New3D files and variations in words

Photoreal jewelry renders straight from your CAD

Upload a CAD screenshot or a 3D file (.3dm, .obj or .glb), pick the angle, metal and stones, and get a render you can send to your client. Want to show them something new? Describe it and HeyGema™ makes a variation.

3D model

Two ways to start

Start from a screenshot, or from the 3D file itself

Same steps, same materials, same quality. Use whichever you have on hand.

Image

Upload a screenshot

Any shaded view from Rhino, Matrix, MatrixGold or your CAD software of choice. The render keeps the angle you captured.

Pick Front, Side, Top, ¾ or Back in one tap, or turn the model freely. HeyGema™ sorts every part into metal and stones for you.

.3dm, .obj, .glb

We don't save your 3D files. They stay on your computer.

How it works

From CAD to client-ready in four steps

Try it now
  1. 01

    Add your design

    Drop in a screenshot of your CAD or a 3D file (.3dm, .obj or .glb).

  2. 02

    Choose your angle

    With a 3D file, tap Front, Side, Top, ¾ or Back, or turn the model yourself. Screenshots keep the angle you captured.

  3. 03

    Pick metal and stones

    Yellow, white or rose gold, then the centre stone and side stones. Add details like milgrain or a brushed finish.

  4. 04

    Render and explore

Variations in words

One design, every idea your client wants to see.

Describe a variation, like a different centre stone or a brushed finish, and HeyGema™ makes a new version of your render. Your original stays as it is, so you can show every option.

Make the diamond band rose gold and keep the rest yellow gold
  • Try a different stone, a brushed finish or a closer crop
  • Every version is saved, so you can show them side by side
  • Each variation uses 1 render

HeyGema™ is a render tool for jewelers. Upload a CAD screenshot or a 3D file (.3dm, .obj or .glb), choose the angle, metal and stones, and get a photorealistic render you can send to clients.
Images of your CAD (PNG, JPG, WebP and other common formats) and 3D files: Rhino .3dm, .obj and .glb. For other 3D formats, such as STL, upload a screenshot instead.
Yes. HeyGema™ is free forever and doesn't ask for a credit card. If you render more, Starter gives you 25 renders a month and Pro 65, both with no daily limit.
Yes. Describe the variation you want, for example “try a brushed finish” or “show it in rose gold”, and HeyGema™ makes a new version. Your original is kept, every version is saved, and each one uses 1 render.
Renders are photorealistic images of your design, made to show clients and get their approval. Check proportions and stone sizes against your CAD before production.
No. HeyGema™ runs in your browser on desktop and on your phone. You sign in with Google or with your email.
If it's a .3dm file, it was probably saved without render meshes. In Rhino, set a viewport to Shaded, then use Save (not Save Small) and upload the file again.
You do. We only use your uploads to create your renders.
