Abstract: An item of jewelry has a decorative element that is provided with a shaft which interfaces with an annular element such as a ring. A portion of the ring has, within its thickness in the radial direction, a radial notch, followed by a circumferential notch, thus forming approximately a L-shaped notch. An elastically deformable element is accommodated on the inner face of the ring, making it possible to lock the decorative element in position on the annular segment after introducing the shaft as far as the bottom of the L-shaped notch.
