Diamonds are ranked based on the 4 Cs: cut, color, clarity, and carat weight. The Gemological Institute of America (GIA) is a reputable organization that provides grading and certification for diamonds, which helps establish their quality and value. Diamonds are not ranked globally in a single list, as different organizations may use their own criteria for evaluating diamonds.

Generally pink diamonds are found in Australia. Australia's Argyle mine, in far north Western Australia, produces around 90% of the world's supply of pink diamonds. These are the world's only "intense" pink diamonds. Pink diamonds, one of the most rare and expensive diamonds in the world, are also mined in India, Brazil and Africa, but these are lighter in colour.

Diamonds are the hardest mineral/gem in the world but they are brittle. The next step down from diamonds are sapphires and rubies. They arent brittle and are quite hard.
