The Perfect Diamond For Your Diamond Ring

March 15, 2018

Established by the GIA, the leader in diamond grading, the Four C’s look to grade your diamond using four different criteria.

The First C: Color

When grading a diamond for color, expert jewelers look for not the types of color, but the absolute absence of any color in a diamond. Chemically pure diamonds are like a drop of absolutely pure and clean water. These will carry a higher grade, value, and price. The GIA uses a scale from D to Z that looks at the varying hues, or degree, of lack of color a diamond has, D being colorless and continues to increase in visual color to the letter Z.

The Second C: Clarity

The clarity of a diamond is graded based on the number of ‘inclusions’ or ‘blemishes’ found on and within the diamond, the size of these, and where they are located. When diamonds form, they will naturally form internal breaks, cracks, and other visible irregularities within the diamond, which is often referred to as inclusions. Often times, when a diamond is cut, mounted, or naturally externally worn down, ‘blemishes’ are formed. In general, ‘inclusions’ are internal while outside irregularities are ‘blemishes’. No diamond can be absolutely pure, but the closer to pure and absence of inclusions and blemishes, the more valuable and higher graded the diamond is. The GIA uses a 6-category grading system with some being divided into sub categories as well.

The Third C: Cut

Although the actual shape of the diamond is often referred to as a “Cut”, when grading the diamond, this actually refers to how well a diamond interacts and reflects the light around it. Cutting and shaping a diamond requires extreme care and precision, and proper cuts in specific places help give the diamond a bright and stand out shine. The GIA values and grades the Cut of a diamond in a few ways, often times referring to how bright the diamond reflects the white light within it back out, the “fire” or scattering effect of the white light into the colors of the rainbow, and the scintillation or the sparkle a diamond gives off and pattern of light it reflects.

The Fourth C: Carat Weight

The Carat, or carat weight, simply refers to how much the diamond weighs. When measuring the weight of a diamond, jewelers use the metric “Carat”, which can be broken down into 200 milligrams. Essentially, the more carats a diamond is, the more it conversely weighs, and the more valuable the diamond is. With larger diamonds, they are rarer and more in demand. The bigger the diamond and the more carats, the more it will cost. Although many judge diamonds based solely on the carat number alone, master jewelers understand the varying factors of each of the Four C’s in determining the value of a diamond.
