When speaking
of "white" diamonds, we're actually referring not to color, but
to its absence. Since the shades of diamonds can range from colorless to
a fairly obvious yellow coloring, an international scale has been established.
A colorless diamond is graded from "D" to "F", which
is incredibly rare. Most diamonds are tinged with some color, the most
common being yellow, brown or grey. It can be so slight it is nearly imperceptible
to the untrained human eye.
