Gems
From PotionEmpire Wiki
The gems are a set of 12 ingredients that can be found in various ecosystems, and are divided into 2 groups: basic and special. All the gems are required to complete the Gem Collection Quest. There is also another gem in game, the Emerald Gem, but it's not part of the collection since it's not findable in nature but can only be created by refining Raw Emerald.
