Spawning Items with colons!
Ever wanted to spawn lapis? Well it's actually possible, and very simple. No you can't just do /give @p lapis_lazuli, you have to do this:

/give @p <Item> <Amount> <Datatag>

For example

/give @p stone 64 2
            ^^^
That command will give you polished granite.

Go test it! copy and paste the example. If you can't find the ids, go Here!
