Diamond Tester Pen for Professional Jewelers (Black)

About this item

• Precautions and Tips: For accurate testing, avoid testing in windy conditions. Position the tip of the diamond tester professional perpendicular to the gemstone for accurate readings, observe the light pattern to determine the stone's authenticity. Always turn off the power after testing to conserve battery life
• Accurate Detection: Our diamond tester features a sophisticated sensor system that accurately identifies diamonds, with 5 lights for glass, 5-6 for jade, 5 for cubic zirconia, 7 for gemstone crystal, and 9 for diamonds and moissanite. It's designed to provide clear distinctions for various gemstones, ensuring you get precise results
• Metal Limitation: The gemstone tester is not intended for metal detection. When testing metals, the diamond tester pen will emit a rapid beeping sound due to the similar thermal conductivity between metals and diamonds. The Metal Alert helps you avoid false readings. High thermal conductivity items may mimic diamond readings and trigger the beeping sound. If you hear the beeping, adjust the probe to test only the gesmstone
• Seamless Shopping Experience: Our customer service team is available to help with any inquiries regarding product usage, ensuring you can maximize the benefits of our diamond tester.
• Easy Operation: Insert the battery, power on the tester. Adjust the indicator to the fourth mark (Otherwise, inaccurate results may be obtained), press the triangular metal plate at the back with your finger, and position the probe perpendicular to the gemstone. For diamonds, the light will jump to the ninth segment or higher (red light area) and emit beeps; for jade, it will light the fifth or sixth segment, indicating hardness without beeps. Always reset to the fourth mark before each test
• Package Contents: The diamond detector complete set includes a diamond tester pen, user manual, and testing platform for your convenience. Before you begin testing, please carefully read the instructions and tips in the user manual to help you achieve the most accurate results from the diamond tester (without 9V battery)
