This is an impressive antique Art Nouveau ring in sterling silver set with a large rectangular onyx stone. The setting is ornate and features female figures on either side. The stone is onyx not glass and has been tested with a gemstone tester. It is not marked for silver content but has been acid tested.
The ring is a size 4 and the face of the ring measures just under an inch north to south. It is in very good condition, however the stone is a little loose. It appears to be secure.
