This is a beautiful large vintage 1980s gold toned Christian Dior classic logo brooch in a rounded design, the entwined Dior letters being set within & just overlapping the "C" for Christian & measures exactly 6.3cm 2.4" in diameter. 

Finished in a high-gloss almost mirror finish bright Aztec gold, Parfums Christian Dior stamped into a raised narrow band to the back, the pin is nice & sharp with no damage & is only ever so slightly bowed. 

It is simply beyond rare to find one of these in this as good as untouched condition.

 ( I recommend you measure against other brooches you own to give an idea as to the size )
