The Mizar "Diamond Detective" state-of-the-art Tester is simple but precise, giving the user a quick "true/false" reading. Housed in a high-impact plastic case, it is everything you will need to test diamonds in rapid succession, whether the stones are mounted or unmounted.

Operation of this unit is simple. Turn the unit on, wait five to seven seconds for the "Ready" light, select whether it's a large or small stone, and touch the probe tip to the stone. A light will turn on along with an audio indication if the stone is a diamond. No external power cords or clips necessary, this diamond tester uses a 9-Volt battery.

Features include:

• Metal alert (a long beep when user accidentally touches metal rather than stone).
• Large/small switch for testing diamonds over and under 8 points.
• Diamond indicator (a green light), which illuminates if the stone is a Diamond.
• 7 second warm-up time with a 150 second shut off alarm.
• If the stone is a simulant such as Cubic Zirconium (CZ), nothing happens (except with Synthetic Moissanite).
• Comes with complete instructions and carries a 2 Year Manufacturer's Warranty that excludes  battery and tip damage.
• Low battery indicator, 9-Volt battery included.
• 2 year manufacturer's warranty included.
