Antique art glass salt cellar, hand blown two way swirl

Here is a very unusual salt dip. It appears to be hand blown and has a ground and polished bottom. The outside swirls to the right and the inside swirls to the left making it look like a diamond pattern of sorts. It has a touch of opalescence and the swirls have a light dusting of gold. Measures 1 1/4" deep and has a diameter of 2 3/8". Hard to catch the odd coloring in the photo. Perfect condition with no damages
