This is a Bohemian art glass perfume bottle (cologne or scent) made from a mold in a glass that is called malachite or jade, in emulation of the stones. The maker is Schlevogt. The mold series is called Ingrid. The perfume bottle is from the original mold and not a later production. The date is circa 1935.
The mold is amazing. The sides are polished smooth to emulate the stone. The corners, top and bottom have large roses or flowers in the glass, and they are finished off with a lot of hand work so that no seams from the mold can be seen. The four bottom feet are also polished flat, and the bottom depicts more flowers.
The perfume bottle is 5 ¼" high and 3 ¼" wide.
The bottom of the stopper has been shortened by a glass repair professional. The bottom of the bottle shows some fine lines, but they don't appear to be cracks, just part of the mold work. There are a few tiny spots of roughness that can be felt with the fingertips, but no nicks show under a magnifying glass. There are no chips. The inside of the mouth has indentations that are not chips, but how the glass was made.
