Diamond Education:
In selecting a diamond, the rarity, value and beauty is determined by the four factors mentioned above, called the 4C’s: Carat Weight , Color , Clarity , and Cut (proportions & finish). Today, many consumers are aware of the 4C’s, however, understanding how they determine value is important to discover what appeals to you in selecting a diamond, and getting the most for your money.
​
Carat Weight
Carat weight refers to the size of the diamond. Based on a standard unit of measure, one carat is divided into 100 points. The term originated from carob seeds that were used to balance scales in ancient times.
​
Color
The most desirable diamonds are colorless because the absence of color enhances the diamond’s ability to reflect a rainbow of color. Diamonds are graded on a scale of D (almost clear white) to Z
​
Clarity
Diamonds can contain slight imperfections. Often invisible to the naked eye, these natural birthmarks fall into two categories-inclusions (internal) and blemishes (external). Fewer inclusions increase the value of the stone.
​
Cut
Cut gives the diamond its brilliance. Of the four C’s, it’s the only one dependent on a human touch. Using precise mathematical formulas, the cutter transforms a diamond in the rough into a sparkling jewel that reflects and refracts light.

Finding the right diamond for you
To understand how the 4C’s work together to determine a diamond’s rarity and value, consider this diagram, like a classic balance. For a given PRICE (the fulcrum), you balance the (Carat Weight) on the left side and (Color, Clarity, and Cutting) on the right side. To select a larger size for a given price, to stay in balance, you would choose a less rare quality diamond. To select a rarer quality diamond, to stay in balance, you would choose a smaller size.
​
The combination of the 4C’s is strictly personal preference. By understanding this information, you can make the best choice. Realize that Carat Weight affects the value by about 10-20% per step up or down in size, Color/Clarity by about 10-15% per/grade, and Cut Quality can affect value by a considerable amount (25-50%), as it is almost completely controlled by the cutter.
