I'd love to see real life pictures of it as a comparison to the Grace eternity I am considering. The appeal is that they are larger stones than the matching eternity ... But I'm not sure!
This was a custom piece I had Brian Gavin make for me several years ago and he now carries it as part of his line. It was a beautiful Piece, you would need to make some sort of adjustment on your ring size though as the "swoopy U" shape gives a little more room. So If you are normally a size 4.5, I would size down 1/4, otherwise it may feel looser. I ended up repurposing the diamonds as the girdle of the diamond hung over a little more than I would like it to, so if you were planning to wear this next to an E-Ring, I recommend some sort of plain spacer as the girdle of the diamonds did hang quite a bit over the metal but this ring was super low profile which I absolutely loved. This has a more metal between the diamonds than the shared prong you are considering.
Thanks D&T - this is really helpful and it makes me wonder whether it would rub any less than a shared prong band ... But I did ask Denise at BGD and she said due to the super low profile it could work ... I have gone back with more questions to try to confirm whether the donut on my e ring would provide enough protection.
