Yellow diamond genesis
The word diamond is derived from the Greek word Adamas, which means to be strong.
It is formed by pressure, fire, violence and timing, and only when all the conditions are right will carbon finally shine brightly.
When some of the carbon atoms in a diamond are replaced by nitrogen atoms (a hundred out of every million carbon atoms are replaced), the excess electrons form a new energy level in the forbidden band, and the diamond crystal begins to absorb blue and purple light, eventually giving the diamond a yellow diamond.
Yellow diamonds are usually light yellow, golden yellow, burgundy or amber and are the most common colors in colored diamonds, especially golden yellow.
Distribution of yellow diamonds in production areas
Yellow diamonds are widely sourced, but diamonds with deep yellow tones are mainly found in southern and central Africa.
