GEOMETRIC BROOCH - TRIANGLES IN RED, GREY AND BLACK

I just love geometric designs but do not see a lot of  jewellery in good modernist shapes.  This brooch is not an expensive one - made out of relatively cheap material - in grey, red and black.  Probably made by hand.  It is just that the design is - in my opinion - so good. (not sure of the material or the age).

Resin Geometric Brooch - Red Grey Black Triangles I would be happy to wear it.  Wish I could find more like it.  Price £38 reference 3004 C39/36
