Definition: A glimmering glass-like mineral that is an allotrope of carbon in which each atom is surrounded by four others in the form of a tetrahedron.

Alright class, settle down now, let’s delve with a bow! We have a question today, quite sparkly and bright – what does ‘diamonds’ truly write? The dictionary gives us a clue, a scientific view, "A glimmering glass-like mineral," that's certainly true. But hold on just a moment, let’s break it down with care, It’s not like glass at all, beyond compare! “An allotrope of carbon,” you see, Means it’s made of carbon – perfectly! And each little atom, so small and keen, Is hugged by four others, a geometric scene. Think of a pyramid, a shape so neat, A tetrahedron forming, oh so sweet! Four sides surrounding, a stable design, That's the secret of diamonds, truly divine! So remember this lesson, don’t you see? Diamonds are carbon, beautifully free, Formed in pressure and heat, for all eternity! Any questions bubbling up, my dear students bright?
