Best Review
Customers find the diamond tester works well, particularly for stones 1 carat and above, and appreciate its value as a fairly inexpensive way to test diamonds. The device is simple to use with well-written instructions, and customers confirm it can detect both real and false diamonds. While some customers find it highly accurate, others report inconsistent readings, and the build quality receives criticism for being flimsy and made of cheap plastic. Additionally, the battery capacity is problematic as it requires a 9V battery that doesn't last long, and customers mention the device beeps constantly.AI Generated from the text of customer reviews
