All diamonds can be classified into two main categories which are referred to as ‘types’, depending on the trace elements that are naturally present within the carbon crystal structure of the diamond. Type I diamonds contain small amounts of nitrogen whereas Type II diamonds do not. Each of these types is then subdivided further and the term Type IIA is used to denote the very purest diamonds. This means there are no measurable impurities in the diamond of any kind which makes these stones exceptionally rare, they make up less than 2% of all gem quality diamonds found worldwide. Not only can these stones be perfectly colourless but they also possess an exceptional level of transparency which enhances their beauty and allows the brilliance and fire of the diamond to be appreciated to the fullest.
Famous examples of Type IIA diamonds include the Koh-i-Noor and the Cullinan, which are part of the Crown Jewels, as well as the Krupp diamond which Richard Burton bought for Elizabeth Taylor and was later renamed the Elizabeth Taylor Diamond.
