Abstract

A precious stone testing apparatus includes a testing circuit housed in a housing and tester probe unit extended from one end of the housing. The testing circuit includes a UVA/UVC LED module adapted to emit UVA LED light and UVC LED light onto a stone being tested and a heating system adapted to apply heat to the stone being tested. When the stone being tested is placed close to a testing end of a quartz light guide column, reflections of the UVA and UVC LED lights to the stone being tested are guided back to a UVA/UVC optical sensor while a thermal conductive tube encircling the quartz light guide column applies heat generated from the heating system to the surrounding of the stone being tested at the same time.
