Customer Questions & Answers

  • Question: What is a diamond tester and how does it work?

    Answer: A diamond tester is a specialized tool designed to distinguish between real diamonds and simulants by measuring thermal conductivity. When the probe tip is placed on the gemstone, the device sends heat through the stone. Real diamonds absorb heat quickly, while materials like cubic zirconia do not. This functionality makes diamond testers critical for jewelers and collectors to confirm the authenticity of their stones.
  • Question: What is the difference between a diamond tester and a loupe?

    Answer: A diamond tester detects the authenticity of gemstones, while a loupe is a magnification tool that allows detailed inspection of the stone's quality and any inclusions. Using both together can significantly enhance the evaluation process: the tester confirms if the diamond is genuine, while the loupe helps scrutinize its clarity and cut. This combination is invaluable for anyone in the jewelry industry or for passionate collectors.
  • Question: Can this diamond tester be used on other gemstones?

    Answer: While the primary function of a diamond tester is to identify diamonds, it can sometimes distinguish between other gemstones that have similar thermal properties. However, results may vary, as some simulants can also give false readings. It's best used as a starting tool for vetting stones, and for more precise assessments, a jeweler's loupe or professional appraisal may still be necessary.
  • Question: What is a 30X and 60X magnification and when should I use each?

    Answer: The 30X magnification is suitable for general inspections of gemstones, allowing you to spot surface flaws and the overall quality. The 60X magnification, on the other hand, is used for a more detailed examination of inclusions, facets, and other intricate details. Jewelers and gemologists often utilize both magnifications depending on the depth of the assessment needed for the gemstone or jewelry piece.
  • Question: Is the diamond tester portable?

    Answer: Yes, the diamond tester is designed with portability in mind. Its lightweight and compact design make it easy to carry in your pocket or bag, allowing jewelers and hobbyists to take it anywhere, whether at trade shows, appraisals, or personal evaluations at home. This convenience ensures that you can always verify the authenticity of your gemstones at a moment's notice.
  • Question: How should I maintain my diamond tester?

    Answer: Regular maintenance of your diamond tester includes keeping it clean and ensuring the probe tip is free from debris or damage. You should store it in a protective case and avoid exposing it to extreme temperatures or moisture. By taking these precautions, you ensure that the device remains accurate and functions optimally, providing you with reliable results every time you use it.
  • Question: Can I use this tester for both loose diamonds and mounted jewelry?

    Answer: Yes, this high-accuracy diamond tester can be used on both loose stones and diamonds set in jewelry, provided that the probe tip can reach the stone. For mounted pieces, extra care is necessary to ensure the test does not damage the setting or surrounding stones. This versatility makes the tester beneficial for both professional jewelers and private collectors managing their jewelry collections.
  • Question: Is the LED light useful during testing?

    Answer: Absolutely! The built-in LED light illuminates the gemstone, which enhances visibility and allows you to inspect the stone's clarity better during the testing process. This feature is particularly useful in poorly lit environments or when evaluating smaller stones, ensuring that you can see every detail clearly, thereby improving accuracy in your assessments.
  • Question: What accessories come with the diamond tester?

    Answer: Typically, the diamond tester is accompanied by a protective case and may include a user manual or guide for optimal operation. Some sets may also feature additional tools such as a loupe for magnification. Having these accessories enhances the user experience by providing everything needed to effectively identify and evaluate gemstones right out of the box.
