I'm making a tower for all my thaumcraft needs, and actually considering building it out of gold, silver, diamond and emerald blocks.
Too true. We built MFR lasers because we hadnt tried them before. Liked what we saw so built 5 of them. We are now processing the diamond ore in an industrial grinder and getting so much diamond dust we are using it instead of scrap in 3 of our matter fabricators. You can also see in the pic of our main floor that the half ceiling there is made of diamond, emerald, ruby and sapphire blocks.
