This sterling silver rolo shaped link charm bracelet with large heart toggle clasp! I also have a similar bracelet in other size links, lengths and hearts. On the 7" bracelet each round link is 8 mm in diameter. The heart is 30 mm tall and 25 mm wide. It is nice!!! The 7.5" version is a little different. The round links are also about 8 mm in diameter, but the heart is 28 mm tall and 22 mm wide including the fixed round connector. This one weighs about 18 grams. The toggle bar is heavy and about 27 mm long.
