Even expert jewelers can mistake a well-crafted slab of paste for the genuine article. Or at least that’s the theory behind DiamondNite, a hand-held gadget that beeps when it’s placed against a diamond, yet remains silent when brought in contact with cubic zirconia or moissanite. DiamondNite’s manufacturer won’t reveal how the device works, but Microkhan suspects it’s just a very basic (and slightly overpriced) breed of spectrometer.
Microkhan also highly doubts that the DiamondNite can catch truly well-done ersatz gems, especially in this day and age of the synthetic diamond. If DeBeers and its zillions of high-tech gadgets can’t tell the difference, neither can the $199 DiamondNite.
