I decided to go with R3833, set in the rose gold underwire...I just got off the phone with David

Mrs. Mitchell, THANK YOU for the pictures here - they totally confirmed my choice to go with rose gold. I have no idea what this little round will look like set in that color gold, but I am excited to learn!
Yay! I'm so glad you went with this combination, it's going to be incredible! Happy to help.
The rose gold and the comparatively open setting worked wonders for my oval. It was previously set in a bezel pendant and it just wasn't letting that stone shine. It's incredible in the underwire, and although it's a white diamond, it's a warm white with strong blue fluorescence and the rose gold is very flattering to its colour. Great choice for your stone, I think!
