I really like neodymium glass - it is one of my favorites.
It changes color depending the type and spectrum of the light source. Normally it will appear reddish-purple under daylight, yellowish under incandescent light, blue under white fluorescent lighting, or greenish under trichromatic lighting. It can also appear clear depending on the angles.
Moser's "Alexandrite" glass started its use in decorative glass in the late 1920s and continues to today. Starting in the 193os some other companies began to copy it and included Heisey, Fostoria, Cambridge, Steuben, Lalique, some Murano companies, and Tiffin. Modern production is made by various glassmakers in the Czech Republic, the United States, and China. By the style of yours I agree completely that it appears to be later production.
I can understand your thought that this is similar to art deco in design, but I am not sure I would label it that. It is a pleasing faceted design.
