Contemporary moderne graduated blue green honeycomb etched satin glass 10" vase

Contemporary moderne graduated blue green honeycomb etched satin glass 10" vase. Hard for me to tell how old this is it's a nice big chunk of glass approximately 10 inches high and it has a large round pontil on the bottom (photo later) and the pontil is not smoothly finished however it's also satiny finished on the inside of the concave pontil... not buffed clean and shiny like an Italian piece of art glass would normally be but then I've seen this type of glass with the same colors and treatment listed as five different kinds of glass so I can't really categorize it. At first I thought it was from China and maybe sold through a home's good store and now I'm seeing it could be Italian art GLass ? When you buy a vase in a second hand store you obviously don't have a lot to go on especially with no markings or signatures. Having said all that it's in mint condition and it's just absolutely drop dead gorgeous and if I were to keep it I would make sure I had it near a window.
