The fact that fluorescence is abundant throughout nature makes it only natural that a tray of loose diamonds would have some fluorescence in it. Diamond collectors and investors worry about this fact, and research has indicated fluorescence increased a diamonds value if blue was dominant. Yellow in all color tones lowered a diamond's value by 10-15%. A problem for us all is few blue diamonds come to a world diamond market abundant in canary yellow diamonds.
Of course, one could assume if the situation was the reverse and we had many blue diamonds and few yellow diamonds, then blue diamonds would be in the bargain bin and canary yellow diamonds would reign supreme. But that is not the case, and scarce blue tinged diamonds can melt the heart and wallet of the sweetest Santa. It is worth noting that diamond price and quality are decided by four values: color, clarity, cutting and carat weight. A more popular way is to look into the spirit of the diamond, and consider to determine and appreciate its beauty.
So by the most popular way,in a diamond one should look first for cut and proportion, color, clarity, and carat weight. Enjoy the search and reap tbe benefits. A diamond is credited for magical powers, and is one of a rare few items any place. Remember, if a diamond you are considering is accompanied by a diamond rating report. It will be issued by GIA or some accepted diamond rating agency. It takes an ultraviolet light to bring out the fluorescence in a diamond. You can say a white diamond can take on a blueish tinge under a certain light.
As example, a white diamond can appear brilliantly clear during the daytime, indoors or outside. But in a darkened kitchen under fluorescent you would see your brilliant white diamond transform into a light show of dazzling blue streaks running through the white. There are ultraviolet wavelenghts and radiation all around us. It is only under the actual ultraviolet light that you can see the extent of ultraviolet around you. So you should recall that ultraviolet radation and fluorescence is around us, all the time.
The ultraviolet radiation is in various properties and strenghts. it is in the outside sunshine and the source of sunburns and in more serious cases skin and other cancers. Happily the tiny blue radiation in your diamond does not have any such power.It gives its all to lightly, meekly, transform a perfect sunset while you watch blue light magic sparkle in your perfect diamond. A diamond what may appear white in the outside daylight may change when you enter an office building, with overhead fluorescent lighting. Have fun.
