The diamond measures 6.5 by 5.6 by 4 centimeters (2.5 by 2.2 by 1.6 inches). It's a Type IIa diamond: These are made almost completely of pure carbon, which makes them clear in color. While obviously incredibly valuable, it was impossible to price after the discovery: The stone couldn’t be inspected on site as it was larger than the scanner available. The price of a diamond depends on cutting, optimal shape, final color, and the presence of imperfections.
