Pink Diamond
Pink diamonds contain graining lines within their atomic structure caused by pressure beneath the Earth’s surface. This is referred to as ‘plastic deformation’, meaning the growth of the crystal lattice has been compressed, affecting the way light refracts within the gem. Scientists believe graining is due to the tremendous pressures to which diamonds are subjected under the earth’s surface. Different levels of graining will result in different shades and is also thought to produce red diamonds. With only an estimated decade of supply remaining, Pinks diamonds are becoming increasingly precious.
Please note that a significant amount of treated diamonds exist on the market. The purpose of the treatment is to increase the colour.
