I always thought the perfect e-ring would include the "perfect" diamond, but lately I''ve been leaning towards saphires. I''ve tried looking at some local B&M stores (to get some ideas), but the saphires don''t look very clear or sparkly (they''re quite dull, actually), and the selection is extremely limited. I would love a rectangular cut with a fine pave bezel and a dainty pave band/shank. Any suggestions as to where I might find something like this - either on-line or at an actual store (I''m in San Francisco). Thanks!
