This set is made of fine lead crystal. I have owned this set for over 30 years. The pattern is similar to Waterford, but I cannot find the acid e tched Waterford mark anywhere so I believe it is from a different maker. This set is fabulous and flawless. The decanter with the stopper inserted is 11.5 inches tall. The decanter without the stopper is approximately 8.25 inches tall. The decanter has an 8 inch base. The stopper is original to the set and is approximately 4 inches long. The decanter with the stopper inserted weighs 5.8 pounds. The four glasses are beautifully cut and match the decanter. The glasses have a diameter of 3.25 inches at the mouth and 3 inches at the base so there is a slight flare. The glasses are 4 inches in height.
