Who it's for

Built for the people who cut and trade stones

Diamond cutters and planners, manufacturers, and dealers working with fancy‑colored and white diamonds — anyone who wants to see a stone's best before committing to the cut.

See & improve color

Get the most color from every stone

Working for better color, or a better make? DiamCut Pro assists either way — judge every change the moment you make it, on screen, before a wheel ever touches the stone.

◆ See where the stone shows its color strong — and where it washes out.
◆ Compare a reworked design against the original, side by side.
◆ A before / after slider to judge the gain at a glance.
◆ View the stone under a choice of lighting environments.
◆ Match the on‑screen stone to a reference photo of the real one.
◆ A large palette of body colors, plus your own custom shades.

Edit every facet

Direct, hands‑on control of the cut

Click a facet on the 3D model and shape it exactly the way you want. Symmetry, new facets, and a live preview keep you fast and in control.

◆ Click any facet and adjust its angle, tilt, or position.
◆ Mirror and fold edits across the stone's symmetry automatically.
◆ Add new facets, or complete a facet to a chosen point.
◆ Delete or hide facets, with full undo / redo.
◆ Live preview — the render updates as you work.
◆ See the original stone over your recut to track exactly what changed.
◆ A running weight tracker so you see the carat impact as you cut.

Shape & girdle

Refine the outline and clean the girdle

Lay a target outline over the stone and trim to it, then even out and center the girdle — the shaping work that defines a clean, attractive cut.

◆ Reference outlines — oval, cushion, pear, heart, marquise, radiant — fitted to the stone.
◆ Trim the girdle back to the chosen outline in one step.
◆ Even out an asymmetric or bulging girdle; straighten and center it.
◆ Selective girdle thickening by region.
◆ On‑screen measurement cross and grid for length and width.

Bulging outline detection — **Bulging outline** — spot and even out a girdle that bulges past the target shape

**Cleft creation** Paid service — add a clean cleft to hearts and fancy shapes

Photoreal renders, 3D & live web view

See the finished stone before it's cut

Produce striking face‑up and full 3D renders, spin them as video, and share a live, interactive 360° view with a single link — nothing for the viewer to install.

◆ Face‑up and full 3D photoreal renders.
◆ Studio and environment lighting presets.
◆ Fire / dispersion for spectral sparkle.
◆ Animation export — turntable, rock, figure‑8, profile spin — as MP4 or GIF.
◆ A live, spinnable 360° view of your stone, shareable by a single link.
◆ Send us your file and we render the 360° view and return a link to share — for a small fee. Paid service

View a live 360° stone

Photoreal photo rendering runs best on a computer with a dedicated graphics card (GPU); high‑resolution renders and animation are faster on stronger systems.
