Traditional Hanaporuwa bow-lathe vs modern facet machines in Beruwala lapidary?
3 Answers from travellers
The traditional bow-lathe (hanaporuwa) provides tactile feedback that digital faceting heads cannot replicate. The cutter holds the wooden dop stick by hand and drives the lead or copper lap wheel with an animal-sinew or nylon bow. This hand-guided technique allows the master cutter to follow irregular natural color bands in corundum, angling facets dynamically to preserve carat weight and orient deep blue color patches directly into the culet. While modern calibrated cutting demands mechanical faceting machines for angle symmetry, the bow-lathe maximizes finished weight recovery from costly rough.
European and American buyers frequently discount native-cut stones for "windows" and uneven pavilions, necessitating re-cutting on modern digital machines upon return.
Lead polishing laps coated with diamond paste create facet luster without thermal rounding, preserving sharp junctions between pavilion facets.
