Diamond color actually refers to the colorlessness of a diamond. Although many diamonds appear to be colorless, most exhibit at least hints of yellow or brown. The more yellow the stone, the less value. The color of a diamond has a huge impact on its value. The most desirable diamond color is actually the colorless grade.
The diamond color scale was devised by the Gemological Institute of America (GIA) in the mid 1950's to regulate and define the color spectrum of diamonds. The GIA proposed starting at D as the best and most colorless diamond available. Why D and not A ? well just in case anything better is ever found. The color scale progresses through the alphabet from D until Z which is the most colorful diamond. The graphic below illustrates the GIA color scale.
To help you choose the diamond color that is perfect for you, we have collated a few top tips
For multi-stone items of diamond jewelry such as diamond earrings, diamond eternity rings, Multi-stone pendants etc. we provide a Austen Blake & EGL Jewellery Certificate of Authenticity which confirms the combined diamond carat weight and diamond quality for your peace of mind in the quality of your diamond jewelry purchase. As Multi-Stone Diamond jewelry has many diamonds, we offer a range of grading options like color grades D-E, F-G, H-I. It is very difficult to source the specific grade diamond, when many diamonds need to match together exactly.
Fluorescence refers to a diamond's tendency to emit a soft color glow when subjected to ultraviolet light (such as a "black light"). Roughly 30% of diamonds fluoresce to some degree.
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 (upside down). In the table up position, diamonds of Strong or Very Strong fluorescence appeared to have better color than less fluorescent stones. The effect was most noticeable in the I-K colors.
The visible effects of faint to medium fluorescence are perceptible only to a gemmologist using a special UV light source.
Because the fluorescent glow is usually blue (which is the complementary color to yellow) fluorescence can make diamonds of H-I color appear up to one grade whiter. For this reason, H-I diamonds tend to sell at a slight premium when they possess Medium to Very Strong fluorescence. Overall, fluorescence should not be a major factor in the diamond purchase since its effects on appearance are negligible, if not slightly positive.
