DIAMOND FLUORESCENCE
Across the breadth of 1.6 billion years, journeying from the crucible of the earth, emerges the most intriguing diamond in history. Revered for its exquisite beauty and provenance, the Argyle pink diamond is coveted as the most esteemed diamond in the world.
A study performed in 1997 by the GIA found that the level of fluorescence has no widely perceptible effect on the color appearance or transparency of diamonds when viewed table down. In the table up position, diamonds of Strong or Very Strong fluorescence appeared to have better color than less fluorescent stones.
Overall, diamond fluorescence should not be a major factor in the purchase of a diamond since its effects are negligible, if not slightly positive. The exception would be to exercise caution in purchasing a diamond with Strong fluorescence in D-F color diamonds or Very Strong fluorescence in G-H color diamonds and natural fancy colour diamonds (which do not possess enough body color to offset the degree of fluorescence).
