Vintage/antique Amber glass with 24 karat gold detailing decanter & 5 cordial

This is vintage/antique? Previously owned, possibly from the 1930s decanter and five cordial glass set. I’ve been told that it is Marano Amber glass hand blown, and the information I can find. Does agree with that, but I am not gonna guarantee that that it is because I have not had it authenticated. With that said it’s a beautiful Amber glass with clear twisted stems on the decanter and the glasses. They are detailed in 24 karat gold. Because of the age, some of the gold has somewhere, but really not much most of it’s on the bottom of the glasses almost all of the gold on the amber glass is still in good shape. Seems to be pretty much all there but the rim on the bottom does show some ware. From what I could find the gold on these glasses is much better than anything I found online. They’re really beautiful. The glasses measure 4 1/2 inches high and the decanter is just over 12 1/2 inches. I am going to add extra weight so that they can be Packed extremely well. The glass is very thin.
