What does chatoyant mean?
Chatoyant describes a distinctive kind of shimmer: a luminous band of light that appears to glide across a surface as the angle of view changes, much as light seems to slide through a cat's slanted eye. The word is most at home in gemology, where it names the prized optical effect seen in stones such as tiger's-eye, chrysoberyl cat's-eye, and star sapphires, but it also lends elegance to descriptions of silks, lacquers, feathers, and water. Chatoyant derives from the French verb chatoyer, meaning to shine like a cat's eye, ultimately from chat, "cat." Formal and literary rather than conversational, the word carries an admiring connotation of richness and depth. Its noun form, chatoyance, refers to the shimmering effect itself.
adjectiveShimmering or changing color and luster as light plays across the surface, like the eye of a cat; having a shifting, iridescent gleam.
- (Of minerals, gems, textiles, or other surfaces) exhibiting a luminous band of reflected light that shifts as the angle of view changes; shimmering like a cat's eye.
- More generally, glittering or flashing with changing luster or color.
"The chatoyant surface of the tiger's-eye stone seemed to glow and ripple as she turned it in her hand."
"Under the jeweler's lamp, the star sapphire displayed a strikingly chatoyant streak of white light."
"The silk had a chatoyant quality, its sheen rippling between bronze and violet as the model moved."
The word literally comes from French for "to shine like a cat's eye" — so when jewelers talk about chatoyant stones, they are quite literally describing something that gleams like a feline's gaze.

Etymology of chatoyant
Chatoyant entered English in the late 17th century, borrowed from French, where it is the present participle of the verb chatoyer, "to shine like a cat's eye." That verb is formed on chat, the French word for "cat," which descends from Late Latin cattus. English cognates sharing this Latin root include the familiar "cat" itself and related animal words such as "caterpillar."
