I really like this smallish 8" vase. I think it's alexandrite, but I haven't been able to create a radical colour shift yet. It's oval, with a channel running down both the broader sides. The depressed sections are satinized, by acid I think, but perhaps by sandblasting. The base is flat and polished as expected, but with very little wear. It has a partial ZBS label, which looks to me to be an older, pre Czech Republic one. I haven't been able to find any references to it. Any information, particularly designer, much appreciated.
