Aubergine Pearl has all of the typical features of a Pearl, with a thin and flexible build and a pointed beak-like nose. She has lilac skin and violet colored hair that is styled into a bun. Her eyes are significantly different than that of other Pearls, being more slanted. Her outfit is also unique from that of other Pearls; rather than resembling a dancer's costume like theirs do, hers is more reminiscent of a guide's uniform. It consists of a cap sleeved charcoal grey shirt worn over a white mock-turtleneck. She also wears a pair of dark purple, high-waisted leggings as well as a pair of white boots. She wears what appears to be a nametag of some sort on the right side of her shirt. Her gemstone, a dark purple cabochon pearl, is located on her forehead (like the Crystal Gems' Pearl).
Not much is known about her personality, aside from the fact that she appears to be very knowledgeable about Homeworld's former society.
