What does Blue on diamond tester mean?
electrical-conductivity
THE SSEF BLUE DIAMOND TESTER For Blue and Potentially Blue Diamonds. With this instrument you are testing electrical-conductivity. By holding the diamond between two metal probes, you can determine whether or not it is electrically conductive. Type IIa diamonds are not electrically conductive.
What do the colors mean on a diamond tester?
If LED lights up to the red zone with three periodic bees, the stone being tested is a diamond. If LED lights up only to the green and/or yellow zone, then the stone is a stimulate or non-diamond. If the probe tip comes into contact with metal, the diamond tester will emit a continuous beep.
Is a diamond tester legit?
Diamond testes are probably the most accurate and reliable tools to check the authenticity of a diamond.

A cubic zirconia is a real cubic zirconia, but it is not a real diamond. There are a few types of stones that are used as diamond simulants, but cubic zirconia is by far the most common and the most realistic.
Can CZ pass diamond tester?
No. Cubic Zirconia (or CZ) does not have high enough electrical conductivity to pass. So, when you test a CZ with a diamond tester, it will not show as diamond. In fact, distinguishing CZ from diamond is one of the most important uses of thermal conductivity pen testers.
What are fake diamonds called?
A synthetic diamond is also known as a lab-grown diamond. Other names include a cultured diamond or a cultivated diamond. They are produced artificially, unlike natural diamonds formed in the Earth. Please note that our tests will not identify lab-created diamonds.
Are cheap diamond testers accurate?
How Reliable Are Diamond Testers? Diamond testers are one of the most accurate tools to check a diamond for authenticity. 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.
How can you tell if a blue diamond is real?
Most diamonds will reveal blue florescence under a black light; therefore, you’ll see a medium to strong color of blue, which means the diamond is real. If you don’t see the blue color and instead see a slight green, yellow or gray fluorescence then this usually indicates the gem is not a real diamond.
How can you test a diamond at home?
Lay the stone onto the dot with the flat side down. Through the pointed end of the diamond, look down onto the paper. If you see a circular reflection inside the gemstone, the stone is fake. If you cannot see the dot or a reflection in the stone, then the diamond is real.
