Article 59. Use of Non-Metallic Parts in Jewelry and Other Items Made of Precious Metals and Precious Stones

Non-metallic parts (inserts, enamel, niello) may be used in jewelry and other items made of precious metals and precious stones, provided that they differ in appearance from precious metals. In this respect, non-metallic parts of products should not have a coating or color that imitates precious metals.

Filling the handles of knives, forks and similar products with non-metallic materials shall be allowed in the amounts necessary to secure them.

Jewelry and other items made of precious metals and precious stones, manufactured with using non-metal parts, must have a special imprint indicating the range of weight of the precious metal. These products shall be subject to assaying, analysis and hallmarking in disassembled and unfinished form, but with the full presence of all parts made of precious metals. In finished products, secondary and additional parts of the product must be soldered. Secondary and additional parts of products must be hallmarked with a state hallmark or a fineness hallmark of the established sample.

Jewelry manufacturers shall submit to the Assay Chamber for assaying, analysis and hallmarking jewelry and other products made of precious metals and precious stones without non-metal parts.
