Elegant Gold and Clear Glass Candle Holders

This appears to be a pair of vintage iridescent carnival glass candlestick holders.  The glass has a distinctive amber or peach color with an iridescent, rainbow-like sheen that was popular in the early 20th century.  The design features a hexagonal base and a shaped stem, a style produced by various glass manufacturers.  Carnival glass was originally created to be an affordable, mass-produced alternative to more expensive iridescent art glass.
