what makes diamonds color???
This question even in its simplest form needs to be broken down into two seperate issues: A. The cause of the inherent color of a particular diamond ie the color of the uncut stone in its raw state. B. The cause of the apparent color ie the color we percieve when looking at a polished diamond through the table. A – In a perfect white stone the daylight (whitelight) which leaves the stone is exactly the same as it was on entering, hence without color. However a yellow diamond will have absorbed some of the blue light within the visible spectrum (the primary colors from which white light is comprised of) so the light leaving the stone will appear more yellow. What is the difference between the two stones such that one is colorless and the other yellow? What caused the yellow stone to take away the blue light? Basically this absorption of certain wavelengths of the visible light spectrum is due to deformations within the crystal lattice. Lattice deformations are caused by three main facto
