Pink Diamonds Come and Go.

Pink diamonds from the Argyle mine in Australia are simply spectacular to look at.  The owners of the Argyle, Rio Tinto say the mine will play itself out by 2018.  Meanwhile, the 43 Argyle pink diamonds have been put up for sale and buyers from China and India have been snatching them up with the idea that hard assets are the best investment.  The top stone pictured right is 1.25 carats, the middle oval stone is 1.10 carats and the heart shaped stone is 2.61 carats pictured at the bottom.  The diamonds are pink because of the contaminant, most likely iron.  Unfortunately, this years' lot has been sold.  Better luck next time.
