Re: GB 405nm Goggle $35 (Laser-Wave)
now here you see it nice and clear!
i would have guessed it shines at 694nm perhaps? could be the cam which sees wrong colors..
again, i actually used this effect: i got a white stone with small red sandgrains in, as a present when i was perhaps 10. was told its ruby. now, some weeks ago, i could verify without a doubt that its not ruby, but garnet!
how about a laser and googles at the next fleamarked? "oh, you want 10$ for this garnet-ring?" *quick check with the laser* "oookay, here come 10$" *goes off, trying not to laugh, with a 500$ antique rubyring* ;-)
