The singer has cultivated a distinctive look that’s all of her own, defined by her figure-hugging sequin gowns and jaw-dropping diamonds. She even once joked that she’s allergic to fluorescent lighting—that’s how committed she is to her fabulous, diva-worthy aesthetic. It was only a mater of time, then, before Carey began designing her own jewelry pieces.
