Prestige Series II Diamond Tester

The Prestige Series II Diamond Tester is one step above the Diamond Detective, by virtue of its Manual Range Adjuster and 12 LED display which gives more information, essentially a gradation of Thermal Conductivity, instead of just a Yes or No answer.  Thus, conductive "colored stones" such as Ruby and Sapphire will be identifiable as well, by a high reading in LED lights displayed, yet short of Diamond.

Features:

• Test mounted or unmounted stones.
• Automatic and manual mode with advanced testing features.
• Identify CZ diamonds and other stones such as sapphires.
• Linear display for increased information.
• Adjustable gain for small stone sizes.
• Compensation for ambient temperature.
• Fast warm up time just ten seconds!
• Auto shut-off with a push button switch.
• Unique new anti-fade circuit which compensates for stone heating.
• 9V Battery included
• Low battery indicator for accurate readings.
• Complete instructions included
• Two year warranty.
