Types of Diamond

Diamonds are classified broadly under the categories of Natural Diamond, Synthetic Industrial Diamond and Thin Film Diamonds on the basis of their process of origination.

Diamonds remain to be the most fascinating gift that a woman can ever dream about. The word “diamond” is derived from a Greek word “adamas” which stands for “invincible". Due to its atomic structure, diamond is the hardest natural matter. This expensive and translucent gem is made of carbon.

Natural Diamonds, as the name indicates, are diamonds which originate in nature. Natural Diamonds are further classified into four categories depending on the type and amount of impurities in them. They are:
  • The Type 1a: This type contains 0.3% of nitrogen and 98% of diamonds are of this type. They are either light yellow or brown in color because they absorb blue light.
  • The Type 1b: This type contains 500 ppm of nitrogen. They are yellow, orange, green or brown in color.
  • The Type 2a: This type contains little nitrogen and is almost free from all forms of impurities. This is the purest form of diamond and is generally colorless.
  • The Type 2b: This type is a rare type of natural diamond and contains very little amount of nitrogen. The diamonds of this type are bluish in color and amounts for 0.1% of all the diamonds taken together.








Next, Synthetic Industrial Diamonds are those which are produced artificially by the method of High Pressure High Temperature Synthesis. Under this process, graphite and catalysts are subject to tremendous hydraulic pressure and at the same time are exposed to high temperature for few hours. This automatically converts the graphite to diamond. Diamonds so produced are small in size and are best used as cutting and grinding equipments but their quality is so inferior that they can hardly be considered as gemstones. Hence, these diamonds are marked with industrial utility.

The third type of diamond is known as Thin Film Diamond. These types of diamonds are produced by a process called Chemical Vapor Deposition.





Color also plays an important role in differentiating diamonds. White ones are produced in all the mines across the world. Pink Diamonds are the most extraordinary of all. Similarly there are yellow diamonds, green diamonds, and blue diamonds, certain quantities of which are produced by the Argyle mine in Australia. This mine also accounts for 95% of the world’s pink diamond generation.
