Blue Art Glass Vase with Air Bubble

This is a blue art glass vase with a transparent thick base into which a large air bubble has been blown. The opening is still there in the base. The vase tapers as it goes up. This piece measures approximately 10 3/8 inches high with the base being about 2 3/4 inches in diameter. It is very heavy. This vase is a gorgeous colour. In certain lights it is sort of an aqua colour (see pics) and in less bright light it has more of a navy or dark blue look. This vase is in very good preowned condition with no chips or cracks.
