摘要

While a diamond may be for ever, its value is far from set in stone. It depends on the four Cs: carat, cut, colour and clarity. But while the first three can be measured objectively, assessing a diamond's clarity involves a certain amount of subjectivity and can leave experts disagreeing about the grade— and hence the value-of a stone. Now researchers at Cambridge University's Institute for Manufacturing claim to have devised a way to make the grading of diamonds and other precious stones more consistent. Tony Holden, the project's leader, says automating this process could do more than just lead to more accurate valuations. It could also make rough stones more valuable, by reducing the amount of waste during cutting.
