Ariana Rockefeller | Net Worth: $2.8 billion

Source: Standard Oil

Ariana Rockefeller is an heiress who comes from very old money. As you might already know, the Rockefellers have been very wealthy since the 19th-century. She is the heiress to Standard Oil, which was established by her great-great-grandfather. This alone will give her $2.8 billion, which means she doesn’t have to work a day in her life. However, following her parents’ steps, the heiress isn’t averse to using some of her investment money toward various ventures.

For example, in 2011, she launched her own fashion collection and even had a pop-up store in Manhattan’s SoHo neighborhood. It might surprise you to learn that some of the proceeds from this business also went to the charities she supports, such as the Humane Society. On top of that, she also serves as part of the Board of Directors for the David Rockefeller Fund.
