"装饰性艺术饰品" can be translated as "decorative art ornaments" or "ornamental art accessories" in English.
"Decorative art ornaments" emphasizes the decorative and artistic nature of the items, suggesting they are designed primarily for aesthetic purposes.
"Ornamental art accessories" also conveys the idea of items that are both decorative and related to art, with "accessories" implying they can be used to complement or enhance other objects or spaces.
Both translations are acceptable, and the choice between them may depend on the specific context or intended emphasis.
