Mary-Kate Olsen has yet to confirm the rumors that she is engaged to beau Olivier Sarkozy, but yesterday she stepped out with a large diamond ring on her left hand, which, of course, only added fuel to the fire.
But before we get ahead of ourselves let's breakdown what do we know about this new sparkler. According to Zaven Ghanimian, Marketing Director of Simon G. Jewelry, the bling is very unique."Mary-Kate's ring appears to be an 18-carat yellow gold vintage design. The round, oval center stone is either a rough-cut gray or white diamond."
Sure, the Olsens are fashionionista, but we doubt even Mary-Kate casually walks around with a massive diamond on that finger. Of course, this is all speculation. Her boyfriend of two years is a successful French banker, after all, so it could just be a really, really nice gift. Though, we kind of doubt it. Especially because sources told E! News in December that the very in-love pair were considering marriage and that Olsen was "crazy for Olivier."
Add that with the knowledge that the couple currently live together in a $6.25 million NYC townhouse—seems to be a pretty committed relationship to us.
