The lock for a necklace from test silver 925 with gilding, 7 mm

The original lock for a necklace in the form of a "ball" from test silver 925 with gilding, 7 mm. The detachable part of the lock is inserted into the ball until it is fully locked. If the lock is unfastened, the safety eye will not allow the necklace to fully open. This lock is ideal for necklaces and pearl necklaces, as well as for necklaces of any other semiprecious stones that have a spherical shape of beads.
