Hi I went to a Tiffany''s in Tokyo, and since I''ve leared so much from PS, I specifically asked for more information about the diamond other than just the cut and color. I ask about the pavillion, table, crown etc. But the salesperson told me that they don''t really show this kind of information until you purchase the ring. When I insisted, she showed me a copy of the certificate, but didn''t let me keep it. I find if very hard to get them to show me the details. Is this typical? or just in Japan because consumers here don''t really ask for it? thanks
