My fiancé and I are shopping for a round center stone for a three stone ring; our budget is 4K for the stone. The side stones will be my great-grandparents' hand cut round diamonds; both are half a carat, and I think at least H. We want an eye clean diamond, probably H-ish or better to match the sidestones, as large as practical for 4K (maybe just under a 1?). I would consider an older cut but don't think it's necessary. We are interested in buying online due to busy schedules. Any suggestions? Thanks.
PS--My finger size is 4.5.
