About This Game

About This Game

Find rough stones. Cut them. Watch how they react to light. Collect them. Put them on display.

RigidGems Museum is a collection game where you travel around the world in search of rough stones, cut them into gemstones, and build your own digital gemstone museum.

The game features 59 minerals and more than 500 gemstone cuts.
Many designs are included with permission from real-world cut designers and rights holders. Even when using the same mineral, different cuts can dramatically change the way a gemstone reflects light and displays color, transparency, and brilliance.

At the heart of the game is another important element: real-time gemstone rendering technology that has been in development since 2009.

Real-Time Gemstone Rendering Since 2009

Development of the gemstone rendering technology used in RigidGems Museum began in 2009.

At the time, dedicated RT cores and DirectX Raytracing did not yet exist.

To render repeated reflection and refraction inside transparent objects at interactive frame rates, years of development went into creating proprietary rendering techniques and optimizations.

FerioWorks has never focused simply on relying on increasingly powerful hardware.

The goal has been to achieve complex real-time light transport within limited computational resources while keeping the result fully interactive.

RigidGems Museum turns that technology into something you can directly interact with, using a wide range of minerals and gemstone cuts.

The engine calculates effects such as internal reflection, refraction, dispersion, and absorption in real time, producing different visual characteristics depending on the mineral, color, transparency, shape, and cut.

From Rough Stone to Gemstone

Travel to locations around the world, search for rough stones, and choose how to cut the stones you find.

Even with the same mineral, the finished gemstone can look dramatically different depending on the cut—from familiar forms such as round, oval, and cushion cuts to designer cuts with complex facet structures.

Which mineral should you combine with which cut?

Watching those combinations react to light in real time is one of the central experiences of RigidGems Museum.

More Than 500 Gemstone Cuts

RigidGems Museum includes more than 500 gemstone cuts.

Many of them are designs included with formal permission from real-world cut designers and rights holders.

The goal is not simply to finish processing a gemstone. You can experiment with different cuts, compare them, discover combinations you like, and preserve them as part of your collection.

Create Your Own Cuts with GemCutDesigner

You are not limited to the cuts already included in the game.

With GemCutDesigner, you can create original gemstone cuts by defining their overall shape and structure.

The system adjusts the geometry, allowing relatively simple input to produce more complex cut designs without requiring specialist knowledge of professional gemstone cutting.

Designs created with GemCutDesigner can be used directly on gemstones in the game.

GemCutDesigner does not generate cuts by learning from existing cut designs. Its shapes are constructed through geometric generation and geometry-processing methods.

Minerals That Change with the Light

Not every mineral interacts with light in the same way.

Minerals such as ammolite can display dramatic changes in color depending on viewing angle and the direction of light.

Minerals with optical behavior different from conventional transparent gemstones use their own real-time visual treatments.

Change the mineral.

Change the cut.

Change the viewing angle.

Change the light.

The same gemstone can reveal an entirely different appearance.

Fantastical Inclusions

Some rough stones may contain special inclusions.

Fantastical inclusions inspired by flowers, planets, galaxies, and other motifs are not intended to reproduce features used in real-world gemological identification. They are discovery and collection elements unique to the game.

Even two stones with the same mineral and the same cut can feel very different depending on what appears inside them.

Searching for unusual stones to add to your personal collection is another part of the experience.

Build Your Own Gemstone Museum

Finished gemstones can be placed freely throughout your galleries.

Arrange your favorite stones.

Compare the same mineral with different cuts.

Create exhibitions based on color or shape.

Build a gallery dedicated to unusual specimens.

Use glass display cases and other exhibition items to create your own digital gemstone museum.

A Collection Experience Without Competition

RigidGems Museum does not require you to compete with other players or rush toward a time limit.

Search for minerals, experiment with cuts, collect gemstones you like, observe them under different lighting conditions, and display them however you want.

Discovery, collection, observation, and exhibition—at your own pace—are at the core of the game.

RigidGems Museum is not intended to reproduce professional gemstone grading or serve as a full gemology simulator.

It is an interactive experience combining real-time gemstone rendering with mining, cutting, collecting, and exhibition-focused gameplay.

Proprietary Rendering Engine

RigidGems Museum runs on a proprietary real-time rendering engine developed specifically for the project.

The game is not a DXR-only title.

The engine includes its own real-time ray tracing implementation, allowing the game to run even on GPUs without dedicated RT cores.

On compatible hardware, DXR rendering can also be selected.

More powerful GPUs can provide higher resolutions and higher frame rates, but the fundamental gemstone rendering system is not designed to depend exclusively on a particular generation of GPU hardware.

Real-Time RT Benchmark

In addition to the main game, RigidGems Museum includes a benchmark mode for testing real-time ray tracing performance.

During normal gameplay, you can also enable a technical information display showing data such as:

• GPU

• Resolution

• FPS

• trace/sec

• rays/pixel

This allows you to observe how rendering load changes across different minerals, cuts, viewpoints, and scenes rather than being limited to a fixed benchmark sequence.

These features are intended as additional tools for hardware enthusiasts and players interested in real-time graphics. They are not required for normal gameplay.

Streaming and Video Policy

You are free to livestream and upload videos featuring gameplay from RigidGems Museum.

Content creators may freely:

• Livestream gameplay

• Upload gameplay videos

• Monetize videos and livestreams

This applies to platforms such as YouTube, Twitch, TikTok, and other video and streaming services.

No prior contact with the developer or special permission is required.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Generative AI tools may be used in the creation of some artwork, background music, text, localization, and other pre-generated content included in the game. All AI-generated or AI-assisted content is reviewed and selected by the developer before being included in the game. No live-generated AI is used during gameplay.
