Why single-material matters here
A factory running amber, agate, wood and resin through the same cells optimises for none of them. Amber punishes that more than most materials: it is soft, it is heat-sensitive, and it shows every shortcut in the polish. The parameters that make agate efficient will cook amber.
Specialising means the tooling geometry, feed rates, coolant strategy, dust extraction and inspection lighting are all set for one material. It also means our operators have handled tens of thousands of amber beads and can see a half-shade drift that a generalist would pass.
