My mom was gifted this vase about 15 years ago. We don't know much about it - would be grateful for any information you can provide?

Answer:

How interesting to get your question, I had two come in at the same time on this line. Your vase is part of the Cascade line by mcCoy, made in 1961. It did come in a couple of different color combinations...IMO, your purple is the hardest to find. It is often found in a redish/burgundy combination as well as a pearlized white finish. There are several other shapes in this line.
