It is amazing that electrons‚ which can move at hundreds meters per second‚ can stay within the orbital of a 10-14 m atom. Diamonds and graphite are essentially the same in nature – carbon‚ but a difference between the arrangements – sp2 and sp3 hybridization – is all it needs to differentiate a luxurious jewelry from a humble pencil. Nature forms crystals in a similar way as an architect
