DiamondNite is a one step dual tester for non-Diamond such as Cubic Zirconia, artificial Moissanite, or genuine Diamond. Just touch the probe to the stone - no beep means it is a CZ or other fake, the first continuous beep means Diamond (green light), or if it is followed by a lower continuous beep, then it's Moissanite (red light). The initial warm-up time is five seconds, the test itself takes only 1.5 seconds, and recovery time between tests is an astonishing one second!
