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.

where D is the highest color level, which represents complete colorlessness, and the lower the color level, the lower it is, the more yellow it is.
Among them, M-R belongs to the yellow category, which shows yellow color from any angle.
Diamonds of the S-Z grade can see a distinct yellow, but such diamonds can only be called diamonds with yellow tones with low color grades, and cannot be called yellow diamonds.
So, what kind of diamond can be called a yellow diamond?
Combined with ordinary diamond color grades, only yellow that exceeds Z color can be called Fancy (fancy), and yellow diamonds of general fancy color diamond grade, from low to high, are:
Fancy Light Yellow
Fancy Yellow
Fancy Intense Yellow

Because yellow diamonds only show their most intense color when they are cut into a non-round shape, it is easier to show the fire of yellow diamonds.
