The box has a top portion hinged with a bottom portion. A compact ultra- violet LED assembly is mounted at a mounting angle in the insert in a cavity of the top portion. The LED assembly has: an LED circuit; a 3 watt 365 nm ultraviolet LED diode dis - posed on the LED circuit; and an optical collimator having a parabolic lens to focus the emitted LED radiation to a less than 15° spread. A compact battery for powering the LED as - 100A sembly is provided in a recess of the bottom portion. A cent- ral holder/deck holds the gemstone in a direct path of the emitted collimated LED radiation of the LED assembly. In operation, the gemstone seated in the central holder/deck l emits a corona of strong visible fluorescence while the ultra- violet radiation and the LED assembly are not seen. 110A O WO 2017/120441 Al 111111110111101110111111IIII1III011101111111111111M01111011111111111110111111 Published: — with international search report (Art. 21(3)) — with amended claims (Art. 19(1))
