Thank you mrs-b! This is actually a stock setting on their website but it features an RB. They do show a photo of a ruby marquise stone in the setting with these prongs which is what I specified I wanted for my ring. There was no extra charge. I met with the owner twice in the past (but not for this ring) so I had a lot of confidence that things would be done right although I know there’s been some changes in ownership of the company but I couldn’t be more pleased with the outcome.
