This is a vintage costume jewellery pendant in silvertone that would date back to the 1960's.
It is abstract in design and to me it looks very similar to an owl on its perch! The pendant is articulated in 3 places. It is made up of diamond shapes and is really beautifully made. There is no makers mark that I can see.
There are 7 rows of diamonds making the piece measure 13cm long which includes the bail and the silvertone chain tassles that hang from the end.
The chain is a textured and has a medium size link and measures 60cm. It is in excellent condition.
