Abstract: An article of jewelry includes an annular support element including a circumferentially extending continuous groove on its inner periphery, and a disc-shaped sandwich mounted on the annular support element by being partially received in its groove. The sandwich includes a transparent protective element; a precious metal substrate carrying an image, especially a laser-engraved relief, on its major surface that faces the transparent protective element; and a bonding agent between the substrate and the element for improving the clarity of the image visible through the element. The annular support element is constructed as a split ring having a gap, and there is provided a mechanism for controlling the size of such gap to tighten the support element around the sandwich.

Abstract: An article of jewelry includes an annular support element including a circumferentially extending continuous groove on its inner periphery, and a disc-shaped sandwich mounted on the annular support element by being partially received in its groove. The sandwich includes a pair of confining elements at least one of which is transparent, and at least one precious metal foil confined between the confining elements and carrying at least one image, especially a laser-engraved relief, on its major surface that faces the transparent one of the confining elements. The annular support element is constructed as a split ring having a gap, and there is provided a mechanism for controlling the size of such gap to tighten the support element around the sandwich.
