Hi. I believe that these early Chinese paperweights were made in the 1900 to 1930 period. I think the 'five lobe' rather than 'six lobe' may represent a different factory in China, rather than a different country of origin. The profile of these pieces and the glass are quite unlike any known 'Bohemian'* pieces, and quite like later Chinese ones. That is not proof, I realise, but I think it is a strong indicator.
* Bohemian. This word seems to get used very loosely (especially in the US) to mean anything from Central / Northern Europe that is not French, Italian or Belgian. So items from Poland, Czechoslovakia, Thuringia, Austria and elsewhere can all end up being called 'Bohemian'.
