Antique Glass Powder Box: Diamond Point Blue Slag Amethyst Lid

This is an antique glass powder or trinket jar. The base is a powder blue slag with a diamond point pattern. The lid is dark amethyst lid with the diamond points in a guilloche pattern. There is a little roughage you can feel when you take off the lid and feel the inside of the mouth, but overall it is in fine condition with no cracks or chips. It is likely from the early 20th century.
