Diamond Color
Diamond color is one of the most important factors to
consider, as it is noticeable to the "naked" eye. A diamond's color is
graded by GIA on an alphabetical scale from D-Z, with D being
absolutely colorless and Z being light yellow. Beyond "Z", a diamond is
considered to be a "Fancy" color. Although many diamonds appear to be
colorless, the many of them have at least a hint of body color.

GIA and AGS Color Grading Scale
Diamond color has a significant impact on its value. To ensure the
highest quality diamonds for your selection IcedTime carries diamonds
in the color range from D-K only. When buying a diamond, take into
consideration that it is often very difficult to detect the difference
between a colorless diamond (D-F) and a near colorless diamond (G-J),
especially when it is mounted in jewelry. Diamonds with a K-Z color
grade usually have yellow shading that can be detected by the naked
eye, however, a well cut stone with good proportions will still release
the brilliance and fire of a lower colored diamond, dispersing light in
such a way so as to create a beautiful stone.
The Impact of Fluorescence
Fluorescence is not directly related to a diamond's color. This
separate characteristic refers to the diamond's ability to fluoresce
under ultraviolet (UV) light. Our sun emits some UV light, but it is
usually not great enough to detect fluorescence. When exposed to UV
light, many diamonds will give off a distinctive glowing blue
coloration. Although fluorescence may be displayed in various colors,
blue is the most common in diamonds. The fluorescence of a diamond is
defined by its intensity as either None, Faint, Medium, Strong, or Very
Strong. Although fluorescence is a characteristic that can be measured,
it is rarely an issue when selecting a diamond and is usually not
detectable to the eye.
The impact of fluorescence on price depends on its
noticeability. Faint fluorescence has very little effect on a diamond
of any color, and therefore has no effect on value. For some higher
color stones (D-G), strong fluorescence may give the stone a milky
white appearance, which greatly lowers value. Fluorescence often adds
value to lower color stones, such as I and lower, as it gives the
stones a whiter, brighter appearance.
