# 33 Collectible Value Formation

Scarcity is an important factor in value formation in collectible markets. Pokémon cards, sports cards, limited-edition figures, artworks, and luxury watches are not priced solely by utility value. Price is formed through a combination of specific series, limited quantities, rare grades, preservation condition, market demand, and community perception.

CryptoStone applies these principles of the collectibles economy to digital gemstones.

| Element                      | Description                                                    |
| ---------------------------- | -------------------------------------------------------------- |
| Total supply by STONX        | Supply differences between Diamond, Ruby, Sapphire, and others |
| Pool difficulty              | Target Power and Difficulty of each pool                       |
| Halving by STONX             | Scarcity Multiplier increase as mined quantity grows           |
| Weight probability           | Larger carats have lower probability                           |
| Color probability            | Higher color grades have lower probability                     |
| Clarity probability          | Higher clarity grades have lower probability                   |
| Cut probability              | Higher cut grades have lower probability                       |
| Low tokenId                  | Collectibility of early-mined gemstones                        |
| Mining time                  | Significance of specific periods and halving stages            |
| On-chain transaction history | Ownership and provenance records                               |

| Element            | Description                                          |

| Refinement history | Refinement generation and supply compression records |

This structure allows users to collect unique digital gemstones mined within a publicly disclosed probability structure, rather than simply purchasing NFT images.

In CryptoStone, rarity is not a marketing phrase. Rarity is formed by supply quantities, probability tables, mining difficulty, and halving structures fixed in contracts.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://doc.cryptostone.org/rarity-and-collection/33_formation_of_collectible_value.md?ask=<question>&goal=<endgoal>
```

`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.
