Magnificent Cobalt Blue Controlled Bubble Vase / Candle

This is an extremely well made piece of controlled bubble crystal. It is cobalt blue and clear glass, and very heavy and thick. It is layered glass and can be used for either a candle holder or a vase. The vase end is sanded or ground smooth. It measures 14.25 inches high and and 4.25 inches across. It is in excellent condition. I do not know the age or maker, it is an unmarked auction item, but the quality is masterful.
