Antique glass spoon or celery holder. It is 6 inches tall so it could be either one. It glows a strong yellow under a black light which means it was likely made before 1916. It has a couple of tiny glass flaws that are within the glass; an itsy bitsy chigger bite on the bottom rim, and a bubble in the glass, but those are hard to spot. The glass is nice and clear, not cloudy. The only evidence of age other than the yellow glow under a black light is the aged bottom rim. A lovely piece to use or just display! 10/15
