    摘要： A grading lamp for gemstones is disclosed. In one embodiment, the grading lamp includes a base having an open top with a bottom wall bounded by upstanding front, rear, and side walls, and a lid hinged to the rear wall for swinging between open, intermediate, and closed positions relative to the base. The lid includes an interior lamp recess having natural and ultraviolet lights behind a light diffusing filter. A tray within the open top of the base holds color reference stones and a gem under examination. In the intermediate position, the grading lamp mitigates outside ambient light and provides direct light from either the natural or ultraviolet lights.

    摘要： 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.
