# Мinerals
\
Minerals are unique items that can be obtained by collecting gray meteorites during SOLO races. The game features minerals of three colors - purple, red and green.
The minerals obtained are displayed in the player's inventory and can be bought and sold on the marketplace. The seller will be charged a 20% fee when selling minerals on the marketplace.
In the future, a feature will be added to the game that allows combining (merging) minerals and creating gems. By combining three minerals of the same color, with a certain probability players will be able to obtain a gem of the corresponding color.
The gems affect the pilot's parameters. For example, purple gems will increase a pilot's Luck, and red gems will increase their Durability. Green gems will increase a pilot's Income.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.cosmicfomo.com/game-mechanics/characters-and-in-game-items/gems/minerals.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
