Best I can come with is Gesellschaft geschieden, meaning company separated. :huh: Perhaps a company that made parts for another... Pamela should be able to clarify.
One use I found in a glass company, Menzel Gebruder Bavaria, context (courtesy Glass-Study) was "Spezialitäten: Parfümflakons in kristallähnlicher Qualität, Flaschen für den engl. Markt und die Dominions, stets ges. gesch. Neuheiten in Flakons und Flaschen.:
They made pressed and hollow glass including this type of container particularly for the English Speaking market. Run by a Paul Menzel in 1925 but no trace on the web, but there is now a GERHARD MENZEL GLASBEARBEITUNGSWERK GMBH & CO. KG which may or may not be related.
However it is highly speculative to link this company to your piece just on the Ges. Gesch. mark, I mention it as they made this type of item and the context of the mark.
