Blue diamond in antique setting...

[sparkler-crazed]

need some help - friend is looking for a blue diamond engagement ring (enhanced-budget is limited), preferably in an antiques setting - does anyone know of a trusted store to buy from?
I know NOTHING about these stones but want to help him out.
THANKS!!
