The diamond clarity is an extremely important determinant of a diamond’s value. This characteristic of a diamond refers to the inclusions of a stone. The inclusions relate to appearance of foreign materials or another diamond crystal appearing in the diamond. Cracks also affect the clarity and can also affect this characteristic of a diamond, because they sometime appear whitish or cloudy.

Features Of Diamond Clarity

Some of the features of clarity that influence its affect on the value of the stone are size, orientation,, number, color, visibility, and the location. The diamond is examined under 10x magnification in order to determine what the clarity grade will be. Inclusions do not always minimize a stone’s value. Its performance or the structural integrity are not always compromised by these inclusions. Some of the imperfections such as large clouds will damage the diamond’s transmitting and light scattering ability. A stone’s possibility of fracturing is increased by any large crack that exists close to the surface, especially if the crack breaks the surface.

Usefulness Of Diamond Clarity

The higher the clarity grade, the more valuable the diamond. Inclusions can be useful as identifiers for a diamond similar to the way fingerprints are used in identifying humans as long as they are small enough to be considered minor. Also, these minor defects are used to differentiate between natural and synthetic gems, because technology is increasing the ability to manufacture the unrealistic faux gem

Inclusions and Blemishes Found in Diamond Clarity

Inclusions or “internal characteristics” as they are referred to in the diamond industry are clouds, feathers, included crystals or minerals, internal graining, cavities, knots, cleavage, and bearding. Blemishes are characterized as scratches, grain boundaries, naturals, chips, pits, and nicks. All of these features are assessed to determine the ultimate value of the gem.

The all inclusive system was established by the Gemological Institute of America which decided on the three areas to be evaluated in determining a stone’s value. These three aspects or areas are make, color, and clarity. The development of this system allows for consistency in the grading of diamonds. Prior to the development of this system, there were nine grades used in evaluating a diamond. The diamond grading scale today has six categories plus eleven grades. Included in the clarity category and grades are flawless and internally flawless with four other categories. The Gemological Institute of America has a specific grading system employed to make a determination of diamond clarity which involves special microscopes equipped with dark field illumination as well as an ultraviolet light. The light is a filtered overhead light. Other grading organizations use the same grading procedures including, the International Gemological Institute and the American Gemological Society. Uniform use of a grading system industry wide insures consistency in the valuation of the stones. Diamond clarity is finally determined by several clarity factors which include size, number, position, nature,, color or relief, rarity and value, and finally clarity enhancement which is created by a laser process and an acid wash to remove the coloring agent used in this procedure.
