Diamond type is a method of scientifically classifying diamonds by their chemical impurities. There are four types of diamonds: Type Ia, Type Ib, Type IIa, and Type IIb. But does the perfect choice exist? Does the perfect diamond exist? Keep reading and you will know it. 




The type IIA is commonly known as "Golconda Diamonds" is almost devoid of impurities, they are normally colorless but they can also be gray, light brown, light yellow or light pink. Among all diamonds, type IIa is chemically the purest.


Diamonds with no visible absorption, no nitrogen impurities. This type of diamonds is formed under remarkably high pressure for longer periods for that these tend to have an irregular shape.
But like all in life: The rarest, the valuable. That is why it is the superior choice for investment. 


The "perfect" diamond is the type IIa, with D color, no fluorescence and IF or VVS1 clarity.

There are lots of famous diamonds of this type, such as The Cullinan, The Koh-i-Noor , Hope Diamond, The Graff Pink  or the known De Beer Millennium Star.
