Wheel Spin Quest

Wheel Spin Quest is a faceting bench for the decisions you make before the lap ever touches the stone. Pick a material, set the crown and pavilion, and the stone is traced in cross-section: rays enter through the table 📋, refract, and either return to the eye through the crown or escape out of the pavilion as a window. Every material carries its own refractive index, so the critical angle you have to stay above is computed rather than remembered.

For the cutter at the bench: load a design, set the pavilion on a detented dial, and read the verdict as you turn it — window, optimal, or nailhead — beside a light-return gauge and the returned and leaked rays drawn exactly as they fall.

For working out a cut: move through twelve faceting designs with their facet tiers, index positions recalculated for a 96, 80 or 64 tooth gear, and a suitability reading for every material on your bench. Save 💾 your own angles as a design and it takes its place in the tray.

For a material you have not cut before: open the formulary — sixteen stones with refractive index, critical angle, specific gravity, hardness and dispersion — and see 👀 light return charted against pavilion angle across that stone's own window. Tie-in searches the new ✨ material's returning band in 0.1 degree steps.

For the rough still on the paper: keep a parcel with dimensions, stage and planned design, photograph each stone and drag ✋ a reticle across it to sample the body colour, and read finished weight and yield before you commit to anything.

Wheel Spin Quest helps you evaluate every cut with precise optical data, while Wheel Spin Quest keeps your designs, materials, and rough organized entirely offline 📴.
