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. **
