Is this air bubble ok?

[Amber]

This bead has a pointy air bubble right on the core...I just wanted to know whether it is could cause problems (cracking etc)? I made it several months ago and it seems ok so far - but I obviously don't want to sell it if it's likely to fall to pieces or something!

Any idea?

Looks like the answer is that no-one knows!

I'd say that if it been Annealed properly then you've relieved all the potential stress within, that area and not to worry about it,  I use Air bubbles quite a lot in dot implosions and ive not had one crack , even when they've not been annealed until sometime after.
