Fluorescence isn't that big of a deal. The only time I've ever noticed mine is under a blacklight in a night club...and that's a rare occurrence these days..lol. Some people say they can show the fluorescence in sunlight (like take on a blue color) but mine does not. I guess if there is a stone you are interested in, ask them to take it in the sun and report back.
I LOVE fluorescence in diamonds.
