Image of a 'possible' Moser decanter
"This piece is in a Rich Emerald Green Color with Beautiful Raised Floral and Gold accents in the design. Heavy 24K Gold Accent on this piece. There is some wear to the gold on the raised lid handle and some throughout the piece. Also there is an indentation on the base of the piece which is from the clamp that held the piece when it was hand blown.
We are not quite sure but this looks like Moser Glass. If this is Moser, it would have been created in the early 1900's. This piece came out of a Gothic Mansion in Western Indiana that was built in 1826, so it very well can be Moser Glass.
This item is in excellent shape for it's age.
Measurements:
Ewer: stands 15 1/4 inches tall.
Ewer is approx 4 inches wide."
