how to be certain a design line is not a crack
Hi Everyone,
If there is already a thread about this, I couldn't find it, so I am creating a new one with my question.
When I have a bead with a lot of movement or design, how can I determine for sure that a line I see is not a crack? I have done the obvious, shone a bright light through it, used my magnifier glasses AND and a magnifying glass (separately and together), tried to look from the hole up through the bead, taken it out in the sunlight...
Is there a tried and true method for crack-checking (that sounds weird...) I can do at home that will assure me the bead is whole and sell-able?
Thank you all for your combined wisdom. 
~Beth

Cracks sparkle a little when you move the bead around in the light.

Thanks everyone for your responses. I have found many cracks because of photographs, or just through the viewfinder. But this one bead I have now has me stumped. I'm 95% sure it's just the way the surface layer moved over a lower layer, but not confident enough to put it up for sale. It's really pretty, and the focal of a set.
Thanks for the info about the polariscope. I didn't know what that was. My local lampwork group has a tool library and I think there may be one I can borrow. I'll check it out. Thanks again everyone for your answers.
