Diamond

"Diamonds are NOT a miner’s best friend, NOT a blue gleam in the darkness that you can use to craft the best stuff. NOT the pickaxes that can hack through obsidian, NOT the swords that can hack through wither skeletons, NOT the armour that can withstand the force of 1000 spiders. Diamond is NOT the best!"

Trivia

 * Diamonds are a well-known item because they are one of the most shown things on merchandise.
 * In real life, diamond is very fragile in certain directions, so it is not a good material for suits of armor. They are, however, commonly used for industrial purposes, generally as diamond-tipped drill bits and saw blades. They are usually used for cutting stone and other hard materials.
