What is legendary gem forager?

As an AI language model, It is not possible for me to share information about "legendary gem forager" since it is an ambiguous term. However, here's some general information about legendary gems in the popular game Diablo III:

Legendary Gems are a type of gem in Diablo III which are initially unrevealed until socketed into an item. Once revealed, they can be upgraded repeatedly to provide bonuses such as increased damage or survivability. There are currently 27 Legendary Gems in the game, each with its own unique effect and the potential for up to 200 ranks of power. Legendary Gems can be obtained from Greater Rift Guardians in Greater Rifts starting at level 1 and can also be upgraded using regular gems and gold. The Legendary Gem Forager is an achievement awarded to the player who levels up a Legendary Gem to rank 50.
