The World's Richest Women of 2013

More women have joined the ranks of the world's wealthiest, but as a group females still hold a small sliver of total 10-figure fortunes. Of the 1,426 people on the new 2013 Forbes list of the World's Billionaires, just 138 are women. That's up from 104 women last year. New women billionaires include fashion designer Tory Burch and Hong Kong finance executive Pollyanna Chu.
