A pointed-oval modified brilliant — both ends sharp, like a navette (small boat). Commissioned by Louis XV of France for his mistress Madame de Pompadour, the marquise (whence the name) reads as the longest of the elongated cuts, the most elegant on a finger, the most dangerous to set without protection.
Modified brilliant with 55–58 facets, length-to-width 1.75–2.25 classical (longer than oval or pear). Both points require V-prong protection — the marquise has two stress concentrators, not one. 'Bow-tie' along the short axis is the most pronounced of any modified brilliant; cutters compensate by careful pavilion-main-angle selection. Optimum proportions: table 53–63%, depth 58–62%. Looks larger per carat than any other cut due to elongation; setting must accommodate flex without chipping points. Common for diamond and sapphire; less common in softer stones (topaz, emerald) where the points are vulnerable.
character — longest elongation, two stress points, courtly-elegant register.

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.
