R.I. is the comparative ability of a gem to bend, or refract light. It is expressed as the ratio of the velocity of light in air to its velocity in the substance e.g. diamond has an R.I. of 2.42. This means that light travels in air at a velocity 2.42 times its velocity in the diamond. Since R.I. is a measure of the optical density, the higher the R.I., the greater the degree of bending for the same angle of incidence. The optical density and therefore the strength of refraction vary from species to species. For a given species, the velocity at which light passes through is constant. The angle of refraction for any given angle of incidence is constant for every gem species, since the reduction in velocity determines the degree of refraction or bending of light, as it enters the gem. Refractive index can be measured by an instrument known as the refractometer, as well as by other simple methods to be discussed later. Total Internal Reflection and Critical Angle accurate d

The rough diamond sorting process is highly automated. After recovery, the diamonds are conveyed into a secured section of the plant where they enter sorting units—large metal canisters containing progressively smaller sieves down to 3 mm. At each sieve level, the diamonds are transferred into separate containers and packaged for shipment. The Diavik mine is jointly owned by Diavik Diamond Mines Inc. (a wholly owned subsidiary of Rio Tinto plc) and Dominion Diamond Diavik Limited Partnership (a wholly owned subsidiary of Dominion Diamond Corporation). From the mine, the sorted diamonds are flown to a product splitting facility near the Yellowknife airport, where they are divided between the two owners—60% to Rio Tinto and 40% to Dominion Diamonds. Rio Tinto.  This Anglo-Australian mining conglomerate owns a 60% stake in the Diavik mine, which produced 6.7 million carats in fiscal year 2015. It also owns a 100% stake in Australia’s Argyle diamond mine and sells that production in lots
