FAQ FANCY COLOR DIAMONDS
Q :- Are colored diamonds natural and are colored diamonds real?
Q :- Which colored diamonds are the rarest?
Q :- When is a colored diamond a “fancy color diamond”?
Q :- How do colored diamonds get their color?
The chemistry of colored diamonds :
Each gem has its own unique story to tell, but all colored diamonds owe their appearance to several fundamental scientific reaction as follow :
- Yellow and Orange color : The nitrogen atoms within these diamonds have assembled themselves in such a way that blue light is absorbed and yellowish hues are reflected and a specific grouping of nitrogen atoms is also responsible for the shading of orange diamonds, but will absorb light in both the blue and yellow spectrums.
- Pink and Red color : When the stones are still embedded in the earths crust,Intense heat and pressure cause there crystal lattice to distorts and absorb a particular band of green light rays. Ultra-rare red diamonds, which are essentially just deeply colored pink diamonds, have the same cause of color.
- Green color : It's not until the last leg of their journey to the earth's surface that diamonds get their green color. Just as they are about to leave the uppermost layer of the crust, these stones absorbs naturally occurring radiation, which causes them to reflect a green hue by absorbing red and yellow light.
- Blue color : Boron is the active ingredient in blue colored diamonds, bonding with carbon to absorb red, yellow and green light.
- Purple and Violet color : Purple colored diamonds are also the product of lattice distortion, but emerging evidence suggests that the presence of hydrogen may also contribute to their shading.
