A beautiful 1970s style choker necklace... It is a tension-sprung choker with a large statement spiral pendant. I believe it's silver-tone cast metal but it looks like silver with a good silvery shine (untested). The wires have a hammered finish throughout, reflecting the light and looking handmade.  
It's a fun statement piece and is retro/modernist and boho hippy-chic in style. It's a 5" diameter circle and is 39cm long. (Please check this fits, not adjustable). The choker component is round in shape, with tension sprung hook-over front fastening. The spiralling pendant is large and sits flat - 11cm x 5cm, with loops the drop extends to 12.5cm long. Unsigned with unknown vintage and origin.
Very good condition. Quite a statement and a perfect gift idea!
Price includes P&P to the UK. (Too big for my presentation boxes, so will be wrapped).
