Mi Belleza Jewelry's Rome's Embrace of Love Anniversary Bracelets for boyfriend and girlfriend are very romantic but not cheesy, as only the two of you know that these roman numerals represent your anniversary. Both of the matching bracelets are made of real sterling silver and can be adjusted to size. The black bracelet in this set is a silver bracelet dipped in oxide, that gives it its edgy, black color. Both of the bracelets have a beautiful, delicate frame with roman numeral letters in between. You can choose any combination of letters and numbers and personalize this bracelet set to your needs.
