Here is a lovely Sterling silver knot brooch, which I think may have been made by the Danish minimalist Arne Johansen (see bio), but I am not sure. The low price reflects my doubt, rather than the quality of the piece.
Condition: Excellent, no visible damage, rollover safety clasp
Marks: AJ, UK import marks for 1972
Size: 5.5 cm (2.2") across)
