Customer Questions & Answers

  • Question: What is the Presidium Instruments Gem Tester II PGT II used for?

    Answer: The Presidium Instruments Gem Tester II PGT II is designed to accurately identify diamonds, Moissanites, and common colored gemstones. This precision tool utilizes Assisted Thermal Calibration (ATC) technology to deliver reliable results with ease. It's particularly useful for jewelers, gemologists, and hobbyists looking to differentiate between gem types quickly and efficiently. For instance, if you're comparing a diamond and a Moissanite in a retail setting, this tester will help ensure you provide your customers with accurate information about the stones.
  • Question: How does the Assisted Thermal Calibration (ATC) feature work?

    Answer: The Assisted Thermal Calibration (ATC) feature automatically adjusts the thermal readings based on the surrounding temperature of the gemstone being tested. This ensures higher accuracy and reliability in results, making it easier for users to identify gems without external interference. For example, if you're working in a warm environment, the ATC allows the tester to compensate for temperature fluctuations, which is crucial for proper identification of similar-looking stones like Moissanites and diamonds.
  • Question: Is the PGT II easy to operate for beginners?

    Answer: Yes, the Presidium Gem Tester II PGT II is designed with user-friendliness in mind. Its intuitive interface and straightforward instructions allow even beginners to quickly learn how to use it effectively. This makes it an excellent tool for new jewelers or hobbyists who may not have extensive training in gemology. A beginner could easily grasp its functions and accurately test gemstones right out of the box, ensuring they won't feel overwhelmed by its technology.
  • Question: Can the PGT II test all kinds of gemstones?

    Answer: While the Presidium Gem Tester II is highly effective for identifying diamonds, Moissanites, and some colored gemstones, it may not be suitable for testing all gem types. It is best utilized for stones with specific thermal properties. For instance, if you're working with sapphires or rubies, you may require additional tools tailored to those specific gems. This limitation means that jewelers should have a variety of testing equipment in their toolkit to cover different gem types comprehensively.
  • Question: What should I do if my PGT II is not giving accurate readings?

    Answer: If your Presidium Gem Tester II is providing inaccurate readings, consider checking the calibration and ensuring the device is properly maintained. Follow the calibration instructions provided in the user manual. Additionally, assess the environment you are working in, as factors like temperature can affect results. For example, if you’re in a highly humid environment, this could impact the performance. If issues persist, contacting customer support for troubleshooting guidance is recommended.
  • Question: Does the PGT II require any specific maintenance?

    Answer: Yes, the Presidium Gem Tester II requires regular maintenance to ensure accuracy. It's essential to keep the tester clean and store it in a safe, dry place. Regular cleaning of the tip with a soft cloth will help maintain its efficacy. Proper care helps your tool last longer and delivers optimal performance during tests. For instance, if left uncleaned, accumulation of dirt or residues can interfere with readings, leading to incorrect identification of gemstones.
  • Question: What is the warranty period for the PGT II?

    Answer: The Presidium Instruments Gem Tester II typically comes with a manufacturer's warranty that covers defects in materials and workmanship. The exact warranty length may vary by seller and region, so it’s prudent to check with the retailer from whom you purchase. This warranty is an added assurance that protects your investment, providing peace of mind should any manufacturing issues arise. Always keep your purchase receipt to facilitate claims under the warranty.
  • Question: Can the PGT II detect synthetic gemstones?

    Answer: The Presidium Gem Tester II is capable of identifying synthetic Moissanites and diamonds, as it measures thermal conductivity differences. However, it may struggle with some synthetic colored gemstones due to varying thermal properties. For jewelry professionals, understanding the limitations of the tester is crucial when handling synthetic stones. In practice, if you encounter a suspected synthetic stone, complementing your testing with alternative methods will provide more reliable identification.
  • Question: What accessories come with the PGT II?

    Answer: The Presidium Gem Tester II usually comes with a user manual, a calibration tool, and sometimes extra tips. These accessories not only enhance your user experience but also ensure that you can maintain and operate the device efficiently. For instance, having a calibration tool readily available allows for quick adjustments as needed, ensuring that you can trust the readings you obtain from your tester.
  • Question: Where can I buy the Presidium Instruments Gem Tester II PGT II in Montserrat?
