The 4 C's

The quality of a diamond is defined by means of the 4 C’s: Carat, Clarity, Color and Cut. These characteristics do not only determine the stone’s quality, they can also be very useful in identifying the diamond, since every stone is unique.

CARAT WEIGHT

Carat refers to the weight of a diamond. One carat equals 0.2 grams. A carat is further subdivided in to 100 points. A stone of 1.50 carats thus means it weighs 1 carat and 50 points.

CLARITY

The clarity of a diamond is determined by the number, size, brightness and location of the internal and external characteristics, important structure phenomena and transparency. Generally speaking, mainly the inclusions in the stone affect the clarity. The fewer inclusions or structure phenomena the stone displays, the higher the quality of the diamond.

COLOR

Color intensity can vary from almost colorless, which is preferable, to decidedly yellow. The value of a white stone is higher than that of a yellowish stone.

CUT

Diamonds can have cut grades of Ideal, Very Good, Good, Fair, and Poor. The cut, or proportions and angles of a diamond, determine how it reflects light. A diamond’s reflective properties are referred to as fire or brilliance. Too shallow a cut will let light escape through the sides of the diamond before it has a chance to reflect, making it appear watery or dull, while too deep a cut will allow light to be lost through the bottom of the diamond, making it appear dark, especially in the center.

What Is The Clarity Enhancement Process?

This process takes a diamond with a visible imperfection and makes the imperfection much less visible to the naked eye. During the clarity enhancement process, we insert a microscopic amount of material into the part of the diamond that contains a feather. This material has the same optical properties as the diamond itself. When light travels from one medium to another, it either changes its course or reflects in a different direction. When light attempts to pass through a non-enhanced diamond that has a feather, the light hits the feather and reflects off in any number of directions. That is why we see the feather, and the diamond doesn’t appear to be clean. With a Clarity Enhanced diamond, the light passes through the natural feather because the material used for the enhancement has the same optical characteristics as the diamond. 

Does Clarity Enhancement "Change" A Diamond In Any Way?

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 diamond is exposed to high heat or strong acids and bases, the enhancement may be reversed. In the extremely rare case that a diamond should lose its enhancement without being exposed to high heat, Diamond Jewelry United will re-enhance the diamond free of charge. With each diamond sold, DJU provides an apprasial with characterisitics of the diamond which is also our lifetime guarantee. Diamond Jewelry United can offer you visually stunning diamonds for a price 70 - 80% less than similar looking non-enhanced diamonds.
