Just posted my question on a 2 carat round just below. When I finally make a decision on which 2 carat round to purchase I want to put it in a 3 stone platinum setting. Should I use a 6 or 4 prong setting? What size round stones would look appropriate next to the 2 carat round stone, .25 ct less or more? The main stone would be raised. Thank you for your opinions.
