The diamond selector has a built-in calibration disc and glass testing disc. The 0.6 mm probe accurately tests diamonds as small as 0.02 ct. The clear and intuitive analog scale of gem tester machine displays measurement results in real time. The diamond detector machine can test a wide range of gemstones, including glass, jade, crystal, and emeralds.
Simulated scale, high-precision probe pen
- The diamond tester is equipped with a clear and intuitive simulated scale, making operation simple and readings readily available for quick result interpretation.
- Adopt a retractable thermoelectric probe head design, diamond selector can adjust contact pressure during testing to ensure a constant and stable contact between the probe head and the gemstone, effectively reducing error.
- The finest 0.6 mm probe head of gem tester machine can accurately detect diamonds as small as 0.02 ct, suitable for identifying tiny gemstones.
Calibration dial, built-in metal alarm buzzer
- A built-in metal alarm buzzer sounds when the probe makes full contact with the gemstone, helping users confirm the testing status and further enhancing the reliability of the diamond tester machine.
- The electronic diamond tester comes with a built-in calibration dial and glass inspection dial for convenient comparison and calibration at any time, ensuring measurement accuracy.
- The gemstone tester pen supports power from two AA batteries or an external adapter, offering flexibility and suitability for various testing scenarios.
Application
The diamond tester pen is primarily used for quickly identifying the authenticity of diamonds. By detecting the thermal conductivity of gemstones, it differentiates between natural diamonds and imitation diamond materials. It is widely used in jewelry retail stores, pawnshops, jewelry processing plants, appraisal institutions, and for personal collection testing. It can also assist in identifying common diamond simulants such as crystal, jade, gemstone.

Q1: What is a diamond tester?
A1: A diamond tester is a portable testing tool used to quickly identify the authenticity of diamonds. It is commonly found in jewelry stores, gemological laboratories, and private collections. Gemstone detector  is typically designed based on the physical property of diamonds, which have extremely high thermal conductivity (or, in some models, high electrical conductivity). A metal probe contacts the surface of the gemstone, quickly determining whether the object being tested is a diamond.
Q2: What does the "beep" sound from a diamond tester mean?
A2: When a diamond detector emits a continuous or distinct "beep" sound, it usually indicates that the thermal conductivity (or electrical conductivity) of the tested gemstone has reached the threshold for diamond identification, and the diamond detector machine determines that it is likely a real diamond. If there is no sound or only a low-level warning, it generally indicates that the gemstone is glass, zircon, or other diamond-like materials. However, it should be noted that some high-quality imitations (such as moissanite) may also trigger an alarm on some gem tester machine, so other testing methods should be used in conjunction with the tester for a comprehensive assessment.
Q3: What is the purpose of a diamond tester?
A3: A diamond checker can quickly and initially distinguish between diamonds and diamond imitations, helping users improve their judgment efficiency and reduce the risk of misjudgment in non-laboratory environments. The gem tester machine is easy to operate and has a fast detection speed, making it suitable for daily screening and on-site testing. It is more often used for initial screening and auxiliary judgment.
Tips: How to use a gem tester?
When using a gem tester, first clean the gemstone surface and isolate it from skin and metal. Turn on the gem tester machine and complete the calibration. Then, gently touch the gemstone surface vertically with the probe, maintaining stable pressure. Observe the indicator light, scale, or beep to determine the result. To improve accuracy, you can test multiple times at different locations. The gemstone testing equipment are suitable for quick preliminary identification and cannot replace professional appraisal.
