Traditionally raw diamonds are first polished to enable experts to examine the interior and decide how to cut them. The result is up to 50% of waste.

An Indian company Lexus, in cooperation with a Russian software company OctoNus, have now found a way to short cut this process by viewing raw diamonds while immersed in molten glass. This reduces the waste to nearer 25%.

Will this bring down the cost of diamonds? Don’t use them myself, but don’t hold your breath. Dennis.
