Editor’s Note
The SmartPro MAX, a new all-in-one gemstone tester from Ernst & Friends, promises rapid identification of diamonds and simulants using a unique combination of thermal and optical testing in a single device.

The new SmartPro MAX – exclusively available at ERNST & FRIENDS – can identify natural diamonds, synthetic diamonds (CVD/HPHT), moissanite, simulants, and even cubic zirconia within seconds. This capability is enabled by SmartPro’s patented technology, which for the first time combines thermal (thermal conductivity) and optical (UV transparency) tests using a single probe. With these and many other features, the MAX is unique in the market of portable diamond testers and sets new standards.
He notes that it can happen, for example, that synthetic diamonds are occasionally found among batches of loose diamonds.
The device’s operation is very intuitive and simple, allowing it to be learned in just a few minutes. The tests work on both loose and set stones.
With the SMARTPRO brand, the company ERNST & FRIENDS from Northern Germany offers professional and extremely user-friendly testing devices for distinguishing between natural and artificially produced diamonds – at affordable prices. The innovative SmartPro devices can be controlled via the intelligent SmartPro App, including convenient certificate creation for handing over to customers and for one’s own documentation.
