Hi all, we have just made a sapphire halo engagement ring with a very reputable hand made jeweller. On picking it up we were over the moon, he got the brief perfectly. i soon noticed a dark area in the centre of the stone. It's very noticible to me in most lights, it wasn't noticible under the shop lights or even in my kitchen. But in every other room in my house and most natural light settings it's all i can see. A quick Google led me to believe it was extinction and windowing. When i then held it up i could see the window. The window itself doesn't bother me so much, it's the dark area. We contacted the jeweller to ask about finding another stone as it is the only thing stopping me from loving it. He seemed to think this was an amazing stone and that if i found fault with that one he didn't think he could get another that i would like. He's happy to refund the whole thing if I'm not happy. I don't think it's unreasonable to try to find a stone without these issues , but obviously we are new to this and we do trust this jeweller. I've attached some photos of what it looks like when it's noticible, so not the most flattering. In the right lights its actually a stunning stone. I just find that it detracts from the rest of the stone and we've spent a lot of money for it to not be right. Any suggestions or feedback welcome.
