A square modified-brilliant cut — 49 to 58 facets, sharp pointed corners, brilliant pavilion. The second-most-popular engagement-stone cut after the round brilliant; reads contemporary, edge-to-edge, less wasteful from rough than round. Princess Cut introduced 1979 in modern form (Betzalel Ambar / Israel Itzkowitz) but draws on earlier 1960s 'profile' and 'quadrillion' patents.
Modified square brilliant. Common 4-chevron variant: 57 facets (table, 4 crown bezel, 4 star, 8 upper-girdle, 4 pavilion main, 8 lower-girdle, 4 chevron pairs at 4 levels). Length-to-width 1.00–1.05 for true square; 1.05–1.10 for slight rectangle. Optimum proportions: table 60–75%, depth 65–75%, crown 9–11%, pavilion 65–75%. Sharp corners require V-prong setting to protect. ~80% rough-yield from a stretched octahedron, vs. ~50% for round brilliant — princess is the cutter's economy and the consumer's modern square.
character — modern square brilliance, edge-to-edge fire, sharp corners (chip-prone if unset).

Materials and processes for people who design and make things.
A local-first library of materials, processes, applications, and finishes — equal weight, citable everywhere, so a student can move from "what is this" toward "what's actually buildable here, now, by me." Part of the renato.design ecosystem — sibling of Plenum, Specimen, Ingenue, gesture, graf, and the Renato Rhino plug-ins. Form and matter, inseparable.
Half of teaching materials is teaching how the material is made into the thing. The standard subscription library was always light on that half. The wedge here isn't better samples or a prettier interface — it's treating Process as a peer entity, not a footnote.
