Fancy color diamonds include yellow, blue, pink, green, red, and a
few others. The color of most diamonds comes from trace particle
impurities that are present in the carbon lattice structure of the stone
as it grows below the Earth. The most common trace element in
diamonds is nitrogen, which imparts a yellowish or brown tint to the
diamonds, depending on its concentration. Diamonds with nitrogen
impurities are called Type Ia diamonds, and represent about 98% of
all gem-quality natural stones in the world. Even D-color diamonds
can have trace amounts of nitrogen, but the concentration is so
small that it cannot be detected without sophisticated lab
equipment.

• In simple terms, exploration companies take a series of samples
from a kimberlite target, with each one getting gradually larger
and more expensive. Each type of test is designed to assess
different variables, depending on the stage of exploration. Since
sampling is expensive, companies often have to raise additional
financing before continuing on to the next phase of testing, and
the previous results must be positive to ensure that they can raise
sufficient capital to continue.

If the nitrogen atoms are dispersed throughout the crystal in isolated
sites (not paired or grouped), they can create the range of strong
yellow colors that qualify as fancy yellow. Of all the fancy diamond
color groups, yellow is by far the most common, and therefore the
least expensive. However, the ‘canary’ yellow colors still represent
less than 0.1% of all gem-quality diamonds.
Blue diamonds, second only to red in terms of their rarity, are
caused by boron impurities in the stone. Since boron is much less
abundant on Earth than nitrogen, blue diamonds are extremely rare.
Purple stones are caused by a combination of crystal lattice
distortion combined with a high concentration of hydrogen.
