Gems are a special mineral crystal in the game used for a variety of uses. They are mined by Miners. There are 6 types of gems: Sapphire, Emerald, Ruby, Diamond , the legendary Blood Diamond and the Dark Diamond.
|Average rate in days||1.74||4||5.79||11.57||289.35||11.57|
|Expected average gem count after 100 days||56||24||16||8||0||8|
After about 100 days, hardcore players may be possible to upgrade all of these tools to their maximum (Diamond tier).
Upgrading tools Edit
Keys for Treasure chests Edit
Socketing a gem into the key gives more chest slots when opened. A gold key (without a gem) opens for one slot, a Sapphire key for two slots, an Emerald key for three and so on.
Stargem Potion Edit
Stargem Potions can also be poured to the gems to turn into Stardust, for 100,000, 200,000, 300,000 and 600,000 respectively. Blood Diamonds cannot be converted. An enchanted version doubles the stardust one receives.
Upgrading mining machinery Edit
Gems can also be used to upgrade mining machines with a chisel, which doubles the ores for certain machines. Drills get double the gold, Crushers get double quartz, Giant Drills get double marble and Excavators get double the promethium.
Special gems Edit
- Because of how rare chests are, it's highly advisable to use at least an Emerald key (3 slots) or a higher tier gem to open a chest. As of now, Emerald keys are the most profitable ones.
- Upgrading machines using the Chisel is an achievement, thus one may consider to use gems to upgrade machinery first, or to upgrade tools depending on set goals.
- In the Doric's Armour quest, the player can give 2,500,000 or 2,000,000 coins instead of 5 Sapphires.
