No nothing like Chrysoprase.
Could be BrĂ¼der Rachmann, Haida. (1874-90 in Germany, 1890-c1945 in Haida. Offices in Berlin and Vienna. Gold medals from various world fairs.
Ivo thinks they are a glass refinery (decorator/finisher) but the only online ref I could find was a that they had both a metal works and a glass-works in Haida. They produced a large number of Atomizers. But apart from a catalogue I have can find very little else. They probably made to contract as after 2 years looking I have found nothing that can be attributed to them, nor any atomizers that are exact matches to some 600 shown.
Also toilet sets, and other household glass often combing metal and glass.
Is there any type of mark on the metalwork at all?
