Materiály a výroba


The basis of ADDA jewelry is textured 925 sterling silver.
  • 925 sterling silver means that the alloy contains 92.5 percent pure silver, and the remaining 7.5 are alloy metals (copper, nickel, zinc or platinum). Silver jewelry is complemented with gilding, goldfield, and blackening.
  • Gold plating is a coating with a gold layer thickness of 0.5 - 8 microns, applied to the surface of silver using electrolysis.
  • Gold-filled - coating with a thickness of 10 - 120 microns. An important difference between goldfield and gold plating is the presence of an intermediate layer between the gold and the base metal.


ADDA cooperates with stone suppliers from Israel, China, India, Thailand and other countries. The collections use minerals mined for us from rare deposits in the Urals, Transbaikalia, and the Kola Peninsula. Only natural stones, not refined in color, in which their unique beauty is preserved: cabochons and druses.

  • А cabochon is distinguished by a smooth convex polished surface without edges. Each cabochon is processed by hand by talented craftsmen.
  • A druse is an unprocessed natural formation of an accumulation of crystals on a bed of rock.

The so-called identification marks reveal the origin of the jewelry. These can be of two types. Each goldsmith or company that manufactures jewelry and is registered at the hallmarking office has its own unique form of mark, which is called a production mark. If it is an entity that imports or buys the jewelry from abroad and then sells it in the Czech Republic, it does not avoid the stamp duty either. The stamp office assigns it a responsibility or import mark.
Eden Gems carries the EDG responsibility mark.

Silver jewelry exceeding the legal weight of 3 g is marked with the responsibility mark of the importer or Czech manufacturer, the quality mark 925/1000 and is registered by the Stamp Office. The hallmarking office marks the jewelry with a hallmark that guarantees its purity and authenticity.

When choosing jewelry, it is important to pay attention not only to the design, but also to the authenticity, which is declared by hallmarks.
