This is an English art glass vase, produced towards the end of the 19th century to the beginning of the 20th century, so circa 1900.
The vase is 4" high and 5 ¾" wide at the belly.
The shape of the vase is a round bowl with a folded down mouth that has a double crimp in six places around the rim.
The interior glass is an iridescent white opal. There is a clear glass outer layer that can be seen clearly at the bottom. The outside has an applied green glass trail that winds around the belly multiple times.
There are no chips, nicks or cracks. There is a little discoloration on the inside of the vase towards the bottom, and one small popped air bubble.
The pontil is round, slightly indented, polished smooth, but with some pontil break-off roughness remaining in the center.
