Crushed Topaz drops???

[Predator3088]

Just wanted to know a good place to farm these..... I am a druid who as been farming / lvling off of the Wyverns in CS for about 2 lvls and have seem many gems but not 1 Crushed topaz. (thinking they dont drop it) So i looked it up on wiki and the Haunted Seachest also drop them in CS.... So i started farming them. 1st kill one droped. Now about 1 lvl later i still havent seen any more. Are they just that rare or is there a better camp for them? Any info on this would be much appreciated.

THanks
