Resembling, set with, or full of gems; gem-like in appearance.
From gem plus the suffix -y (characterized by, resembling). This descriptive adjective emerged in English to poetically describe glittering or precious things.
Victorian writers loved the word 'gemmy'—it made ordinary nature sound magical! Describing frost as 'gemmy' or eyes as 'gemmy' gave everyday things a luxurious, sparkling quality without sounding ridiculous like some poetic words do.
