It is 15.5 to 19 cm (6.1 to 7.5 in) long including the 3.6 cm (1.4 in) bill. Males weigh between 9.6 and 11.2 g (0.34 and 0.40 oz) and females 8.4 to 11 g (0.30 to 0.39 oz). Both sexes have a small white spot behind the eye. Males of the nominate subspecies have dark shining blue-green upperparts. The wing is mostly shining blue and the tail greenish black. The underparts are also blue-green but somewhat bluer than the upperparts. Voice: The great sapphirewing's vocalizations include "a high, thin, liquid chatter", a "drawn-out piercing high-pitched zeee", and " agitated titititirrr".
