Natalie Portman's stunning engagement ring is just as blinding as every other Hollywood "it" girl's, but leave it to the devoted vegan to flash an eco-friendly sparkler with an estimated value of $35,000.

Expectant Portman's ring was carefully designed by dancer-model fiancé Benjamin Millepied to include recycled platinum, an antique center stone and accenting pavé diamonds taken from a conflict-free mine, InStyle reports.

The ring was created for the couple by Jamie Wolf, a ballet dancer turned jewelry designer who collaborated with Millepied on the vintage-inspired statement piece.

"Ben was exceptionally thoughtful and dedicated and patient to make sure we had everything right," Wolf told the mag. "We wanted everything about the ring to speak to things that are important to Natalie."

Every element of the ring, from the recycled metals to the antique center stone, reflects Portman's preference for eco-friendly choices. The pavé stones' conflict-free certification means no one was hurt or treated unfairly in their mining.

Ashley Mendel Fox, a designer and vintage gem expert with New York City-based Camilla Dietz Bergeron LLC, calls Portman's ring: "a wonderful example of a classic design with a modern twist."

She explains the ring reflects a growing trend of placing antique stones in modern settings for a couple's romantic version of "something old" for their wedding day. In the case of Portman's ring, the older center stone, when combined with the new pavé stones, "really makes the ring pop."

The Oscar-nominee, expecting her first child with Millepied this summer, is known for opting out of leather shoes whenever possible and making conscious choices about what she puts in and on her lithe body. She briefly launched a vegan shoe collection that folded in 2008.

As for the meaningful ring: "I was really proud of how it turned out. It's gorgeous," Wolf told the mag. No surprise, a pleased Millepied helped his jeweler friend arrange a "Black Swan" cameo.

While the ring is a true gem, not everyone was as impressed with Portman's recent Golden Globes dress.
