The "Dark Jewelry Star Bracelet" is a dark and alternate version of the Sailor Guardians' Jewelry Star Bracelet. It was used by a brainwashed Ami Mizuno/"Akumi" to transform into Dark Mercury. She would transform by saying "Dark Power, Make Up." It was different from the other Bracelets because the heart part and the round ones were blue and in the other ones it was pink and the heart was red and the outer side was white.
