Sorry but I do not want you to go without an answer. I can't tell much from your picture. It looks like a modern piece from the picture but I know that clear glass is very hard to photograph. When I sold on Ebay I used to use a black cloth backdrop and 500 watts of diffused halogen to photograph with fast film and it was still unclear at times. To me the glass looks thick and the pressed pattern looks lacking in definition. Old pressed glass had many characteristics. Most pattern glass was utilitarian and was not crystal clear but had a sharp definition of the pattern. Sandwich and other flint glass was very clear and even today looks like it could be new. One tap on most pieces, but not all, produces a bell like ring. Cut glass imitators made pressed glass to look like cut glass with the clarity and feel but lacking in the sharp feel of the cutting. Some were pressed and then cut. Crystal producers all over the world have been pressing, etching and cutting for hundreds of years and still do today. It was only a couple of weeks ago that my wife bought a compote from a thrift store that I would have sworn was American pressed glass except for and foil label from the 50's that said Germany. It is an area that is hard to give an opinion on without a hands on inspection. I have been doing it for a long time and still need to extensively research odd pieces. Pressed pattern glass is easy if it is a pattern like thistle or tulip but classics like hob star or daisy and button, like your appears to be, are very hard to determine.
