The features worth upgrading for

A closer look at the tools included in Pro.

Gem Diagram Gem Designer — building a custom gem cut from scratch with live 3D preview
Pro

Gem Designer

Build a cut from scratch instead of starting from a template. Set angles, distances, and index positions tier by tier, with a live 3D preview that updates as you design. It runs on the same engine behind every pre-loaded gem.

Gem Diagram Cutting Assistant — step-by-step facet cutting sequence with progress tracking
Pro

Cutting Assistant

A tier-by-tier checklist that walks you through the cutting sequence at the machine. Mark each facet done as you go, track progress, and never lose your place mid-stone. Auto-cut takes it further and drives the sequence for you.

Gem Diagram Rough Planner — best-orientation yield search for a piece of rough
Pro

Rough Planner

Find the best orientation to cut a given piece of rough before you touch the dop. Enter the rough's dimensions and material, then let Auto, Tilt-search, or Manual modes estimate yield and finished weight before you commit.

Gem Diagram auto-cut — automated facet-by-facet cutting sequence
Pro

Auto-cut (Cutting Assistant)

Let the Cutting Assistant drive the entire sequence for you, angle by angle and facet by facet, instead of stepping through it manually. Built for studios cutting production volume who want the fastest path from rough to finished stone.

Gem Diagram frosted edges and facets applied to a gem render
Pro

Frosted edges & facets

Add frosted edges and whole-facet frosting to any design, either by hand or by clicking directly on a facet in the 3D view. See exactly how the finished texture will read before it's cut.

Gem Diagram video recording of a gem render in motion
Pro

Record videos of renders

Record an MP4 of your render in motion (turntable, light trace, or a custom path) wherever a record button appears. Built for portfolios, client previews, and presentations that a static screenshot can't carry.

What Pro adds

Your own files

Upload unlimited diagrams, edit them, and save .facet files locally. Import designs from PDF, export as PDF, edit gem color, and use the full materials library.

Design and plan

The Gem Designer to build cuts from scratch, the Rough Planner to find the best orientation and yield, and the Cutting Assistant for a step-by-step sequence at the machine, with auto-cut.

Show your work

Frosted edges and facets, render screenshots, video recording, the Gem Showcase, and Client Preview links that show buyers their stone on a branded page.

Switching from another tool?

Gem Diagram imports designs from the faceting software you already use, no redrawing from scratch.

Gem Diagram vs GemCAD

Open your existing .gem and .asc files and render them in realistic 3D, on any OS, nothing to install.

Gem Diagram vs Gem Cut Studio

Import .gcs designs and add rough-yield planning, a step-by-step cutting assistant, and client preview links.
