If you reload for malachite veins and/or FoV quests, and limit the number of level 10 and healing aura enchantments you use, there are plenty of malachite gems to be had (including two I used for healing auras and another two for the blind philosopher, I collected 69 total).
Welcome to the forum.
i know this is a late reply but thanks for the welcome,
69 total!!??!!???
i hope to get nearly as much in my 2nd playthrough

can't decide whether to play a mage or an archer next...
