How to Use a Diamond Tester

Diamond testers are essential tools for anyone who deals with diamonds, whether it's in jewelry or as an investment. These tools help individuals determine whether a diamond is natural or synthetic, which is a crucial factor in determining its value. In this article, we will provide a step-by-step guide on how to use a diamond tester to ensure accurate results.
Step 1: Prepare the Diamond Tester
The first step in using a diamond tester is to prepare the device. Diamond testers are electronic devices that require batteries, so make sure that the batteries are fully charged before using the tester. If the tester requires calibration, follow the manufacturer's instructions to calibrate the device. Calibration ensures that the device is accurately measuring the diamond's properties.
Step 2: Clean the Diamond
Before using the diamond tester, it's essential to clean the diamond. Dirt, oil, and other impurities can affect the tester's accuracy, leading to false results. Use a clean cloth to wipe the diamond's surface and remove any dirt or oil.
Step 3: Turn on the Diamond Tester
Once the diamond is clean, turn on the diamond tester. The tester will take a few seconds to warm up before it's ready to use. During this time, make sure that the diamond is not touching any metal surfaces, as this can affect the results.
Step 4: Test the Diamond's Electrical Conductivity
To test the diamond's electrical conductivity, touch the diamond's surface with the tester's probe. The tester will emit a sound or light to indicate whether the diamond is natural or synthetic. If the diamond is natural, the tester will emit a continuous beep or light up. If the diamond is synthetic, the tester will emit a different sound or not light up at all.
Step 5: Test the Diamond's Thermal Conductivity
If the diamond tester has a thermal conductivity mode, you can also test the diamond's thermal conductivity. To test the diamond's thermal conductivity, touch the diamond's surface with the tester's probe while in thermal conductivity mode. The tester will heat the diamond for a few seconds and then observe how quickly it cools down. Natural diamonds conduct heat more quickly than synthetic diamonds, so if the diamond cools down quickly, it's likely synthetic.
Step 6: Interpret the Results
After testing the diamond's electrical and thermal conductivity, interpret the results. If the diamond passed both tests, it's likely natural. However, if the diamond failed one or both tests, it's likely synthetic. It's important to note that some synthetic diamonds can pass the electrical conductivity test, so it's essential to conduct both tests to ensure accurate results.
Diamond testers are essential tools for anyone who deals with diamonds, whether it's in jewelry or as an investment. By following these steps, you can use a diamond tester to accurately determine whether a diamond is natural or synthetic. Remember to prepare the diamond tester, clean the diamond, turn on the device, test the diamond's electrical and thermal conductivity, and interpret the results. With practice, you'll become more proficient at using the diamond tester and be able to make more informed decisions about diamonds.
