Abstract
A gem tester for testing a gem under test and a kit including a horizontal recharging stand are disclosed. In one embodiment of the gem tester, an elongated body has a line-of-sight contour tapering from a bulbous end to a radially deviating frontal nose having a probe extending therefrom. Internal circuitry measures electrical conductivity of the gem under test in order to identify the type of gem under test and drive a color control signal in response thereto. A light source is disposed proximate the probe in order to expose the gem under test to ultraviolet light prior to the internal circuitry measuring electrical conductivity. Identification of the gem under test may be made by audio or visual indication or a combination thereof.
