Sapphire is a member of Ishigami Village. She is one of the three Sparkly Sisters along with her siblings Garnet and Ruby. Her parents are Alabaster and Dia. Sapphire is a young woman with mid-length blonde hair and bangs that frame her face with a single strand falling in the middle. She has downturned blue eyes, heavy-lidded with visible eyelashes on both her upper and lower eyelids, giving her a wistful, doe-eyed look. Her lips are full and plump, and her eyebrows slope downwards, accentuating her expression. Her outfit consists of a short green dress, sleeveless with a ragged hem and a plunging neckline. She wears the village rope around her neck, wrapped twice and tied in the front with a bow. Additionally, she shares a passing resemblance to one of her ancestors, Lillian Weinberg. According to Kohaku, she and her sisters are the prettiest women in the village. Sapphire seems to spend a lot of her time thinking about boys. Out of the three sisters, Sapphire wants a boyfriend or husband who's primarily handsome rather than strong or a provider.
