An experimental jewelry laboratory was established at the Gosznak Research Institute in 1965. In 1970 it was transferred to the State Depository of Valuables (Gokhran).
Jeweler Natalya Rostovtseva headed the laboratory for nine years and in 1974 she was succeeded by jeweler Vladimir Sitnikov. Gradually a team of five jewelers was formed and the laboratory operated until 2000.
