Women entrepreneurs continue to reach unprecedented heights. The top 60 richest self-made women are worth a combined $71 billion, a 15 percent jump from 2017, according to a Forbes

This explosion in wealth has made landing a spot on the list more difficult: The minimum net worth of top earing women is now a record $320 million, up 23 percent from last year. Of the 60 richest women entrepreneurs, 24 are billionaires, another record, and up from 18 women billionaires on last year's list.

Some of the stories behind the women on the list demonstrate how business savvy and hard work can lead to riches. Eren Ozman, who is the majority owner of aerospace and defense business Sierra Nevada Corporation, is a native from Turkey who arrived in the U.S. in her 20s. She juggled multiple part-time jobs while in business school. She sold baklava at a bakery, and held even held a job as a janitor at Sierra Nevada before later buying the company with her husband.

Fashion and retail was a particularly popular industry among the Forbes list of richest self-made women. Seventeen women built their wealth in these industries. Billionaire Anastasia Soare is the founder of Anastasia Beverly Hills, a company best known for eyebrow enhancing make-up. She’s the richest of seven newcomers on the list, with an estimated net worth of 1.5 billion, according to Forbes.

Several notable women have dropped off the list. For example, Diana Von Furstenberg, fashion designer and founder of DFV fashions, experienced a decrease in sales, resulting in store closings, a drop in valuation.
