Three-pendant earrings [ser'gi-trojchatki] are made of a round, not closed, shvenzy-ring and three suspension brackets which are made from short, straight metal rods, wound on the shvenzy, and strung with various combinations of cast metal cylinders, decorations of false granules, pearls, beads, drilled semi-precious stones, and mother-of-pearl grains. Trojchatki received a wide circulation since the XVth cent. (Russkoj Traditionij Kostyum. - SPB, 2001, with. 321).
