Abstract: In a process for the production of smooth surfaced parts, a paste material, which includes paste or granule pieces which are coated with added pigment and then pressed back together, is applied, in the form of an extrusion or a coating, to a substrate. The extrusion or coating is subjected to a first, incomplete hardening, after which it is no longer flows freely under its own weight. The surface layer, containing added pigment, is then removed from a surface to be used. This surface is subsequently smoothed, and the hardening of the coating to form a hard material is completed. The smoothing and the completion of the hardening can occur in the same processing step as a shaping for the formation of separable shaped parts. The substrate can be inseparable from the hardened coating. The surface layer, containing added pigment, can be removed by mechanical means, solvents or abrasion by a suspension in liquid or air, if appropriate in the presence of ultrasound.

Abstract: An article of jewelry or wrist watches with at least one gem stone or a watch, the gem stone (3) or parts of the watch are associated with a holding element (2) and are interchangeably joined thereto together with a support (1). Thus, as a function of the individual taste of the wearer, it is possible to fabricate jewelry parts or decorative watches with different shapes and colors.
