Ensure the authenticity of your precious stones with the Professional High Accuracy Diamond Tester Pen. This essential tool for jewelry enthusiasts and professionals is designed to distinguish genuine diamonds from common stimulants like cubic zirconia and glass. Utilizing advanced thermal conductivity technology, this portable device provides instant, reliable results through a clear audio and visual feedback system, making it an indispensable asset for buying, selling, or verifying your jewelry collection.
Key Features
Precision Thermal Conductivity Sensor: Equipped with a highly sensitive copper probe that measures the heat dissipation of gemstones to accurately identify real diamonds.
Dual Indicator Feedback System: Features a 10-level LED light scale and a distinct "beep" sound to indicate the hardness and authenticity of the stone.
Metal Alert Protection: Built with an intelligent sensor that emits a continuous buzzing sound if the probe accidentally touches the metal setting, preventing false readings.
Adjustable Calibration Control: Includes a sensitivity dial to calibrate the device based on the size of the stone and the surrounding room temperature for maximum accuracy.
Ergonomic and Portable Design: The sleek, pen-shaped body fits comfortably in your hand and comes with a protective leather pouch for safe transport to auctions or estate sales.
Complete Professional Kit: Includes a dedicated loose stone testing tray, ensuring even unmounted diamonds remain stable and secure during the testing process.
Why Choose This Diamond Selector
Relying on a visual inspection alone can lead to costly mistakes, as modern synthetics can easily fool the naked eye. This professional selector offers a laboratory grade solution by testing the physical properties of the material. It is engineered for simplicity, requiring no professional training to operate; if the stone is a diamond, the level indicator will climb into the red zone and beep. It is a cost effective and reliable way to gain immediate peace of mind regarding the value of your jewelry investments.
