Have I cracked my sapphire?
I bought my first loose sapphire from what I hope was a trustworthy source here in Scotland. It came in the post, I was so excited, and then I dropped it immediately upon opening it, like an idiot.
There's a very crack-like structure internal to the stone: it flashes very brightly and is visible to the eye when you look from the side. However I don't see ANY surface cracks with my loupe, though there is a super tiny chip on a different facet. I asked the seller and he said there was definitely a small inclusion on one side. I got the stone for only £250 and so I didn't by any means expect it to be flawless, so if it is an inclusion I don't mind one bit.
bUT if it is a crack, then every time I look at the stone I will be reminded that I am a bit of a tit.
I know it's next to impossible to determine anything from photos, so they here for support not diagnostics;
If it doesn't make it to the outside of the gem surface, could it still be a crack/structural problem? The sources I found said no, it is more likely to be an inclusion, but I was hoping for some advice
If I have just been hoodwinked: could glass stones crack like that, without coming to the surface? It's a parti-sapphire (the light in the photos make it look just awful and swampy but it has some great colour splitting), so if it's a fake it's a good enough fake that I am still happy to wear it around but I won't embarrass myself by talking about my sapphire!
All of the advice is going to be 'take it to a jewellers', I can tell. Would a jeweller be happy to just say 'yes/no, sapphire, yes/no crack' without me having to get it fully appraised/certified? I am happy to pay just to know if it's something they do for £20-30 but I don't think it's worth £150-200 (for this stone, not the service).
Thanks for your help!
