Meticulous workmanship is evident in every aspect of this 1920s Art Deco onyx, diamond and platinum brooch.

From the extraordinary shaped and curved graduated stones through to the mounting and setting, this is a superb example of craftsmanship.

I can see this pin complementing diverse jewels including niello, jet and cut steel pieces, as well – of course – as making a wonderful statement all on its own.
