Not all diamonds are white or colorless. Impurities give diamonds a shade of blue, red, orange, yellow, green and even black. Vivid blue, green and pink mined diamonds are the rarest. They are not the rarest gemstones, however. That title goes to a pure red ruby and real natural red rubies can be more expensive per carat than lesser quality diamonds. Diamonds actually are found in abundance; thousands are mined every year. 80% of them are not suitable for jewellery – they are used in industry or used on inexpensive rings.
