I wouldn't be surprised if everything Kate Middleton touches turns to gold, after all, everything she wears becomes an instant trend. As soon as she began sporting an 18-carat sapphire stunner complete with a halo of 12 diamonds, brides everywhere wanted a matching blue beauty. Five years later, that hasn't changed. And today, we're majorly crushing on this custom Lauren B. engagement ring that's giving us major Kate Middleton vibes. Trust us, it's enough to make any woman feel like a queen!
