From the D Kingdom which is the world's largest producer of gemstones. Feels like no one cares about her only her diamonds. Nephrite uses a type of youma called a Soul Shadow to possess her and steal the Silver Crystal. After she was freed from Nephrite's influence, she woke up confused, wondering where she was and where her glasses were, while the Sailor Senshi fled from the scene.
Later she was seen revealing the special treasure, a statue of D's first queen, carved from a single 2000 carat diamond.
Short brown hair and she has poor eyesight so she wears large glasses. When her glasses are off, she is shown to be very beautiful.
