The Diamondnite tests for non-diamond, moissanite and diamond accurately and quickly.
The DiamondNite tests for non-diamond, moissanite and genuine diamond with one touch in only 1.5 seconds! No beep means it is a simulant other than moissanite. Initial warm-up time is eight seconds and recovery time between tests is just one second. Completely portable, the DiamondNite uses one 9-Volt battery (included), and has a 3 minute shut-off alert that saves battery life. The unit comes with a 2 year manufacturers warranty.
