Crushed Coral (Armor Gem) - Need feedback on drop rates

[Ele]

I have only ever seen 1 Crushed Coral drop in the entire time of beta testing.

[Mon Mar 24 11:39:43 2014] Frosticube has been slain by Kindadar!
[Mon Mar 24 11:39:43 2014] You gain party experience!!
[Mon Mar 24 11:40:03 2014] You are too far away to loot that corpse.
[Mon Mar 24 11:40:11 2014] --You have looted a Crushed Coral.--

Has anyone else had luck with these dropping? I'm wondering if it might be missing from the loot tables of the armor gem dropping NPCs.
