Both sexes are dark velvety green above with a small white postocular spot and a dark steel-blue tail. Their lower underparts are dark green with dark gray speckles towards the rear. The male has a small glittering green frontlet just above the bill. Its throat and upper breast gorget is glittering rose to violet and has a white pectoral band below it. Voice: The gorgeted sunangel's song is "a repeated series of 2–3 high-pitched 'pseee' notes...followed by a slightly lower-pitched 'tsip' note." Its call is "a dry chattering followed by a mellow note 'kr..krr..krr..whee..'" and it also makes a high-pitched twitter.
