Piece of jewellery e.g. ring

摘要

The ring has at least one very pronounced concave mirror-type element (2). A core (4) is mainly enclosed in its hollow, without filling it completely. The depth of the element between top edge and base is approximately forty to fifty percent of the top edge diameter. The concave curvature opens into the plane of the element opening at an angle of approximately sixty to eighty degrees. The exterior of the core has a structure and colouring, forming a contrasting picture on the mirror surface. The core is fastened in the base of the element via a plug, clamp and/or snap connection, or is contained loosely in the hollow element, which has a transparent cover.
