These are not Celtic, it's not likely the Celts wore anything like these, unless they got them in trade or took them off a dead guy. And if the conventional dating is correct, the Celts weren't yet in Europe; the Hallstatt culture is generally regarded as the classical era or "real" Celts. The Irish Book of Invasions records three prior layers of paint (as it were) in the British Isles. I watched a YT vid about Hallstatt culture princely tombs this morning sometime, can't remember the name, this may be similar -- Etruscan grave goods, Greek vase, along with other stuff acquired in trade, plus Celtic-worked gold items; there's a find from about mid-century, also in France I think, which had the largest surviving "vase".
