thank you both very much!
He''s been delightful over email. It''s great to hear that a PSer had a very good experience too. Thanks Chrono!
He doesn''t have quite what I''m looking for right now but is keeping an eye out for me. Well, he has a tanzanite that is exactly the size and shape that I want, great price, and I like the color too, but I think it may be wiser to stick with a sapphire for its durability. (This is for a bezel set RHR). I do really like the tanzanite - will have to keep thinking about it!
