Diamond Tester DiamondNite Dual Tester

Buy here: www.esslinger.c...
The DiamondNite tests for diamond and cubic zirconium or synthetic moissanite, so it is a true dual tester. We promise you'll be amazed by the accuracy and simplicity of this tester. One touch to the stone - no beep means it is a cz or other fake, first continuous beep means diamond (green light), if it is followed by a higher continuous beep, then it's a moissanite (red light). Guaranteed by the manufacturer for two years - unconditionally.
• DiamondNite is completely portable, uses on 9-volt battery (included)- no awkward cord or adapter needed.
• Three minute shut off alert to save battery.
• Simple on-off switch, no tricky adjustment.
• Gray shock resistant housing with easy-read features.
• Comes with complete instructions.
• Patent pending

Also have an earlier one from the 1990's that used a roach clip which you needed to clip on a piece of jewelry to test the stone. It still works and use it occasionally.
