Vintage vase of green glass with serrated edge and unusual shape

Nice, uniquely shaped green glass vase. The serrated edge at the top, many other wavy movements. Unfortunately not a brand, but given the color and style this looks like a 1950s or 60s vase. It has a small scratch at the top of the glass, in the middle of the photo.

Size: 4.9inch x 7.1inch / 12.5cm x 18cmt.
