# Pickaxes
**Pickaxes** are the tools players need to have in order to mine for gemstones. They differ in correlation with two factors, ***mining power and durability.*** Each factor plays a major role in impacting the gameplay.
**Mining power** refers to the power of pickaxes, the greater the mining power the easier the pickaxe is able to mine more valuable gems while preserving its durability.
**Durability** is the pickaxe's stamina, it prolongs a pickaxe's mining time. the higher the durability bar the longer a player can mine. However, it is always correlated with the mining power thus being heavily influenced by it and the way players use it.
Pickaxes come in 5 different rarities, "***common, uncommon, rare, epic, mythic (JACKHAMMER)***".
    
Each rarity has 2 stats lines.
| Pickaxe | Durability | Mining Power (%) |
|---|
| Common | 100 | 10 |
| Uncommon | 200 | 20 |
| Rare | 500 | 30 |
| Epic | 750 | 50 |
| Mythic (JACKHAMMER) | 1000 | 100 |
{% hint style="warning" %}
Using a lower-grade pickaxe on a higher-grade Gem mine will consume your pickaxe's durability at a much faster rate.
{% endhint %}
{% hint style="info" %}
In order to calculate how many times a particular gem mine can be farmed, the formula below can help you :
***x = Pickaxe's Durability / Gem mine's*** [***recommended Mining Power***](/cryptogem-whitepaper/nfts/gem-mines.md#recommended-mining-power)
***For Example :***
You will be able to mine the **Quartz** gem mine ***10 times*** with a ***common*** pickaxe.
**x = 100 / 10 = 10 times**
You will be able to mine the **Diamond** gem mine ***1 time*** with a ***common*** pickaxe.
**x = 100 / 100 = 1 time**
{% endhint %}
{% hint style="info" %}
***Durability requires 3 hours to be fully charged when it is fully drained.***
{% endhint %}
