Carrie Underwood looked like a modern day princess on her wedding day, thanks in part to the gorgeous tiara she wore for the ceremony, and we’ve got the exclusive details on the crowning jewel! The 40-carat (that’s right, 40) 18kt white gold tiara was a wedding gift from hubby Mike Fisher, who worked hand-in-hand with Underwood’s favorite jeweler Johnathon Arndt (he’s also responsible for their wedding bands) on the custom creation. Arndt looked to the Victorian era for inspiration, using both floral and vine designs reminiscent of the period. “This is something you can pass onto your children and grandchildren so they, too, can share that special wedding day,” Arndt told the newlyweds. But Underwood’s penchant for sparkling accessories didn’t stop at jewelry: The bride wore Stuart Weitzman’s “Avalon” heels, which she had custom-designed in Pink Swarovski crystal to match her wedding colors, with her Chantilly lace Monique Lhuillier gown. Although you can’t purchase this exact pair, you can snag a similar style in black or navy. At $675, they’re not the cheapest, but they will add glamour to, well, just about anything.
