Greeting all and warm wishes for spectacular 2008.
I am working towards taking my 20 stones exam at GIA and am looking
at many stones. GIA stopped selling their fiber optic light so never
though of buying one. Now, I am feeling that a more intense light
source will be very helpful and would welcome advice on fiber optic
lights. Which one to buy? Is 250 watt desirable (or 150 watt)? Is
there one that has a sodium light attachment? Anyone want to offer
advise on how to prepare for the 20 stone exam?
