This article is dedicated to study of the jewelry craft of Staraya Ryazan’. It has been prepared for the 200th anniversary of the discovery of the first hoard there (1822), which marked the beginning of the study of ancient Russian towns, the most important area in the science of Russian antiquities. The marks of the individual style of a craftsman who served representatives of the princely family (interpretation of the images of animals, birds, anthropomorphic figures, and elements of ornamentation, as well as features of the technique) are considered. Jewelry made by him was found in four hoards (1950, 1966, 1970, and 2005). The hoard of 2013, in addition to jewelry, included raw materials and tools of the jeweler (bronze matrices). The number of the matrices indicates that they were intended for several workshops. Some data show that a large grand ducal jewelry workshop was located near the place of the find.
