Rio Tinto's Argyle diamond mine in the Kimberley region of Western Australia is the World's premier, and only consistent, producer of rare pink diamonds. This particular pink diamond, found in July 2012, is the largest pink diamond produced by the Argyle mine. When it started to be faceted a flaw was found that would have caused it to break into many pieces if cutting continued. Instead of continuing with the cutting Rio Tinto decided instead to preserve the diamond it in its partially polished and cut state and donated it to Museum Victoria. Before cutting the Argyle Jubilee Pink Diamond was nearly 13 carats. It is now almost 9 carats.
