Beyond their modern representations as the stone of marriage and commitment, diamonds have also represented faithfulness, purity and innocence. Diamond is the traditional birthstone for the month of April, and is heralded as the stone of purity and constancy. It is thought to be the gemstone of the intellect, preventing misunderstandings (romantic and otherwise). Diamond is also believed to provide clarity of thought, encouraging the resolution of problems which comes with clear understanding.

Diamonds are found in many areas around the world, including South Africa, India, Russia, Brazil, Australia, Canada and the state of Arkansas in the USA. Compressed and heated by immense forces, diamonds are formed deep in the mantle of the planet before being brought to the surface by powerful volcanic and geological activity. There are also types of diamond (called carbonado, lonsdaleite or hexagonal diamond) found in meteorites, though these are usually very small and can have a different atomical structure than planet-formed diamond.
