A real faceting workbench: slice a 3D gem with true index-gear geometry, browse a deep library of designs, follow step-by-step cutting guides, and render the result with a live raytracer. No install, no download.
Pluto merges the design table, the cutting guide and the render viewer into a single studio — the same convex plane-clipping engine drives all three.
Start from a rough stone and cut your own faceting design with real index-gear geometry, symmetry and meetpoint chaining. Press Cut and the 3D gem is actually sliced.
Create original cutsBrowse and filter a curated library of designs from renowned faceters, then render each one in any of 60+ gem materials to preview fire, brilliance and colour.
Explore the libraryFollow a guided, step-by-step cutting sequence — every tier, angle and index position spelled out — so you can take a design from the screen to the lap with confidence.
Step-by-step guideA genuine in-browser raytracer, plus the reference tools a faceter actually reaches for — no spreadsheets, no side apps.
Start from a rough stone and build an original faceting design with real index-gear geometry, symmetry and meetpoint chaining. Press Cut and the 3D gem is actually sliced — then put it under Pluto's optical analysers to measure light and fire long before you ever touch a lap.
Analyse Light fires tens of thousands of rays across 17 viewing directions and reports how much light your design returns to the eye, plus where the rest escapes.
Analyse Fire sends dispersed red-and-blue rays through the stone to quantify fire — the rainbow sparkle a design coaxes out of a material's dispersion.
Cut mode turns any design into a step-by-step cutting sequence and shows the 3D gem taking shape facet by facet as you work down the list.
Follow the sequence on screen and watch the rough resolve into a finished cut. The next facet is highlighted live, so there's no guesswork between the design table and the lap.
Classic brilliants, step cuts, barions, hearts, fantasy cuts and originals — every one a real, cuttable meetpoint design, and the collection keeps growing.
In Roman myth, Pluto ruled the underworld — and with it every precious thing buried beneath the earth: the metals and gemstones hidden in the dark. The god of gems, of riches below.
Unearthed is the joy of bringing them up into the light — a studio for exploring, cutting and discovering gems.
No paywall to look around. Pro adds an account — the maker's tools, the full library, and your designs saved to the cloud.
Open the studio and start exploring — no download, no sign-up required to begin.
