jewelry ultraviolet fluorescent lamp

Ultraviolet Lamp with dual wavelenth:365nm long wave and 254nm short wave ultraviolet light

Preset a viewport with magnification eyepiece, so that the user can see a magnified sample. (Proprietary technology)Drawer type observe darkroom: better observe effect in dark room and easier to take Gem. (Proprietary technology)voltage: can be choosed 110V or 220V, watage is 4WSpecial diamond grading device, table  and pavilion  two kinds of  observation way,and  the tested diamond is moved in drawer type observe darkroom.

Non-fluorescent soft baseboard, benefit for observing effect and protecting the gem not be scratched.

Functions:

1.Identified the species of the gemstone:some gemstones possess strong fluorescence,such as Ruby with red fluorescence.

2.Help distinguish the natural gem from synthetic gem: most natural sapphire without fluorescence

3.Help to distinguish the natural gem from manaul processing gem:such as the jade,jade with fluorescence  and completely shine. some jade that acid treated  filled with rubber, the rubber has fluorescence.

4.Help to identified the diamond and the fake:the color and  intensity of diamond fluorescence changes greatly,presents different color:blue ,green,yellow,pink; strongth presents strong,middle,weak.non.this phenomenon significant to the cluster seeting diamond,whilt the fake present the uniform fluorescence.Diamond fluorescence help to distinguish the natural diamond and synthetic diamond.

Attentions:

Fluorescent light is harmful to eyes,when testing the gem,do remember don't look at the light directly.
