I have a vase that I think might be a 9518 in Amethyst. It is certainly the right height (4 inches) but it is not a catalogued colour. I don't have one to compare it with so I was wondering if someone could measure theirs and tell me what the opening size is and also what the width of the vase is (at widest). Possibly the weight as well, I suppose the more comparison points the better.
