Description

The Pro-D3 white diamond and sapphire tester from GemOro® offers the protection against fraud. This tester uses electrical conductivity testing to reliability identify white diamonds and sapphires.
• Designed in the USA with exclusive, patented ergonomics, the Pro-D3 fits comfortably in your hand.
• Patented intuitive finger pads provide a user-friendly ease of use, a sure grip and added comfort.
• The probe tip is retractable for increased durability and protection against damage.
• The tester warms up and is ready to use in seconds with patented visual indicators, a glowing tip and light pipe. Visual results are color-coded for clarity: GREEN for diamond, PINK for white sapphire, and RED for metal alert (which warns you if the probe touches metal as you're testing stones).
• An impact-resistant, virtually indestructible ABS housing with protective rubberized coating helps ensure durability and long service life.
• Auto-off function help preserved battery life.
• The tester itself carries an unprecedented limited lifetime warranty. The probe tip includes a two-year warranty (Note: in the event that the tip is damaged, the entire tester is replaced).

The Pro-D3 includes:
• Three AAA rechargeable NiMH batteries (tester accepts standard alkaline batteries as well).
• Micro USB cable with universal dual voltage AC adapter/charger cube.
• Loose stone holder.

Please Note:

BE AWARE: This tester is not reliably effective on natural or treated colored diamonds. Because some colored diamonds (natural and treated) are electrically conductive, the GemOro Pro-D3 ideally should be used on colorless stones only. This limitation applies to all testers that use thermal and electrical conductivity methods for testing the authenticity of gemstones.
IMPORTANT: This item is wired for dual 110- and 220-volt capability and is sold with a U.S. plug. Because amperage, outlets and plugs vary widely by location, you may need a different plug. If so, you are responsible for having the appropriate plug or adapter installed by a qualified professional. Rio Grande assumes no liability for improper or inadequate re-wiring or adapters procured by customer.
• WARNING! Do not place the GemOro® Pro-D3 into an GemOro Ultradock 3 for charging if the tester is loaded with non-rechargeable batteries (such as alkaline-type batteries). Using the Ultradock 3 charging station with non-rechargeable batteries can result in dangerous pressure develop within the battery cartridge, potentially causing a leak or an explosion of corrosive material, causing severe damage and/or injury.
