Abstract
An annular piece of jewelry such as a ring or a bracelet has an outer crown able to rotate between two annular lateral edges of an inner crown concentric with the outer crown. The inner crown includes the soldered assembly of two half-crowns having the same inside diameter, the same outer configuration, and substantially the same axial length, each of the half-crowns being formed of an annular element which has, at one end edge, a convex bearing able to form a lateral retaining bead for the outer crown and a cylindrical annular bearing, able to engage the outer crown, each of the annular elements having, at its opposite end edge, a tubular bearing with a thickness smaller than the thickness of the cylindrical annular bearing, the smaller-thickness tubular bearing extending from the inner surface and the outer surface respectively of the annular cylindrical bearings in such a way as to define an internal annular cavity able to receive a soldering material when the two annular elements are brought into abutment to form the inner crown.
