Red Diamonds are Beautiful, Rare and Becoming More Expensive
Rio Tinto's Argyle mine is producing red diamonds that are increasing in value, according to Robb Report.
The rarest and arguably most beautiful diamonds - those from the Argyle mine in Western Australia - will only continue to grow in value, according to experts. The mine, which produces pink, red and violet diamonds, is expected to be depleted in 2020, according to Jill Newman, executive editor of Robb Report. According to the magazine, the value of Argyle diamonds has "significantly outperformed several major indexes," including the Dow Jones Industrial Average and S&P 500. The Argyle mine is owned by Rio Tinto (RIO) - Get Report .
