Hi Alan,
Grinding ‘wheels’ are usually cabochon-grinders, to create smooth rounded gems. Only a real craftsman would be able to make facets on such a machine, as it is done
completely freehand. The facets would be concave, just like the facets on this paperweight.
Normal facets, like in gemstones, are made on a rotating flat grinding table, in predefined fixed angles. This results in razor sharp flat facets, like a brilliant-cut used
for diamonds.
...But, i’m happy Harrachov could be a candidate as a maker for this paperweight.
Thanks again for your feedback,
Frank
