The trouble is that many auctioneers and dealers ought to have an MCD after their name. MCD = Master of Creative Description. They don't know so they go for a relatively expensive descriptor that for most people is impossible to refute. Then there is the problem of the Whitefriars of this life who produce such an enormous range of items it is almost impossible to remember them.
I suggested Holmegaard because of the blueish tinge to the glass and the rolled rim reminded me of the Umanak range.
One of the problem's I am having in assisting you is the distortion of the shapes from taking the photos too close, On shot makes the sides seem quite straight, another that make it have narrowing from top to bottom. The best way is to provide four photos - #1 a general shot of it on a white clot, #2 a profile shot from the side taken far enough back that it does not distort, #3 a very clear shot of just the base square on, and #4 a similar photo of just the rim from square on. One way to see why this is a problem is to use your mobile phone. Turn the camera to your face and then put your finger between the camera and your face. It will look enormously large compared to what you know is its true size. As you move it away to level with your face the distortion disappears. The hassle with your photos is the distortion of the nearest parts of the vase - hence my suggestion to take them further back. When you crop and resize them for the GMB they will stay proportionate.
Giving measurements quote both height and diameters (if there are differing diameters tell us what each is).
