She may be a demanding pop diva, but Mariah Carey is now a demanding green diva. Mimi's secret wedding to Nick Cannon included a $2.5 the million re-gifted ring . . .the same 10-carat platinum and pink diamond engagement stunner that he gave his first fiance, Victoria’s Secret model Selita Ebanks. Lucky for Nick that Selita gave that baby back. Whew!

Memo to Mariah and Nick: There’s enough precious metals already mined to meet demand for next 50 years, so CGG applauds your decision to go with recycled jewelry!
