7 Ways To Tell If A Diamond Is Real (Jewelers Hope You Never Learn #1)

A woman hands her ring across a counter. The man picks up a small pen-shaped device, touches the tip to the stone, and a green light comes on with a little beep. Real diamond. She exhales. The stone in that ring cost thirty dollars. The device wasn't broken. The battery was fine. It did exactly what it was built to do — and the answer it gave was green, and the answer was wrong. And here's the part that should make you sit up: the man holding it had no idea either. 💎 ONE PIECE OF EVIDENCE FIRST: the manufacturers say it themselves, in their own patent filings. As the technology advances, moissanite is being produced with lower and lower electrical conductivity — stones with resistance so high that telling them from a true insulator with a portable battery-powered device is difficult, and in their words, even the best available testers cannot do it reliably. One of the tests on this list is free, takes ten seconds, beats the thirty-dollar pen every time — and almost nobody does it, because it doesn't look like a test. -------------------------------------------------------------------------- This video is based on over 20 years of firsthand experience in the jewelry industry combined with extensive research into publicly available financial reports, SEC filings, brand earnings calls, material spot prices, and secondary market resale data from platforms including Chrono24, The RealReal, and major auction houses.
