I'm not sure who made this pretty purple amethyst blown art glass vase. It has a semi-crimped rim with melon rib interior optics, measuring 5 inches high by 4 inches across the longest side of the rim. The glass is fairly thick but not overly so, and the underside has a pontil scar if that helps to identify possible makers. The vase is in excellent condition with no damage, cloudiness, or water sediment.
