This is a very pretty design that includes an 8mm bezel set cultured pearl cabachon in an openwork circle with art nouveau styled floral embellishments. The bail is attached and fixed in one position.  The setting is gold tone and may be very lightly gold plated.  The design is very delicate and feminine and the nacre of the pearl is very beautiful with an irridescent sheen of pink and green. This pendant is from an estate and while it is neither gold nor Victorian, it is likely a Victorian Revival piece circa 1940's - 50's.  The circle of the pendant is 3/4" in diameter.  A 17.5 inch replacement chain is included.
