Made for: Mariah Carey

"My top ten starts with Mariah Carey’s 'MC' piece, simply because it was the second piece [IF & Co.] ever did. Plus, it was her MC logo. We did it in 18-karat gold, used all VVS1 diamonds, F-color. It was heavy and it was a really nice, majestic piece. We did an 18-karat Franco chain and to this day, I’ve never done another 18-karat Franco because it's impossible to find. She’s worn it here and there. She wore it in some video with Bone Thugs, which is kind of funny."
