Vintage Silver Embossed Metal Candle Holder

Part of a collection of similarly made pieces I assembled over the years and styled together. Made to look like sterling or silver plate with patina from age. Pretty embossed details around the base. I’m unsure of the metal content / exactly how to polish. I like this look so all I’ve ever done is clean with Dawn dishwashing detergent. As with all these older pieces I think the patina adds character… This holds a taper candle and stands just over 10.5” tall. The base is approximately 4.75” in diameter. Has a sweet, romantic feel I think… Originally from Pier 1 Imports.
