Hi Ray. I think the canes are Silesian / Thuringian. These usually turn up in concentric millefiori weights, usually with a spatter cushion. The bases are usually flat, and rather matt - so yours might be original. I think 'Bohemian' is okay as general descriptive term. The glass is often dark, or tinged purple. A word of caution regarding polishing (from bitter experience...): the glass these are made of is very hard, and even the smallest chips often have an invisible crack under them (invisible until you start polishing, that is). And obvious bruises run deep into the weight. So you can end up having to remove quite a bit more glass than you expected - so the weight ends up noticeably smaller.
