Did you know that the world’s  most valuable diamonds are  red? Only the wealthiest  people can afford them. Think  about this: God owns all the  diamonds in the world. How  rich He must be! Diamonds come in many colors:  red, yellow, orange, green,  blue, pink, purple, brown,  gray, black, and white. How do  they get that way, and where  do they come from? Click the  diamonds to find out.
YELLOW Where: Yellow diamonds are found in the ground all around the world. Why: A fancy yellow diamond gets its color from small amounts of nitrogen in its crystal structure (lattice).

ORANGE Where: Mostly South America and Western Australia Why: Like yellow diamonds, orange shades come from nitrogen in a diamond’s crystal.
GREEN Where: Mostly South America or Africa Why: Green diamonds come from rocks with radioactive material inside (such as thorium or uranium). When radiation enters a diamond, it can knock electrons or carbon atoms out of place. The lattice changes, and so does the color of the outer layer of the diamond.
BLUE Where: South Africa, India, Australia Why: Blue color comes from boron trapped in a diamond’s structure.
PINK Where: Almost all pink diamonds come from Australia’s Argyle Diamond Mine. Why: Intense heat and pressure changes the diamond’s crystal lattice, turning the diamond pink.
BROWN Where: Brazil, Angola,  the Congo, Borneo, Australia Why: Brown is the most  common natural diamond  color. Great pressure deforms  the diamond’s structure. This  changes the way a diamond reflects  light and creates popular brown  diamond colors known as chocolate,  cognac (KOWN-yak), and champagne.
PURPLE Where: South Africa, Russia, Australia Why: Purple diamonds likely get their color from an unusual amount of hydrogen.
GRAY Where: Australia, South Africa, India, Russia, and Brazil Why: Gray diamonds have a high concentration of hydrogen and also sometimes some boron.
BLACK Where: Brazil and the Central African Republic Why: Black diamonds have usually been tainted with graphite, pyrite, or hematite.
Where: Australia, Africa, Botswana, Namibia, Venezuela, South America Why: These are different from colorless diamonds. They contain irregularities that change the way light passes through. The color of white diamonds might remind you more of milk than water.
WHITE
RED Where: Most come from Australia’s Argyle Diamond Mine. Some have been found in India, Russia, and South America. Why: No one is sure. The red might come from the way the diamond’s carbon atoms are twisted. This is called “carbon distortion.”
