I have inherited an approximately 1 carat round transitional cut diamond. SI1, color I/J, approximately 6.48 x 6.56 x 3.80 mm measurements. Its previous family owner had it set in a terribly cheap silver pendant necklace setting that now has a broken clasp. I do not feel safe wearing this heirloom as a necklace and would like to put it into a right hand ring that can be loved and enjoyed. My engagement ring and band are white gold, the main diamond is a 2 ct radiant cut with sapphire and diamond sidestones. I am thinking I would like to put it into a vintage style setting, but I am conflicted about what would be best. I believe this stone is from the early 1900s, perhaps someone else can chime in with what setting would be appropriate for a stone of this age?
