Argyle pink diamonds get heart of stones beating

Rare pink, red and blue Argyle diamonds.
IF diamonds are a girl's best friend, to use the well-known refrain, then a pink diamond is a soulmate - an exceedingly rare find. It was certainly the rarest of finds for global mining giant Rio Tinto in 1979 in Smoke Creek in Western Australia's Kimberley, a region of rugged yet breathtaking terrain.
Exploration crews were working their way along that creek on October 2, 1979, when one of the geologists saw a small diamond embedded in an anthill. Thus began the start of the Argyle diamond mine and a multi-billion-dollar industry.
Diamond enthusiasts marvel at the sparkle and attraction of a white gem, but the precious pink stones are truly unique and they comprise less than one-tenth of 1 per cent of Argyle's annual diamond production.
