I have seen this design by Iwatsu executed in clear glass and was pretty excited to find this one in neodymium.
It's an unusual thing for Iwatsu - they didn't often make a completely moulded form like this in their larger works.
It's very Sklo Union in style, and I'm sure with the flat ground base that they have been misidentified many times. Having said that, I have only ever seen this design for sale in Japan, so I don't think it was an export model.
