Abstract

A method and apparatus to localizing inclusions in a diamond, wherein said diamond is fixed on a holder, said diamond on the holder is observed under a predetermined angle to obtain an image, further a second measurement is carried out to obtain two data to be calculated in a computer, said second data can be obtained by a depth measurement, or by changing the direction of observation to said diamond, in order to localize the inclusion with respect to the outer surface of said diamond. <IMAGE>
