Anyone? I'd love to know something about this Vase, thanks!!!!

I know this vase is at least 50 years old, given to me by my late Grandfather, it is very dark purple, with a irridesant colors and swirls of gold, there is gold trim on the top, and bottom. It's in perfect condition, no nicks, or scratches. It is 6 1/2" high, the opening is 7 1/4" wide. The bottom has the number 120, and the word WARRANT, and it looks like c.2 CARAT GOLD, printed on it. , I'd love to know something about it, who made it, what it's worth, any history, thank you!!!
