Some traditional jewelry techniques (for example, filigree or filigree, as well as blackening) are “by ear”, but not widespread enough to immediately find out if it is for sure. Using this superficial acquaintance of buyers with technicians, sellers can call their names cheaper methods of decoration, thereby increasing the value of the product in the eyes of the client. True filigree is made only by hand by unfolding a pattern of thin wires and baking in an oven. In jewelry retail, “filigree style” products are more common — less delicate openwork items made by casting (for more details, see the article on filigree technique).
Blackening is also a time-consuming and "spot" procedure, in contrast to industrial techniques for dimming products (the same oxidation or rhodium options). If you understand the technique of blackening, then a real blackened product can be easily distinguished by eye (for more details, see the article on blackening silver).
Another similar area is enameling: not everyone immediately distinguishes hot (more labor-intensive, expensive and “wear”) enamel from cold. It makes sense to understand the properties of different types of enamel jewelry to at least buy what suits you best (more about hot and cold enamels).
Manufacturer and place of manufacture
On the market you can find many brands that sell jewelry under the famous Soviet or beautiful Russian names. It seems that the products continue to be produced at the same domestic enterprises as before, but this is not always the case. If you prefer the jewelry to be made in Russia, carefully read the information on the manufacturer on the product tag. Often in Russian-sounding manufacturers order jewelry manufacturing in China, Taiwan, Hong Kong and other countries.
Jewelry manufacturers supply their products to various salons and retail chains for sale. On the sites of some jewelry factories, a barcode check is implemented. It is enough to drive the numbers from the barcode on the jewelry tag, and you will be provided with complete information about the decoration parameters.
Documents when buying jewelry
When buying jewelry in ordinary salons or online stores, you must provide the following documents:
the sales receipt on which should be: the name of the goods and the details of the seller, the sample, type and characteristics of the gemstone, article, sale date and price of the goods and the signature of the person directly selling the product
the jewelry itself with a tag (label) attached to it. The tag is a kind of product passport, and its filling is regulated by regulations. The tag must be attached to the product with a thread and seal
Will they give a certificate for a stone insert?
Unrefined (i.e., not included in jewelry) faceted diamonds made from natural diamonds and faceted emeralds are sold only with a certificate for each stone or set (lot) of stones sold.
For any stones in the jewelry, a certificate is not required, it is replaced by a tag. Certificates can be ordered by the gemologists themselves jewelry enterprises, but this procedure is not cheap, and this is done infrequently.
