Separate diamonds from most simulants with this presidium diamond mate tester.

This Presidium diamond tester uses thermal conductivity to instantly distinguish diamond from most simulants. Touch metal and an intermittent beep will signal to alert you. LED display and continuous beep indicate diamond or moissanite reading. A separate instrument must be used to distinguish moissanite from diamond, we recommend the Presidium Moissanite Tester II (DC333M2). Operates on 3 AAA batteries (not included), or optional AC adapter (sold separately, DC333A3). A rechargeable battery version (DC333C) is also available.
