Cutting order is the sequence in which a faceter cuts the tiers of a design. Each new tier is cut to meet the tiers before it.
In more detail
The design gives the order, because a tier cut too early has nothing to meet. A typical round starts with the pavilion, then turns over for the crown.
How we measure it
Our tier table lists every tier in cutting order.

- Tier: A tier is a set of facets cut at the same angle, at several index positions around the stone. A faceting design lists its tiers in cutting order.
- Tier table: A tier table lists the angle, index positions and cutting order of every tier in a faceting design. Ours comes as a .csv file that opens in any spreadsheet.
- Meetpoint: A meetpoint is a point where the corners of neighboring facets meet. Faceters cut each tier to its meetpoints so that the facet pattern closes exactly.
- Faceting machine: A faceting machine cuts and polishes a stone one facet at a time. It holds the stone on a dop at a set angle against a flat, spinning lap.
