The shape of this brooch is best described as a mirror image 6 or 9 and I think it would be worn longitudinally and would look great on a coat lapel. It is big enough (8cm x 3cm) to make a statement, especially on a plain dark material. It is modernist and abstraction and its simplicity disguises the pleasing sinuosity of the design in 3 dimensions. It is tactile and very pleasing to the eye. With the reference marks 925 TB 112 all we know is that the maker was based in Taxco and family name beg Names Beginning With B, Victorian Silver Engraved Brooch, Silver Victorian Enamel Brooches, Mid-century Silver Brooch For Collectors, Yellow Vase, Modernist Sterling Silver Brooch, Luxury Silver Art Nouveau Brooch, Dark Material, Silver Brooch
