Azog kneels beside the nearest creature and drives his blade into one of its eyes. "I'm gonna assume that's about where it's head is. Just makin sure can't hurt. What say you we get a proper look around now, lads?" Reasured this one is dead, he move to the others, repeating the process.
Once sure they are all dead, he heads up the Northern stairway. "I'll make sure there are none more up this side. Could someone look up the southern stairwell? Look around as you like, but please don't touch the altar before i can get a good look at it. Something about it just doesn't look right."

Azog pockets the stones one by one, making sure everyone else is either busy or doesn't have line of sight to see him pick them up (IE. behind him, unable to see anything but general movement). Once up the stairs and alone, hopefully, he examines the stones closely. Hopefully his uneasiness about getting caught looting will translate into his lie about the altar.
