Dia is a member of Ishigami Village. She is the wife of Alabaster and the mother of Ruby, Sapphire and Garnet. She has long blonde hair that drapes softly over her shoulders, parted towards the left side. A few of the front segments are slightly shorter and fall across her face. She has thin eyebrows that taper towards the outer ends with a high arch. Her eyes are heavy-lidded and have a single eyelash coming out of the ends, giving her a seductive cat's eye look. Her lower lashes are also quite thick. She has a small button nose and very full lips, with her lower lip larger than her upper one. She has slight smile lines around her mouth, giving her an air of mature elegance.
