Customer Questions & Answers
-
Question:
What is the Presidium Instruments Gem Tester II PGT II?
Answer: The Presidium Instruments Gem Tester II PGT II is a professional-grade tool designed for accurately identifying diamonds, moissanites, and a variety of common colored gemstones. It utilizes advanced thermal conductivity technology, allowing gemologists and jewelry enthusiasts to distinguish between genuine stones and synthetics effectively. This tool is especially valuable for jewelers seeking to verify stone authenticity without damage. For instance, when assessing a ring's center stone, the PGT II can quickly provide results, ensuring informed purchases and sales. -
Question:
How does the Assisted Thermal Calibration (ATC) feature work?
Answer: The Assisted Thermal Calibration (ATC) feature of the PGT II enhances its accuracy by automatically adjusting to surrounding temperature changes. This ensures reliable readings regardless of environmental variations, which is crucial when testing stones under differing conditions. For example, if you're assessing a gemstone in a warm room, ATC compensates to ensure that the thermal conductivity measurements remain reliable. This makes it a perfect tool for professionals working in varying climate conditions. -
Question:
Can the PGT II differentiate between diamonds and moissanites?
Answer: Yes, the PGT II is specifically designed to distinguish between diamonds and moissanites with high precision. While both gemstones can appear similar, their thermal conductivity properties differ. The PGT II measures these properties, allowing gemologists to generate conclusive results efficiently. When you're appraising jewelry that may contain either stone, this tester offers peace of mind through its accuracy, helping to prevent costly errors in evaluations. -
Question:
Is the Gem Tester II suitable for beginners?
Answer: While the PGT II is a professional tool, its user-friendly interface also makes it accessible for beginners in gemstone identification. With step-by-step instructions and a clear display, new users can learn how to operate the device and interpret results quickly. Whether you're a hobbyist starting a collection or a beginner helping friends appraise their jewelry, the ease of use combined with its reliability makes it an excellent choice for all experience levels. -
Question:
What types of gemstones can the PGT II identify?
Answer: The PGT II is capable of identifying a range of gemstones including diamonds, moissanites, sapphires, rubies, and emeralds, among others. Its design caters to both natural and synthetic stones, providing an extensive testing capability. For those involved in jewelry-making or gemstone trading, this versatility allows for efficient sorting and decision-making when dealing with multiple stone types in various settings. -
Question:
Does the Gem Tester II require any special maintenance?
Answer: The PGT II requires minimal maintenance to ensure long-term accuracy. Regularly checking the battery and keeping the testing tip clean are essential practices. For instance, if you're using the tool frequently, wiping down the probe after each use helps maintain precise testing performance. This simple upkeep allows gemologists to rely on consistent results during their assessments, making it a worthwhile investment for professional use. -
Question:
How portable is the PGT II for on-site testing?
Answer: The PGT II is designed with portability in mind, making it convenient for on-site testing. Its compact size and lightweight construction allow gemologists to carry it easily during outdoor exhibitions, jewelry fairs, or client meetings. This portability means you can provide instant on-the-spot evaluations, enhancing customer confidence and satisfaction when buying or selling gemstones. -
Question:
What is the accuracy rate of the PGT II?
Answer: The accuracy rate of the Presidium Instruments Gem Tester II PGT II is exceptionally high, making it a reliable choice for both professionals and enthusiasts. It can successfully discern diamonds from moissanites with over 95% accuracy if used correctly. Having such a dependable tool means gemstone evaluators can confidently assess authenticity, leading to more trustworthy transactions in both retail and wholesale settings. -
Question:
Can the PGT II be used for identifying both rough and polished stones?
Answer: Yes, the PGT II is versatile in that it can test both rough and polished stones effectively. This adaptability is particularly beneficial for gemologists working with uncut materials as well as finished gemstones. In practical terms, whether you’re assessing raw gems from a miner or evaluating finished pieces in a jewelry store, the PGT II provides reliable results across both categories. -
Question:

Presidium Diamond Testers Editorial Review
The Presidium Instruments Gem Tester II PGT II receives a mixed yet generally favorable reception among customers who utilize it for gemstone identification. Users with extensive experience in the field, such as gemologists and geologists, appreciate the tester's portability and ease of use, stating that it provides a reliable method for distinguishing between glass and genuine gemstones based on thermal conductivity. With proper calibration—which many reviewers emphasize is crucial to accurate readings—the device reportedly performs excellently, yielding results that align with initial expectations. Calibrating the tester presents a learning curve for some, but those who invest time in understanding its mechanics often find it rewarding. A few users initially struggled with calibration due to user error, highlighting the importance of technique, such as gentle contact rather than pressing down hard with the probe. Once users become familiar with the device, they often report satisfaction with its ability to accurately test a wide variety of gemstones, although they note that it can only provide a preliminary indication rather than a definitive identification. However, some negative feedback arises concerning durability and customer service. A few reviewers expressed frustration when their devices malfunctioned or stopped working entirely after a short period. Customer support experiences were also inConsistent, with some users reporting a lack of response from the company when seeking assistance for issues. Ultimately, the Presidium Gem Tester II is regarded as a valuable tool for gem collectors and resellers, especially when approached as an entry-level tool rather than a replacement for comprehensive gemological analysis. It effectively identifies glass versus genuine stones but does not independently distinguish between lab-created and natural gems, which could disappoint some users looking for more sophisticated results. **
