This is a charming 9K gold curb link chain bracelet from the Edwardian era. It has a secure heart padlock with the markings “JC&S” (the maker's mark of Joseph Cook and Son Ltd, from Birmingham) and the marking "9K". The padlock is great because it operates as a clasp but then also wears like an additional charm.
Each of the curb links measure about 8.6 mm by 10.3 mm and have all been marked “9K”. The entire bracelet weighs 15.5 grams, and it measures about 9 inches from end to end.
A great piece great for everyday wear!
