I have basically it's twin from Bob, would not be surprised if they were from the same parcel. They are so similar I had considered getting that one as a match but really had no plans for what I'd do with them. It is nice to own an unheated ruby but honestly the color is so muddy and dark to me I doubt I'll ever set it because it would look so dark. Can't argue with his prices though.
I just think that stone has such nice character. Personally, I like that size for pendants. Most of my stones are 4-5mm in pendants as I like to sleep in them and wear them for a week or two before switching to another. Should fit perfectly in a calibrated 5mm princess setting which means you could probably pick a setting and chain out of a stuller or other catalog for under $200.
