Product Description: - Includes: 1 x Diamond Tester, 1 x 9V battery, 1 x 40X Jewelers Loupe, 1 x Protected leather bag, 1 x Texting Platform Precautions: - Do not wear gloves while operating the tester and avoid detecting metal. It is recommended to measure in calm wind conditions with an operating temperature between 10-35 degrees Celsius and humidity below 80%. When testing a diamond, ensure your right index finger is in contact with the metal panel on the back of the tester. Remember to turn off the power after testing to save battery. Place the 9V battery in the device and turn off the power after each use. Turn on the corresponding number of lights for indoor temperature and diamond weight. If unsure, set 4 lights on the scale. When testing diamonds, there is no need to adjust the switch. - Novice users should set 4 lights on the scale, while experts should set the initial value based on temperature, object size, and the device's table. The equipment measures temperature and transfers energy, so ambient temperature and object size can affect results. Use the diamond discriminator probe to make 90-degree contact with the object being measured and observe the indicator light changes. Apply some pressure to ensure full contact with the diamond surface. If unsuccessful, repeat the process. Test Result Analysis: - If the lights are equal to or greater than 9 and there are sounds, it is a genuine diamond. If the lights are less than 9 and no sounds are heard, it is not a diamond. Lights at 7 or 8 indicate a true crystal, while lights at 6 or 7 suggest a genuine jade. Lights at 4 or 5 indicate glass. Do not test metals or wear gloves. Note that a moissanite tester will classify moissanite as a diamond. 40X Mini Magnifier: - Item Type: Mini Microscope Pocket Magnifier - Magnification: 40X - Battery Type: 3 x LR927 Button Cell - Item Size: 2.5 x 4.5cm / 1 x 1.7inch - Features an intuitive design for easy use, with real diamonds emitting sounds and lights equal to or greater than 9. Fake crystals like cubic zirconium (CZ), crystal, and glass will not produce sounds and will have lights less than 9. This diamond selector tester ensures quick, precise, and safe diamond testing without causing harm to the stones. Adjust the Level Meter Lamp to light up to 4 after powering on. The 40X LED magnification allows for inspection of gems, coins, antiques, stamps, and more. Note that the battery temperature should be above 10 ℃, and the device cannot test metals to conserve power.
