# 26 Weight 속성

무게는 모든 스톤이 공통적으로 CT, 즉 캐럿 단위를 사용한다. 그러나 각 보석의 무게 값은 랜덤으로 생성된다.

* Minimum Weight = 0.10 CT
* Maximum Weight = 200.00 CT
* Storage Unit = 0.01 CT

스마트컨트랙트에서는 소수점을 직접 저장하지 않고, 0.01 CT 단위의 정수로 저장한다.

| 표시 무게     | 컨트랙트 저장값 |
| --------- | -------- |
| 0.10 CT   | 10       |
| 1.25 CT   | 125      |
| 10.50 CT  | 1050     |
| 200.00 CT | 20000    |

무게는 균등 확률로 생성되지 않는다. 현실 보석에서 큰 캐럿일수록 희귀한 것처럼, CryptoStone에서도 큰 무게일수록 낮은 확률로 생성된다.

| Weight Range       | Probability | Score |
| ------------------ | ----------- | ----: |
| 0.10 \~ 1.99 CT    | 75.00%      |     0 |
| 2.00 \~ 4.99 CT    | 15.00%      |     5 |
| 5.00 \~ 9.99 CT    | 6.00%       |    10 |
| 10.00 \~ 49.99 CT  | 3.50%       |    16 |
| 50.00 \~ 200.00 CT | 0.50%       |    20 |

위 표의 Score는 최종 Gem NFT 등급을 직접 확정하는 값이 아니라, Rarity Score와 Probability Rarity Index를 계산하기 위한 Weight 속성 점수다. 최종 Gem NFT 등급은 Pool Supply Score, Weight, Color, Clarity, Cut의 조합을 종합하여 Common, Rare, Epic, Legendary, Genesis의 5개 등급으로 산정한다.

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-kr/gem-attributes/26_weight_-_.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.
