When jewelry designer Neil Lane first met Bachelor Sean Lowe in Chiang Rai, Thailand, last March, it was mere hours before Lowe’s teary-eyed proposal to Catherine Giudici on his season’s show finale. Yet Lowe — who chose a vintage-inspired, 3.15-carat diamond engagement ring that day — was the picture of calm.
“Of course Sean was excited, but he was so certain he’d found the love of his life that he was pretty relaxed,” recalls Lane. Fast forward about 10 months, when Lowe and Giudici stopped by the jeweler’s L.A. store to pick out wedding bands for their Jan. 26 nuptials. “Sean was the same guy – excited, sincere, committed and certain of his choice in Catherine — and eager to find the perfect rings,” Lane tells PEOPLE exclusively.
