Diamond color has a significant impact on its value. To ensure the highest
quality diamonds for your selection Adiamor 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.
