I am looking at matched pairs to go with a 2.02 Oval center stone. Is there a recommended shape that looks best? I have seen heartts as side stones and they look very nice. I have had pear shapes recommended as well. Also, what are the guidelines for selecting matched pairs? I found one pear that is a 1B final AGA cut grade and another that is a 2B AGA grade. DOes that matter? Length to width ratios are 1.61 and 1.62, but there is a differnece in crown height and table and depth. WHen you look at the stones will they appear different? thanks to all who offer insight!
