Earn Fast Honor in TBC Anniversary
While you can go to the Auction House and purchase gems or have a gem cut by a Jewelcrafter, there are actually some cheap alternative ways to earn gems through PvP activities.
Mark of Thrallmar/Honor Hold (Hellfire Peninsula)
In Hellfire Peninsula, you can acquire several different types of gems by spending Mark of Thrallmar (Horde) and Mark of Honor Hold (Alliance).
The main way to earn these is by completing the daily quest Hellfire Fortifications (there's a Horde and Alliance version).
Halaa Battle Tokens (Nagrand)
In Nagrand, you can earn Halaa Research Token and Halaa Battle Token by completing objectives related to the PvP zone, Halaa. However, for the gem, Sublime Mystic Dawnstone, you need 100 Halaa Battle Tokens, which you can earn by killing enemy players in Halaa when you're PvP flagged.
Additionally, there is a limited-supply gem that can be purchased from either Coreiel (Horde) or Aldraan (Alliance) if your faction currently controls Halaa:
Honor Points
Using Honor Points, there are six different gems you can purchase. Four of them cost 2,855 Honor Points each (Red and Yellow gems), while the other two (Orange gems) cost 3,525 Honor Points.
These can be purchased from Master Sergeant Biggins (Alliance) and Brave Stonehide (Horde).
