Gorgeous pair Heavy Glass Candleholders

Beautiful set of 2 Glass Candle Holders. The larger one is 3.5" tall and the smaller is 3" tall. Very heavy glass with an iridescent tint. Larger is a gold color, smaller a blue/gray. ( the color changes and reflects in in the light) These are new. I received them as a gift and have not used them. My pets are too curious.
