Wedgwood Glass Sheringham Candlesticks.

I picked up the blue glass Candlestick today. I've had the topaz one for quite a while, but I was aware that Wedgwood Glass made them with many more rings, but they are hard to find, so I was pleased to find one with 3 rings. The dark blue one seems to be called Sapphire Blue. They are both marked Wedgwood, England on the base.
