Presidium Gold Testers Editorial Review

Presidium Instruments Gem Indicator PGI Handheld Tester is a compact and portable device that can be used to identify diamonds as well as common colored gemstones such as emeralds and rubies. It comes with a calibration disk, USB cable, user handbook, and protective carrying case. According to the FAQ section, the device is not accurate in displaying rubies and emeralds, and it cannot determine moissanites from diamonds. However, it can identify rough gemstones based on their characteristics such as hardness and density. There are mixed reviews as some customers claim that the device gave inConsistent readings, was defective, or did not identify any gems accurately. Still, other customers found that the machine was easy to use and worked well in identifying gemstones.
