Why the Tainan atelier cuts its own stones
Byzantium's choice to cut in-house since 1992: the reasoning, how it differs from importing pre-cut stones, and our perspective on the transmission of craft.
The path into the craft
The cutter's trajectory: years of practice, lineage of instruction, family inheritance, and an accounting of stones cut to date.
The cuts we master
Our signature cuts, each accompanied by a photograph of a representative stone.
Credentials and recognition
Professional certifications (GIA, FGA, and others), awards, media features, and teaching record.
Selected works
Three to five pieces of note. Each includes primary image, macro detail, design statement, and the circumstances from which it arose.
The cutting process
A photographic sequence of the stages: rough selection, shaping, polishing, and final inspection.
One or two short-form videos, 30 seconds each, from the workshop.
A stone with particular resonance
The cutter selects a stone that remains memorable, sharing its weight, origin, cutting difficulty, and the story held in its commission.
How I read a stone
The cutter's method: the reasoning and decisions that guide the approach to each rough stone.
