JG Durand crystal candlestick candle holder reverse hobnail glass depressions

This is a candlestick marked "JG Durand Crystal" on the bottom. This stands 4 3/4 inches tall and is 1 3/4 inches in diameter. It has a reverse hobnail pattern with circular depressions in the glass that make it look like polka dots. The piece is solid crystal and weighs over a pound. There is only one of these. It is in great condition with no chips, cracks, flea bites or scratching but there is a small surface mar. The mar looks like a bubble was trapped inside the glass during pouring and then the air escaped leaving a circular imperfection with a center pinpoint hole. This mar is about 1/8th inch in diameter.
