Despite what some of his detractors may think of his music or his taste for rap beef, the purchasing power of 50 Cent is undeniable. His deals with Reebok, Ecko, Coca-Cola and Right Guard have landed him a spot as Hip Hop's reigning cash king [click to read]. Now Forbes reports 50 may expand his considerable fortune even more by moving into the jewelry industry. South Africa's Patrice Motsepe has been meeting with the G-Unit capo for over a year.

Motsepe owns African Rainbow Minerals Limited, a mining and minerals company with an estimated net worth of $2.5 billion. When 50 was spotted with Motsepe at one of his mines, he refused to directly address the rumors only stating that he was there for, "things that people wouldn't actually expect me to be involved in."

Both Forbes and Advertising Age speculate both men have designs on a joint venture to create a signature line of platinum jewelry bearing 50's name. 50's response? "I got a diverse portfolio."
