Dunfire Diamonds are a Dwarf's Best Friend

Captain E.L. Irontoe has informed me that the Grungetalon goblins have begun to decipher the worth of some hidden gems embedded into the walls of Brell's March. My mission is to recover as many of the gems as I can carry in a and return to West Fort Irontoe.
==Steps==
# Run to the West Fort Irontoe Arms House and inspect the chest to get a to carry the recovered gems.
# Enter Brell's March in Kaladim to recover various gems that conceal arcane purposes and to find and destroy the goblin's source of gem analyzing.
#Harvest 10 Dunfire diamonds (ground spawn) (requires a mining skill of 100+)in Brell's March area behind Bloodforge Gate.
# Slay at least 6 Grungetalon gemmasters to collect some Brell baubles (auto update, un-common drop). Gemmaster's are in groups of 3 level 31 Heroic (gemmaster is no arrow, grouped with two gemcutters two down arrows) in the Brell's March area.
# Slay at least 8 Living chests to collect some Underfoot stars (auto update). Living chests are 33vvv paired with Grungetalon porters 33 Heroic encounter. (very-uncommon drop, and there are never more than four at once. They're also located right in the entrance, so you'll be competing with everyone who comes in, even if they're not on the quest. Respawn time is at least five minutes)
#Seek and destroy the thing that is revealing the magic in the gems.
#*Find the Gem Analyzer in Brell's March - it will be close to one of the trampler's either left or right of the gate. 
#*Examine to receive a subquest, Gem Analyzer.
#*Once the subquest is complete, return and right click the analyzer, selecting "Disassemble the Gem Analyzer".
#Return to Captain E.L. Irontoe
