Captivating, charming, classic, chic… Those are the 4Cs, right? No, the real 4Cs – carat, cut, clarity and color – are the factors used to determine a diamond’s quality and value. The four components are essentially what give a stone its sparkle and fire. They also help us estimate the cost or resale price of a stone.
Understanding the 4 Cs is priceless if you will be shopping. This guide will empower you to verify the quality and value of the diamond you are purchasing.
Understanding the Four Factors of Diamond Quality
Helps us to answer the question, “How big is the diamond?” A carat is a measurement that jewelers use to calculate the size of the stone. Typically, the larger the carat weight, the higher the price, because larger diamonds are more rare.
If you see a ring that is described as “total carat weight,” this is the total of all the diamonds in the ring added up. A smart way to get a larger overall ring on a smaller budget is to choose one with several diamonds instead of just one solitaire. For example, a 2-carat total weight diamond ring with a smaller center stone and several side diamonds is generally much less expensive than a 2-carat solitaire, even though it offers the same amount of carat weight.
The cut of diamonds varies greatly from one to the next, and the price changes with it. The round cut is the most common cut, but other, more exotic cuts like the brilliant or cushion cut may be more expensive. This is because it takes longer to make more complex cuts and these cuts demand a higher quality stone in order to showcase the expected fire and sparkle.
The other aspect of this C refers to the quality of a cut. According to the GIA, the cut of a diamond is graded from “excellent” to “poor.” This is often the most difficult grading factor for a regular shopper to understand. Each diamond shape has set proportions that it should respect in order to maximize its shiny qualities. The cuts that fit these dimensions rank higher up on the scale. For example, shallow cut diamonds, though they may look larger from the top, are an example of a less-than-perfect cut.
Carat weight and cut are joined by clarity in properly reviewing a diamond’s quality. Stones are rarely perfect, even if it looks flawless to the naked eye.
It’s important to note that even a slightly included stone can provide exquisite brilliance and make a bold statement. It won’t be as transparent, fiery or expensive, as a stone with a higher grade, however. Aim to buy as clear a stone as your budget will allow for optimum opulence.
Finally, the fourth C of color comes into play. Most diamond shoppers can see if a diamond is nearly colorless or if it has an off-white hue.
The diamond color scale starts at D, or colorless, and ends at Z, which is a light-yellow color. Diamonds on the lower end of the scale – especially D, E and F – are practically lacking in color, which enhances the diamond’s overall dazzle. The cost of these diamonds reflects their rarity. Buyers on a budget may look at stones in the G or H category to invest in a more cost-effective stone.
