Utility electronic precious gemstone type and quality detector

A utility electronic precious gemstone type and quality detector employing ultraviolet laser induced fluorescence in a gemstone of a test assembly of

• a testing stand,
• a testing probe and
• a gem receptacle for holding a gemstone comprising
• on said testing stand,
• a probe well located on a flip lid connected to said testing stand by a pivot pin and a test button array of depressible buttons to input inquiries concerning said gemstone and an alpha-numeric readout for visually displaying a response to input inquiries based on fluorescence characteristics of said gemstone and in said testing stand,
• a ROM testing circuit board with a micro controller unit that indexes encoded heuristic data tabulation of gemstone identity and quality to digital spectral information in response to inquiry from said test button array as output to said alpha-numeric readout and a gem receptacle retainer for holding said gem receptacle on-center below said probe well and
• batteries for powering said test assembly where said batteries are accessible by a latching battery cover and a probe cable containing wires from within said testing stand that mates said batteries, said test button array, said ROM testing circuit board and said alpha-numeric readout to
• said testing probe which contains components of a cable connector that fans out the wires from within said probe cable into a probe circuit board which electrically connects to a UV laser diode assembly and a solid state photo detector array mounted on a photo detector array mounting board that has a laser beam collimator aperture and also holds the matrix of said solid state photo detectors and on the exterior of said testing probe is a probe test button which, on depressing, initiates a sequence of electronic signals on said probe circuit board;
• wherein
• inserting said gemstone into said gem receptacle and placing said gem receptacle into said receptacle retainer within said testing stand, then inserting said testing probe into said probe well and inputting an inquiry by depressing button(s) on said test button array and then depressing said probe test button to initiate a sequence of electronic signals from said probe circuit board that activates said solid state photo detector array to obtain an ambient light spectrum data and then initiates said UV laser diode assembly to emit a laser beam through a laser beam collimator which illuminates said gemstone which fluoresces a spectrum to said solid state photo detector array where each spectrally limited photo-detector luminescence output channel is digitally encoded on said photo detector array mounting board for transmitting its
• digital information to said ROM testing circuit board which processes and decodes the digital inputs to the tabulation of gemstones digital information to evaluate type and quality of said gemstone which is displayed on said alpha-numeric readout.
