Correction - just checked Dog River Glass company and found this
The one Dog River jar that I have handled (different mold) had a very green tint to the glass (a typical Millville jar would be blue aqua not green aqua)
BUT
I would really want you to have an experienced collector examine this in person to give you a reliable opinion. Even a very clear photo may not be enough to tell the difference.
