[QUOTE="mbasko, post: 671059, member: 4485"] Even though most gemstones fluoresce better in the UV shortwave range others, like ruby, are better in the UV longwave range, which is why serious punters have both ranges no doubt. Interesting that from 280 to 315 isn't used. There are a lot that seem to be promoted at 365nM. Possibly due to still able to get a reaction & in the safer range? The UV shortwave range is pretty hazardous & requires protective glasses etc. if anyone is thinking about using them. [/QUOTE]
