise if touched to metal or glass. It is almost easier to test them while holding rather than using the stone holder.

The metal sensitivity beep may go off a couple times if your diamonds are "lab diamonds" because sometimes lab diamonds have tiny little scraps of metal left over from the process. This will use an electric current to test rather than a thermal signal. The probe to heat up until another indicator is lighting up. The volume is very narrow with sound. It can be a bit cumbersome at times.
