I want to buy a sapphire for my old ering setting. Here is a link to it, I sold the princess cut diamond that was originally in it.

My diamond was 5.6x5.7mm. I was wondering if anyone had any idea how to measure the setting so I know what size stone I need. I am looking for a cushion possibly an asscher. I do have a few loose stones I tried to place in there to get an idea. 6mm seemed too small (both cushion and asscher) and 7mm was too big (asscher) Think 6.5 is the right size? I should say both my 6mm stones are Wink's, would the Avarra sapphire be deeper? My 7mm is a light ceylon asscher.

Then do I go Kashmir or Dark Ceylon?

Thanks
