Custom Zirconia & Corundum

CZ is what we use for silver samples and volume work. Calibrated to 0.1 mm so it drops into a standard setting without reaming.

We do not keep stock. Each order is drawn around your center stone and ring size, quoted in writing with metal weight and stone specification, then cast in our own workshop in Wuzhou. If you already own a stone, send us its millimeter size and a photograph — that is enough for a first CAD.
