<p>The ring (1) comprises a sleeve-like or annular substrate (2) made of a precious metal or of a precious-metal alloy with a relative density. The sleeve-like or annular substrate (2) has an inner surface (3), which is intended to come into contact with the finger, an outer surface (4), two side surfaces (5, 6) and a central cavity (7), for accommodating the finger. A bundle (8) of fibres (9) is wound up in a number of coils at least over part of the outer surface (4), wherein the fibres (8) are connected to one another by means of a transparent plastic adhesive with relative density ?2 < ?i, and the fibres (8) have a relative density ?3 < ?1.</p> |
