Sol Lapidary Foundation collects and digitizes gemstone cutting designs — diagrams, cutting angles, index gear settings, and proportions — and makes them available in a searchable online archive. Each design is preserved with its original authorship and full cutting instructions.
Alongside the archive, we provide browser-based tools for viewing and analyzing designs: spectral ray tracing to evaluate light performance, tilt analysis across refractive indices, and a material library with spectroscopic data for over 150 gemstone species.
Community-contributed designs with full cutting diagrams, searchable by shape, gear, facet count, and proportions. Freely accessible.
Spectroscopic absorption data for 150+ materials, showing how color shifts across daylight, incandescent, fluorescent, and LED sources.
Spectral ray tracing, parametric editing, and tilt performance analysis — in the browser, no installs.
