Pink OriginPink diamonds have only been found in a few mines across the world. The rich Golconda region in India and the Minas Gerais region of Brazil produced notable diamonds in the 17th and 18th centuries. Today, the Argyle mine in Western Australia is the source of the vast majority of the worlds supply. It is famous for generating the hugely coveted full-bodied hot pink diamonds.
Color FormationDiamonds become pink when heat and pressure deep within the earth cause the crystal lattice to distort. These distortions cause Pink Diamonds to absorb green light and hence impart a pink color. This can often be seen as in parallel bands within the diamond. Pink Diamonds may be modifi ed by an orange, brown or purplish color.
Strength Of ColorThe strength of color is one of the most important factors in determining the value of a natural color diamond. The value of a natural color diamond increases with the intensity of the most prominent color within the diamond.
