A beautiful large modernist/retro asymmetric brooch, by Peak, England. Circa 1960s or 1970s vintage. 18/8 quality stainless steel with a shell.
It's modernist in style, in a curvy long space-age tick or V-like shape. The surface is satin steel and it has a triangular shaped flat abalone shell overlapping it (pearly grey shell tones). 
A good statement size, 73 x 26cm. Roll-over pin to the reverse works well. Very good condition. Can be worn any way round. Perfect retro statement gift idea!
Price includes P&P to the UK. Comes in a card presentation box.
