We all knew Halle Berry's fiance Olivier Martinez had officially put a ring on it, but now we finally have some photo evidence to back it up. Though the couple normally prefer to keep their relationship private, the actress wasn't shy about flashing her stunning emerald rock in front of photographers when she headed out to visit a friend in Studio City, Calif. on March 30.

""The emerald is approximately 5-7 carats, and is estimated to cost somewhere between $100,000 - $200,000,"" Aslam Bakshi, owner of Diamond Images USA, Inc. tells Hollywood.com exclusively. And while the ring is certainly a far cry from the overly extravagant rocks that have come (and gone) from Hollywood stars' fingers, it's still quite a big chunk of change. In fact, there are a variety of different ways Berry could have spent that money and gotten (literally) more bang for her buck.

We just happen to have a few examples...

10,000 Copies of Monster's Ball

Amazon prices Berry's Oscar-winning film at a whopping $10, which means she would be able to buy more than 10,000 copies before collecting her ring's hefty price range. Of course it would usually seem ridiculous for one person to have so many copies of the same movie, but hey, she'd be set on Christmas presents for life, so it's really a win-win.

143 Jimmy Choos

In 2013, Berry is slated to star in a movie called Shoe Addicts Anonymous, where she will play a shoe-addicted agoraphobe who feeds her compulsion by buying online footwear. So it seems almost pivotal for the actress to surround herself with as much foot attire as possible (for research purposes, of course). This money would allow her to buy at least 143 pairs of some of the best shoes on the planet: Jimmy Choos. Sure, it may not seem like a lot, but when it comes to shoes, it's all about quality over quantity. (Am I right, ladies?)

The Batmobile

Okay, so there's no real price tag on the famous Batmobile (most would say it's priceless), but given her past experience with the franchise, having played Catwoman in 2004 (unfortunately), we're sure she'd be able to get some sort of discounted rate. (What do you think - $12,000/life?) This is one feline that is sure hard to say no to. Wait, never mind - millions of movie-goers already did.

Charles Xavier's Mansion

The X-Men school may be for gifted and talented youngsters, but even mutant establishments have a price. Her character Storm was basically running the place by the end of the franchise, so we'd say that's grounds enough to get first dibs. Admit it, owning that mansion would be pretty awesome and way better than any ring. Especially if it comes with a young Magneto.
