I'm new to the forum, but just getting back into collecting and doing some custom pieces after a 5 year hiatus. I've got a soft spot for blues and particularly blue sapphires. Beyond the precision cutters in the vendor list, do PSers have any preferred vendors for high quality sapphires say 2 - 5 carats? Working on a piece with this 1.93ct glowy cushion cut beauty I'd purchased from Gemfix years ago.
