We at Metal Detectors South Africa (MDSA) often receive inquiries from gold prospectors across Zimbabwe, Zambia, Mozambique, Congo DRC, and Southern Africa. One of the frequently asked questions is: “Can a metal detector detect diamonds?“
In short, no, a metal detector cannot detect diamonds. The reason lies in the nature of both diamonds and metal detectors themselves. Let’s delve into the technical details of why this is the case.
The Science Behind the Detector
Metal detectors are designed to locate metallic objects, including gold. They work by transmitting an electromagnetic field into the ground. If a metal object is in the vicinity, it will generate an electrical conductivity response, which the detector picks up, alerting the user.
Diamonds, however, are non-metallic and non-conductive, meaning they do not react to the electromagnetic field emitted by the detector. As a result, diamonds remain undetectable by standard metal or gold detectors.
The False Promises of Fake Diamond Detectors
Regrettably, there are operations out there selling fake “diamond detectors.” These devices often claim to be able to locate diamonds hundreds of meters underground and tend to be on the expensive side. However, it’s important to understand that these so-called diamond detectors are, unfortunately, not genuine. We’ve heard countless stories from prospectors who, in good faith, have purchased these items, only to find they do not deliver on their promises.
Meet the BIG JOHN DETECTORISTS DIAMOND TESTER
While metal or gold detectors cannot identify diamonds, we at MDSA do provide a diamond test: the BIG John Detectorists Diamond Tester.
