The Oldest Thing You'll Ever Own - A scroll-driven diamond deep-time WebGL journey

An open-source, scroll-driven WebGL story published by prodiam. Follow a diamond from deep-Earth formation to a finished ring while a procedural Three.js mesh changes from rough crystal to faceted brilliant. Built with GSAP ScrollTrigger, Lenis, TypeScript and Vite. Explore without a login; source is MIT-licensed. Background films and imagery are AI-generated illustrations, not documentary footage or a scientific simulation.

FacetLab - Polish a rough diamond in your browser, learn the 4Cs

FacetLab is a free, open-source WebGL learning simulator from 4Cs.co.za. Inspect a rough diamond crystal, reveal inclusions, plan the proportions, polish the facets of a brilliant cut, and generate a finished 4Cs scorecard (cut, colour, clarity, carat). It runs entirely in your browser. Educational only: no signup, no pricing, no appraisal. Source open on GitHub.
