This comes from the French words “bizou” (“finger ring”) and “biz” (“finger”). In English, “bijou” can refer to a small jewel or trinket, but it’s more commonly used as an adjective to describe small, charming, and elegant homes or businesses. A boutique clothing store or exclusive art gallery could be described as bijou, as could a picturesque cottage or perfectly designed studio — all different interpretations of “small and elegant.”
