This is a signed, silver-coloured, white metal pendant by Trifari, the well known the American costume jewellery maker.
It's a strong design of five concentric ovals, cast in one piece fixed and fixed to a bail at the top. On the back is the Trifari signature.
The cable link chain runs through the loop of the bail and is about 30cm long (12 inches). Hanging from the chain's first link is the Trifari Crown "T" tag. The tag and signature date the necklace between 1955 and 1969 and the style of the pendant would match the late 1960s.
The mannequin dress form in the pictures is around size 10-12.
