Green Peridot Halo Engagement Ring

"Jacob proposed on our five-year anniversary," Allison says. "He made me a photo book with pictures of us, telling the story of how we've grown and evolved in our relationship. On the last page he asked me to marry him, and when I looked up, he was holding the ring: a bright green peridot surrounded by a diamond halo. Just over a year later, we got married."
