A method of forming an article such as a jewellery ring or bangle comprising: providing a first substantially annular-sectioned element and a second substantially annular-sectioned element, an outer diameter of the first element being less than an inner diameter of the second element; forming a circumferential groove in one of the first and second elements by a process of rolling; positioning the first and second elements together with the second element positioned circumferentially around the first element; and expanding the first element such that the circumferential groove in the one element receives therein the other of the said elements. |
