"Went on a hike and this happened!" she captioned the photo. "I am so happy to share with you all this exciting and incredible news... the engagement to my dear Ruben!!!"

She's in good company with her unexpected ring hue: Kate Middleton and Olivia Palermo are just a few celebrities who also have colorful engagement rings. (Kate's is blue sapphire, and Olivia's is a yellow diamond.)
