This is one of the hand blown Italian bottles. The stopper is the correct stopper for the bottle. It is a beautiful blue it’s lighter than a colonial blue. There is a prominent air bubble pictured. I have collected decanters for a long time and it is harder to find the taller handmade ones compared to the shorter mass produced ones. The last 2 photo is for reference of color and size only, 1 BLUE SMOOTH BOTTLE, is for sale in post.
