Cubic Zirconia Real Or Fake Does Moissanite Look How To Check Diamond Quality Sapphire Ruby Tester Identify Raw Diamonds

GLIS-3000 GEM Luminescence Imaging System can help the user to judge batches of small diamonds quickly (as small as 0.001 carat) and mounted diamond. The Ultraviolet fluorescence image and the phosphorescence image of natural diamond and synthetic diamond are different. GLIS-3000 excites diamond to becomes luminescence through the built in Ultraviolet light source, captures and records the fluorescence and phosphorescence image of the sample, and we can find out the position of the suspected diamonds with problem by analyzing the relevant images.

(1)The fluorescence and phosphorescence of diamond:

When exposed to UV light, diamond can emit different intensity of the blue visible light, which is fluorescence. If we remove the UV light source, diamond can still emit visible light, this is phosphorescence.

(2)Measurement area up to 10cm*7cm

(3)The simultaneous measurement of fluorescence and phosphorescence

(4)The simultaneous measurement of batch diamond, the ability of measuring the bare stone and inlaid diamond

(5)The ability of measuring diamond with any shape and size, the smallest size of measurement is 0.001 carat.
