I believe this is a Humidor, but can be a cookie jar or large vanity jar. Made in around 1900s, the flowing flowers and leaves is typical of the Art Nouveau era. The metal is gilt, or Ormolu, and the base is showing a reddish color that made me believe the metal is either copper or bronze. the jar is 7 1/2 inches tall and 4 3/4 inches across. The metal piece can be removed so you can clean the crystal inside. the crystal is 5 1/4 inches tall. Very good condition with no chips or cracks. Such an unusual piece that can be the center piece of your jar collection!
