DiamondNite is the first and only one step dual tester for non-diamond such as cubic zirconia, artificial moissanite, or genuine diamond.

Just touch the probe to the stone - lights will show, if its moissanite, other artificial diamond, or a genuine diamond; confirm it by beeps - 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!
