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 62 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.
Classic brilliants, step cuts, barions, hearts, fantasy cuts and originals — every one a real, cuttable meetpoint design, and the collection keeps growing.
The name
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.
