Rio Tinto Copper & Diamonds vice president of sales and marketing Mr Alan Chirgwin said “I am delighted to be in
New York, the epicentre of the fancy coloured diamond industry.

“It is 40 years since the discovery of Rio Tinto’s Argyle mine and it remains the first and only ongoing source of rare
pink diamonds in the world, in history. With the lifecycle of this extraordinary mine approaching its end, we have
seen and continue to see, an unstoppable demand and strong value appreciation for these truly limited edition
diamonds.”
