The large candle holders have a round shape formed with a diamond pattern in the navy blue glass, giving them their unique geometric shape. As a result, you can use them to hold tealight and votive candles or use them to hold flower arrangements like a vase. Fashioned from mercury glass, both candle holders in the set are a dark navy blue with an underlying silvered hue for added accent. The speckled effect this causes on the colored glass lets varied levels of candlelight shine through.
