40 Malachite, 60 moonstone. The Armor would certainly take him a long time, but if we're going by more realistic measures than I suppose Malakaus could attempt a more "Mass Produced" method, though they'd much less refined. He'd pretty much just pour molten malachite into blade molds and sharpen them carefully, and they certainly wouldn't look anything like the more detailed glass blades of Skyrim. They'd look more like what you'd find in Oblivion, but with less ornate handles.
