Silver ball chain bracelet with a spring ring clasp, easy to use and perfect for casual styles. - Material: Silver 925 (925 stamp, photos 3 and 4) - Design: Ball chain - Clasp type: Spring ring - Style: Casual - Size: 20 cm (My wrist measured 17 cm with a string. The feel when worn is shown in photos 5, 6, and 7.) Weight: 10 grams Ball width: 4.5 mm Spring ring width: 11 mm Simple yet with a 4.5 mm ball chain, it has a moderate weight. There is no stamp on the chain itself, but it uses Italian-made chain, and the spring ring and catch are made in Japan. The ball size is about the same thickness as ball chain bracelets often seen at GUCCI and Tiffany. Thank you for looking.
