Vintage Art Deco Czech Neiger Brothers, Max Neiger faux turquoise glass cabochon and silver tone dress clip

Fabulous vintage Art Deco silver tone and turquoise blue glass cabochon floral dress clip by Max Neiger. This is such a delicate and detailed piece with many features and techniques of manufacture that suggest it is a Neiger piece.

There is aa word stamped into the metal on the reverse, just underneath the clip hinge. I can't make it out, but it would most likely say 'Czechoslovakia' or 'Czechoslovak' as with some other pieces like this. It is in very good vintage condition - minor age-related wear to the back of the clip as pictured, but the front is stunning.
