Quality control

Each Dukachi jewelry piece undergoes hallmarking at the state assay office, which serves as official confirmation of the authenticity and purity of the precious metal - specifically 14k gold, 18k gold and 925 sterling silver.

The tag attached to each piece of jewelry serves as its official passport and includes details such as the metal, fineness, weight, gemstones, and their characteristics.

We use high-quality diamonds selected according to the international 4C standards (cut, color, clarity, and carat weight). 
Jewelry featuring a single diamond weighing 0.25 ct or more is accompanied by a certificate from a gemological laboratory (GIA, IGI, or equivalent).
