A Sense of Strong Blue Fluorescence Diamond

The top D to F colored on GIA Color Grade Scale of strong blue fluorescence diamond has a better price around 12%. Even so, many seller of strong blue fluorescence diamond gave a special selling price for it. It is a fact that they little bit difficult to sell: The transparency of strong blue fluorescence diamond sometimes impaired and the body color of them often ‘over-graded’. So, a selling price of them depends on their notice-ability. For an appearance higher-color stone of milky white has a lower price than a strong blue fluorescence diamond, whiter and brighter. Usually, an appearance higher-color stone of yellow or milky white have a discount price range of 6% to 12%.

A research of strong blue fluorescence diamond has prepared by GIA (Gemological Institute of America). They published an article in 1997, a conclusion from both a continuous survey and sale perception that ultra-violet fluorescence has not well for an appearance of strong blue fluorescence diamond. A strong blue fluorescence diamond will increase an appearance. In the research, the advantages of strong blue fluorescence diamond in colorless to near-colorless was an evident as well; where the traders will give a bid of lower price for a better colors of moderate to highly strong blue fluorescence diamond.

One of the conclusions from GIA’s research is a tight relationship between a strong blue fluorescence diamond and appearance of color; it’s all about viewer’s position. For example: an appearance of strong blue fluorescence diamond has founded from a position of face up. So many viewers have not seen any transparency differences of a color set of strong blue fluorescence diamond. It’s happened because a typical of strong blue diamond: An appearance of hazy. A position of face up in both shaded sunlight and artificial light resulted a 30% - 55% of difference transparency. Indicated that a strong blue fluorescence diamond isn't less transparent, they will show up with an oily.

The factor of how we cut the strong blue diamond can affect an appearance of diamonds color as well. The best cut of strong blue fluorescence diamond would show up a best color. In general, a strong blue diamond has no a big effect on appearance by table-down’s view. In table-up’s view (usually for jewelry), a strong blue fluorescence diamond has a better appearance of color than non-strong blue fluorescence diamond.
