Both sexes have a straight bill with a blackish maxilla and a pinkish mandible with a dark tip; its length varies among the subspecies. Adult males of the nominate subspecies C. f. fimbriata have golden- to bronze-green upperparts and a dark bronze-green to blackish bronze tail. Their throat and most of their breast are glittering golden-green. The center of their lower breast and their belly are white and their undertail coverts white with brownish centers. Voice: The glittering-throated emerald's song is "a continuously repeated, single, high-pitched buzzy note, 'tzee...tzee...tzee...'" that is usually given at dawn. It makes "a repeated high thin 'tsee…tsi-tsi-tsitsitsi'" or "tslee-tslee-tslee-tslee" in flight and during agonistic encounters. Its calls include "high-pitched 'tsee' notes and soft chatters".
