Product Details
- ACCURATE DETECTION : Our professional diamond tester pen (a reliable gem tester) features a sophisticated sensor for precise gemstone identification (Diamonds/Moissanite: 9+ lights + beeps; Jade: 5-6 lights; Crystal/Glass: 5-7 lights). (Jewelry-Only Detection – Not for metal/gold or gold testing kit use)
- STANDARD OPERATION : Insert battery (Gently press the wire and the cables to hold battery will secure it in place) → Power on → MUST preheat 30s (critical) → Adjust indicator to 4th mark (do not skip) → Hold back metal plate → Probe 90° perpendicular to gemstone. Reset to 4th mark before each test
- METAL DETECTION NOTE : Not for metal/gold or gold testing kit use – metal has similar thermal conductivity to diamonds (normal beeping, not a defect). Consistent with title "Jewelry-Only Detection"
- PACKAGE CONTENTS : Diamond tester pen + user manual + 9V battery + testing platform. Read the manual first to maximize accuracy with your diamond detector
- PRECAUTIONS : Avoid windy/cold conditions (15-25℃ recommended); Keep probe perpendicular to gemstone; Turn off power after using this diamond checker
- SEAMLESS SHOPPING EXPERIENCE : Useful usage guidance for this diamond tester and gem tester is available via included resources. Note: Only valid for gemstone testing—non-diamond items cause incorrect readings
- VIDEO GUIDE INCLUDED : Step-by-step operation & troubleshooting video covers preheating, calibration, perpendicular alignment, solves 90% of usage issues. Skipping any required steps may lead to inaccurate detection results
- BATTERY INSTALLATION WARNING : Ensure the 9V battery is installed with correct polarity and properly seated in the battery compartment. Otherwise, the device may fail to power on. For details, please refer to the instruction manual

Customer Questions & Answers
-
Question:
What is a diamond tester, and how does it work?
Answer: A diamond tester is a handheld device specifically designed for identifying diamonds and distinguishing them from other gemstones. It works by measuring the thermal conductivity of the stone. Diamonds have a unique ability to disperse heat quickly, which is why the tester produces a specific reading for diamonds. This is crucial for jewelers or anyone in the gemstone industry to confirm the authenticity of diamonds before purchase or sale. -
Question:
Is this diamond tester suitable for both diamonds and other gemstones?
Answer: No, this professional diamond tester is specifically designed for jewelry-only detection, meaning it is optimized to test diamonds. It delivers accurate results when testing for diamonds but may not be effective for other types of gemstones. For jewelers who primarily deal with diamonds, this focus ensures more precise and reliable results, which is essential when assessing the value of jewelry pieces. -
Question:
Can beginners effectively use this diamond tester?
Answer: Yes, beginners can effectively use this diamond tester. The design is user-friendly, often featuring a simple on/off switch and indicator lights that guide the user during the testing process. Additionally, the clear instructions provided make it accessible for anyone looking to verify their diamonds. This is particularly advantageous for hobbyist jewelers or individuals wanting to assess their personal collections. -
Question:
How accurate is this diamond tester in its readings?
Answer: This diamond tester offers high accuracy in its readings due to advanced technology used in its design. It minimizes the chances of false positives or negatives, which is critically important in professional settings. With high precision, jewelers can confidently determine the authenticity of diamonds, reducing the risk of losses during valuation or sales. -
Question:
What types of diamonds can be tested with this device?
Answer: This diamond tester is capable of testing various types of diamonds, including natural, synthetic, and even some enhanced diamonds. However, it is essential to note that the tester is primarily designed for traditional diamonds. Therefore, while it may indicate the presence of diamonds, consulting additional tools for unique categories like colored diamonds can provide a more comprehensive assessment. -
Question:
Is this diamond tester portable?
Answer: Yes, the diamond tester is designed to be lightweight and portable, making it easy for jewelers to carry it around. This portability allows for convenient testing in various environments, whether it’s in a retail store, at trade shows, or during home appraisals. Its compact size fits comfortably in a bag or pocket, which is advantageous for professionals always on the move. -
Question:
What are the key features of this professional diamond tester?
Answer: Key features of this professional diamond tester include a high accuracy reading, a fast response time, and a compact design. Many testers also feature a visual and audible alert system to indicate a successful detection of diamonds. These features enhance usability for professionals, ensuring they can quickly and confidently assess gemstones under various conditions. -
Question:
Can this diamond tester be used for other jewelry besides diamonds?
Answer: This diamond tester is specifically tailored for diamond detection and is not suitable for testing other types of jewelry. While there are testers available that can check a range of gemstones, this model focuses solely on diamonds to ensure maximum accuracy. Jewelers might want to use an additional gem tester if they frequently handle multiple types of gemstones. -
Question:
