Cobalt frosted glass swirl bud vase

Hello again, hopefully someone will be able to help with some information on this frosted glass bud vase. Maybe it is just a generic piece, but I can't find one similar, other than one with an hourglass shape. What sort of sets it apart is the "swirl" design that wraps around the length of it. Also, the bottom, or base, is much darker than the vase itself. It stands 11 inches tall and is not marked in any way. Thanks in advance for any thoughts or ideas.

 

I think its lefton japan. Here is one on ebay same design and shape but lighter color.

 

Thanks so much, It looks like you nailed it. For being an inexpensive piece, it looks fantastic in natural light. The blue glows and those "swirls" or whatever they are called really stand out. Thanks again!
