Vintage Gold Vase

This vase is about 14 inches tall. It has a raised gold design on the outside of it. I believe that is called Filigree?? Not sure. The inside is smooth glass. When looking at it at a distance it looks like solid gold , but when you look at it through the light, you can actually see through it!! It has been in my family for ages. Was my Grandmothers. She did not use it mush because she did not want to ruin it. But was always on display in her home. She got it as a gift for an Anniversary. Very beautiful vase. Anyone ever see a vase like this???
