    I don’t have my ring yet, but it’s being made from a piece of my fiance’s grandmother’s jewelry. I just picked the setting today (she sent suggestions from Florida where she lives, to my fiance in New York, who mailed them to me in Texas). The stone is marquis cut and I like a semi-sideways setting for it.
