This vase is deeply cut and measures 23cm in height. the dia. at the top measures 6.8cm dia. and the base stand 6.8cm dia. Directly on the top rim of the vase within the outer dia. and the inner dia. are machined tapered. I have not seen this before. directly underneath the base are cut markings in sets of 3 and equally spaced around the base, a total of 6 sets. Hopefully this will be seen in the attached pics. The vase is approx. 0.7cm thick. Can anyone identify this beautiful vase, with possible originator and age. Kind Regards
