DiamondNite Dual Tester Jewelry tool

DiamondNite Dual Tester
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.
