Mount Washington Blue Mother Of Pearl Diamond Quilt Vase

This is a hand blown ruffled edged blue mother of pearl diamond quilt vase by Mount Washington glass company. There is discoloration to the inside of the vase that I could not get out and a black mark on the rim. Both are pictured. It is 8.5" in height and 5" in diameter at its widest point. I do my best to list any defects an item might have. If you have any questions please do not hesitate to ask.
