You see lots and lots of diamond wraps and occasionally a few gemstone wraps. But you don't see many blue topaz or other semi-precious gemstone wraps and I don't know why not! This one is so pretty and may have sentimental meaning to the December bride or baby! There are two 5x3 mm, pear cut, horizontally set, natural blue topazes for a total of approximately .50 ctw. They are set in solid 10k white gold. The opening between the two topazes is 4.5 mm so it is perfect for a 1 ct diamond but will also look good with about a 3/4 ct. I wouldn't go much above 1 ct though without a very tall mounting. The ring wrap weighs 1.1 grams and is a size 6, easily sizable by your local jeweler. Be different! Get a beautiful, affordable blue topaz wrap to dress up your solitaire.
