Vintage Cobalt Blue Crystal Vase /Clear Base With A Floating Bubble

Elegant blue glass vase. Unique round vase or tealight candle holder with a clear bottom containing a floating bubble. Measures 5" H. No chips or cracks. A few small bubbles in the glass and a popped bubble but not out of the ordinary for blown glass. See last photo. It is not signed but has a high end modern look and appears to be hand blown.
