Cutting files and 3D models for gemstones, built from one measured geometry. Each of a stone's seven file types describes the same stone, never more than a hair's width apart.
One geometry, two ways to use it. Cutting files take a design to the faceting machine. 3D files take the same stone into CAD, rendering and jewellery manufacture. Both are built from the same geometry, so the angles you cut are the angles you render.
Everything a cutter needs to put the design on the machine, with every angle and index taken straight from the geometry.
Exact faceted models with flat facets and clean edges, ready for settings, renders and production.
From the modern round brilliant back to the cuts of the seventeenth century. Where a cut was rebuilt from a historical source, the product page names the source. See every cut.
Round brilliants cut to the 1919 proportions, in order of subdivision.
The evolution of the brilliant, from the single cut to the 1919 knife-edge round.
A file is only as good as its geometry. Ours is constructed from angles and indices, never scanned, sculpted or guessed, and then checked the way light would check it.
Every stone is constructed exactly: flat facets meeting at clean edges and points. The meshes are exported from that construction, not the other way round.
The cutting file, the tier table and the 3D model all come from the same geometry. There is no second drawing to drift out of step with the first.
Each cut is traced through the ray-tracing engine behind Brilliani Labs, so its light return is a measured figure you can reproduce, not an adjective.
In preparation
How light moves through a stone, and how to design a cut that sends it back to the eye. Taught with the same tools and the same geometry as the files, so every idea can be seen working rather than taken on trust.
We will send you one email when enrolment opens, and nothing else.
Planned outline. It may change before the course opens.
The diamond simulator and its companions were built at Brilliani Labs, and they will move to Digital Gemology. Until then, they live at brillianilabs.com.
A real-time ray-traced diamond you can grade, turn and compare. For members.
