Clarity enhanced diamonds

The clarity, or purity, of a diamond refers to internal inclusions of the diamond, and is one of the 4-C's in determining a diamonds' value.

About Clarity Enhancement

Diamonds are classified into two major categories: "Natural" and "Enhanced". Both types of diamonds come from the same place which is inside the earth. They are then mined and cut for the consumer. Natural diamonds are those that are not enhanced in anyway. They have their own unique colors and characteristics. This is why natural diamonds are much more pricey. However, a enhanced diamond is a diamond that has flaws and through different enhancement processes. These processes make them just as unique as a natural diamond just at a much more cost effective. This means that you can get a larger enhanced diamond for the price of a much smaller natural diamond.

What is the Clarity Enhancement Process?

Several treatments are used to enhance the appearance of a diamond. One process is laser drilling or fracture drilling. There is also High Pressure High Temperature Treatment (HPHT). Laser drilling uses heat, or injects chemicals into the diamond, to make discolorations and small flaws less visible. Sometimes, laser drilling is followed with fracture filling to further decrease the visibility of small cracks. Fracture filling involves adding a glass-like resin into the diamond to close small cracks, making imperfections invisible to the human eye. In order to permanently alter the color of the diamond, HPHT may be used. This method of enhancing a diamond uses a cubic press to recreate the natural, diamond-forming conditions of the Earth. Depending on the chemicals involved, the diamond will either exhibit a fancy color or be colorless following the treatment.

Who invented this Clarity Enhancement Process?

In 1982, Zvi Yehuda, an extremely famous Israeli scientist discovered a way to enhance the clarity of diamonds. The revolutionary process optically eliminates "feathers", which naturally occur in most diamonds. 

Does Clarity Enhancement "alter" a diamond in any way? 

No, it is still a natural diamond. It's just a natural diamond that looks much better for a lower price. 

Do I need to give my enhanced diamond special treatment?

The Gemological Institute of America (G.I.A), after extensive research, has determined that normal wear and tear cannot harm the enhancement. Only if the enhanced diamond is exposed to high heat or strong acids and bases, the enhancement may be reversed. So, as long as you clean your diamond with a amonia free lightweight cleaner your diamond will be just fine.
