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 and thermal 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 luminescent mounting extends about the contact to provide, in response to the control signal, a color indication of the identified gem type.
Claims16
A gem tester for testing a gem under test, the gem tester comprising:
- an elongated body;
- a probe extending from the elongated body;
- a circuit portion located within the elongated body, the circuit portion being electrically coupled to the probe to measure electrical conductivity of the gem under test;
- the circuit portion configured to determine identified type and drive a color control signal in response thereto;
- a luminescent mounting extending from the elongated body proximate the probe and disposed communicatively with the circuit portion, the luminescent mounting providing a plurality of colors corresponding to the plurality of gem types, the luminescent mounting lighting one of the plurality of colors in response to receiving the color control signal;
- and
- a line-of-sight contour extending along the elongated body, including the luminescent mounting to the probe.
