Garniture is a fancy word for accessory and deals with embellishments and decoration. In vogue from the seventeenth to the nineteenth centuries, a garniture is a collection (usually odd-numbered) of matching, unidentical, decorative objects displayed together usually on the mantel shelf of a chimneypiece. Usually, these are made of metal, ormolu, with gilded wood stands, porcelain, etc
It’s where the word garnish comes from as well.
This is an archaic word and seldom found in literature:
“She was made to sparkle, to be bright with outside garniture, — to shine and glitter, and be rich in apparel. The only doubt might be whether paste diamonds might not better suit her character.”
― Anthony Trollope, Complete Works of Anthony Trollope“Above the fireplace: a scene of a cow jumping over the moon, in an elaborate gilt frame. On the mantle below, we see a clock…, flanked by garniture sturdy enough to be a murder weapon out of Agatha Christie.” — Rumaan Alam, Slate, 23 Aug. 2016
