Diamond by Sachien

One day when I was a wee lad, I uncovered a valuable discovery.

Here is the story:

I was a just a squalid miner boy. I decided to dig down deep into the mineshaft. Me and my pickaxes. I hit the bedrock layer. There I faced a fear, magma. I forgot about the danger and dug. The night fell and I mined a room to rest. Bang! my pickaxe broke. " Good thing I brought spares" I finally realised. What was it? I rinsed away the dust. The light was so bright, I trembled. I hit diamond. Diamond absolutely everywhere.
