Four parameters specify the quality of diamond. These are cut, clarity, colour, weight. The categories for colour and clarity are reproduced here. The weight of diamond is expressed in carats, one carat being 0.2 g. Cut is too complicated to express in a book on QoS of telecommunications. Readers interested in this aspect are invited to read the manual referenced at the end of these tables.
