Hello,
I got this 'crystal ball' today and am absolutely fascinated with it... It's 7cm tall and weighs 690g. The top is irridized (forgive me if that's not the proper term for the 'burned' or 'oily' effect

) and the body is the clearest glass I have ever seen. It's a shame my photos don't do it justice.
It also has a wonderful magnifying property, as you can see in the last picture.
It was sold to me as Czech though I haven't been able to find any confirmation. There is very little wear to the base, so I wouldn't be surprised if it's new (the seller was convinced it was 1920s/30s :usd:). I'd appreciate some help... Thank you for looking.
