Antique 1930's RARE Czech Black Onyx Glass with Malachite Art Deco Perfume Bottle Art Noveau

Antique 1930‘s RARE Czech Black Onyx Glass with Malachite Art Deco Perfume Bottle. Insanely gorgeous collectors piece with brass details and a huge malachite stone in the middle. Has dauber. However that piece has been encrusted with whatever perfume was in it. I don‘t want to try force it open. Polished it as much as I can, but this is an antique piece and I don‘t want to damage it. There seems to be some perfume left. Just shy of 3.5"" long, about 2.5"" long.
