A continuous line of round brilliant diamonds, each roughly 0.05 carat, set in individual four-prong links joined edge to edge so the bracelet articulates and drapes rather than holding a fixed shape. 17cm long and 2.5mm wide, with a concealed box clasp and a safety catch. The articulation is what separates a good tennis bracelet from a stiff one, and it is entirely a question of how the links are built.
