Gems are rare items that can be obtained with luck from the game. There are 5 types of gems: Sapphire, Emerald, Ruby, Diamond and Blood Diamond.


Unlike most ores and materials, the gem drop rate is unaffected by anything in the game.

Uses[edit | edit source]

Upgrading Tools[edit | edit source]

The way of upgrading tools is in a defined order, based on its rarity, from Sapphire to Diamond. A low level gem must be used before using higher level gems.

Selling[edit | edit source]

Gems can be sold either to the NPC shop for 1/10 of the rarity (e.g. sapphire is 1/100,000 chance so it sells for 10,000) or the players market where if one decides to sell, one should always sell to the players market as you are guaranteed to achieve higher revenue when compared to the NPC shop.

Tips[edit | edit source]

  • You should always keep your gems and use them for upgrades. There are a few exceptions that are situation dependent, so in case you aren't sure what the right thing to do is just ask the chat.
