@Crazy Horse - Only the 4-3 CG give Pure Darkmoon Stones. So, only on a next playthrough for you. Sorry.
As for me, I finally got all Cloudstone I needed (ended up with 99 shards with Thomas and 83 myself :P). I still 1 Pure Moonlighstone (3-3 CG) and 2 chunks of Cloudstone. But I can get those on my next playthrough.
Now I just need to beat 1-4 (already took care of the blue dragon) and finish the game a second time. Im lvl 148 I think now.
@lestat - does my stamina gets any bigger than 160?
