    Two substances that may be harder (it's controversial) are Wurtzite (synthetic boron nitride) and Lonsdaleite (from meteorites).  But they don't fit your definition anyway!

    Although diamonds commonly known as the hardest material in the world, there are actually six materials that are harder. Diamonds are still one of the hardest naturally occurring and abundant materials on Earth, but these six materials all have it beat. (only the two below are naturally occurring)

    Diamonds remain the most scratch-resistant material known to humanity.

    hardest naturally occurring materials:

    Wurtzite boron nitride.

    Lonsdaleite, carbon with a strange crystalline structure, produced when a meteor hits earth.
