This is a sterling silver bracelet with a statement circular clasp (you press the cut section to open and close). The chain has a pattern - one long link followed by three short. It's a simple pattern that catches the eye without being too flashy.
The clasp is 18mm across (diameter). The chain is 3.5mm at widest point. The chain is 26.5 cm long, including clasp, and 26cm when fastened. It's a little smaller than average for a smaller wrist.
