I built/maintain FacetLab, a free browser-based WebGL simulator for learning the diamond 4Cs through play.
Instead of reading a static explanation of cut, colour, clarity and carat, learners can inspect a rough crystal, choose an orientation, polish facets, and then review a simple 4Cs scorecard.

- Source code: https://github.com/nichesza-max/facetlab
The project is educational only, not appraisal or pricing advice. It is meant as an interactive teaching aid for jewellery beginners, STEM/resource directories, and anyone curious about how visual trade-offs affect a finished stone.
Tech-wise it is a small browser-first WebGL project that does not require signup or a download to try.
