It's hard to decide which is more surprising, Eva Longoria's announcement that she's engaged or the ring fiancé, Jose Antonio Baston, chose to propose to her with!

If her Instagram caption was any indication, Eva Longoria was completely floored this weekend when her longtime boyfriend, Jose Antonio Baston, popped the question. She posted a romantic photo of them both that read, “Ummmm so this happened….#Engaged #Dubai #Happiness

The only thing more unexpected than Baston’s Dubai-set proposal? The unusual (and huge!) ring he did it with.

Judging from the Instagram, this is no traditional halo-set giant Hollywood diamond. Instead, Baston appeared to have selected something much more surprising, but with the same eye-catching mega-carat brilliance. The ring looks to be a substantial ruby surrounded by clusters of smaller diamonds, which coincidentally coordinates perfectly with the Telenovela star’s bright orange dress.

And Baston isn’t just great at choosing rings — he’s also a fabulous partner for Longoria. “I’m excited to be with someone as kind as Pepe is,” she tells People. Adds a source, “Eva is over the moon to have finally found her Prince Charming. Pepe has completely swept her off her feet.”

While rubies are still fairly unexpected these days for proposals, the stone seems to be gaining popularity among stars – both Simpson sisters memorably sport rings featuring the vibrant gemstone. And considering the sapphire craze that occurred when Princess Kate got engaged, we wouldn’t be surprised if Longoria kicked off a whole new bride-to-be trend.

What do you think of Eva Longoria’s engagement ring? Do you like the style or prefer something more traditional?
