# 13. 採掘周期

各ストーンは、それぞれ異なる基本マイニング周期を持つ。

| STONX      | Base Mining Interval |
| ---------- | -------------------: |
| Garnet     |          170,000 sec |
| Amethyst   |          160,000 sec |
| Aquamarine |          150,000 sec |
| Diamond    |          220,000 sec |
| Emerald    |          210,000 sec |
| Pearl      |          180,000 sec |
| Ruby       |          200,000 sec |
| Spinel     |          140,000 sec |
| Sapphire   |          190,000 sec |
| Opal       |          130,000 sec |
| Topaz      |          120,000 sec |
| Zircon     |          110,000 sec |

基本マイニング周期が長いほど、同じマイニングパワーで採掘することが難しい。したがって、ストーン別希少性は次の2つの要素によって一次的に形成される。

| 要素                   | 説明                        |
| -------------------- | ------------------------- |
| Max Supply           | 当該ストーンの総発行可能数量            |
| Base Mining Interval | 基準マイニング単位で1個を採掘するために必要な時間 |

たとえばDiamondは供給量が最も少なく、基本マイニング周期も最も長い。これは、DiamondがCryptoStoneエコシステム内で最も高い構造的希少性を持つように設計されたものである。

# Agent Instructions
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/crypto-stone/crypto-stone-wp-jp/mainingushisutemu/13maininguno.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.
