Presidium Diamond Testers Editorial Review
The Presidium Diamondmate-c Electronic Diamond Tester has garnered a largely positive reception among customers in the jewelry industry. Reviewers have highlighted its simplicity and accuracy, praising its effectiveness in detecting real diamonds. Many users appreciate the fair pricing relative to its performance, particularly noting its reliability when assessing jewelry that is a few years old, which is likely to contain natural diamonds. Several reviewers mentioned that while the tester does not differentiate between natural and lab-created diamonds and does not measure color and clarity, it performs well within its primary function of verifying whether a stone is indeed a diamond. Users found the device to be user-friendly, with basic operational guidance making it accessible for beginners. However, a noteworthy tip was offered for testing smaller diamonds: users should avoid making contact with any metal and should test straight down to get accurate results. Conversely, there were some criticisms about the device. A few customers encountered issues with the device's functionality, mentioning faulty tips and lack of replacement parts or customer support regarding those issues. Additionally, the absence of clear charging indicators was noted as a drawback, leaving some users uncertain about when the device is fully charged. Overall, the Presidium Diamondmate-c has established itself as a trusted tool amongst jewelers and jewelry enthusiasts, especially valued for its price-performance ratio and ease of use. However, potential purchasers should be aware of possible concerns regarding replacement parts and instructions. **
