We are pleased to announce some new styles of gemstones wraps! This one features two 4 mm princess cut, genuine blue topazes set in solid 10k white gold. The gap between the two topazes is 5.5 mm (slightly more than 3/16 inch). That means the mounting of your solitaire, not the diamond itself) must be smaller than 5.5 to fit in the wrap without having your jeweler adjust the bridge. Please measure. Do not assume all solitaires will fit. The wrap comes in other gemstones and gold colors. Please email us for availability if you want a different stone. The wrap weighs 1.9 grams and is a size 6.5, sizable by your local jeweler.
