I wouldn't expose it to sunlight if I could avoid it. The color (mineral staining) can last years if cared for.
I have some that's quite old that still has vibrant color. If you're truley worried, you can use a finish with UV inhibitors but they tend to have less clarity due to the pigments in the finish.
How much the color will fade is anyone's guess, evey situation is different.
