This seems to have some age, and has some inclusions, mostly bubbles. No markings on the bottom but the six sided star is cut and polished on the top of the base.
7 inches tall, 3 ½ across at the top and the base is 2 7/8. The pattern has been cut and polished. There is no mold line on the bowl but the stem has three mold lines. It has a ring when tapped but not a real clear note. It has a safety rim.
