What qualifies the LAPIS as the best diamond tester pen? In addition to its light weight and compact features, the LAPIS diamond testing pen requires a simple test procedure only, and the results are indicated by different colored LEDs in the Results Window. It’s just simple and clear!
What’s more, the distinctive sound feature of the LAPIS diamond tester pen makes it possible to differentiate metal, diamond and moissanite with different beep patterns, even without looking at the Results Window.
Green LED
Yellow LED
RED LED
Blue LED
When the green LED lights up with a continuous beep, it means it is a diamond.
When yellow LED lights up, accompanied by a slow and intermittent beep, a moissanite is identified.
If the red LED lights up, the gemstone you tested is a simulant.
If metal is detected, the blue LED will light up together with a fast intermittent beep.

More about LAPIS ONE diamond testing pen – FAQs:
-
Why I am getting inconsistent results?Gemlogis testers require a certain level of user experience to handle properly: Make sure to clean the probe tip and remove oxidation Make sure to clean the surface of the gemstone to remove any grease and dirt Make sure the gemstones are at room temperature (remove from body/pocket to let it cool down) Make sure to point the probe tip at a perpendicular angle against a flat surface of the gemstone Make sure to allow the gemstone to cool down between consecutive tests Make sure to test different spots on the surface of the stones, due to the impurities on the stones, it may affect the results.
-
Why does moissanite indicate as diamond on some occasions?In some instances there may be a disproportional allocation of silicon carbide located on a moissanite; therefore, performing several tests on different spots (including the girdle) of the gemstone is recommended.
-
Can Gemlogis thermal testers detect uncut raw/uncut stone?Yes, as long as the stone has a clean & flat surface.
-
Will the size of the gemstone affect the test result?Yes. Smaller stones conduct less heat from the probe tip. Hence, the reading indicated may be slightly lower.
-
Why do blue diamond & black diamond indicate as moissanite or metal?Blue Diamond is a semiconductor due to the substitution of boron impurities in place of carbon atoms. Black Diamond is substituted with graphite or iron inclusions. Both blue and black diamond will indicate as moissanite or metal on the tester.
-
Why do I sometimes hear intermittent beeping when testing gemstones?Whenever the probe tip touches a metal surface, an intermittent beep will sound. This is only applicable to mounted gemstones.
