Hello! My grandmother, who died 20 years ago, had this very pretty ring that she said was a sapphire. I'm not sure if any of you can say anything about it, but I'm wondering whether it's worth appraising. Sorry for my photo taking skills (awful) and I should have cleaned the stone... I can see my fingerprint on it. I took the pics with my iphone, natural light outdoors and against a dark background indoors with poor lighting. Thank you!
