The 30-year-old Black Swan actress and her 34-year-old dancer/beau debuted their wedding bands at the 84th annual Academy Awards on Sunday.

Jeweler Jamie Wolf tells the mag:

    "I designed the rings worn by Benjamin Millepied and Natalie Portman. They were made with recycled platinum and conflict free diamonds."

The couple met on the set of Black Swan in 2010.

Last June, the Oscar-winning actress gave birth to their son Aleph.

Natalie's rep has yet to issue an official statement.
