Round-Shaped Diamonds - The 4 C’s

Cut — Although the two terms are often used interchangeably, there is a difference between the “cut” and “shape” of a diamond. The shape of a diamond (round, in this case) refers to its physical appearance, while the cut refers to how well the diamond’s features interact with light. Clean Origin only offers diamonds at or above a “good” cut quality. Good, very good, excellent or ideal are the four available options. When choosing the cut of a round diamond, keep in mind that the higher the grade the cut is, the more brilliant it will appear. It is also important that the cut is neither too deep nor too shallow; a well-proportioned cut reflects light flawlessly.

Clarity — Clarity, which refers to the number of inclusions and blemishes in a stone, is particularly important in round diamonds. Each diamond will have a different amount of these flaws, ranging from SI2 (having the largest amount) to VVS1 (having the least). Because of the shape and cut of a round diamond, any flaws will stick out; a high level of clarity is one of the most important factors to consider when you pick out your stone.

Color — In this case, color refers to the absence of color in a diamond. Clean Origin only offers diamonds from J to D, though there are diamonds with color from Z (containing the most color) to D (containing the least color). Color is hard to detect in round diamonds because they reflect so much light, which means that as long as it looks good to you, your significant other will love it, too.

Carat — While you can choose whichever color you like, round diamonds look their carat size, especially if you place them in solitaire settings. Unless you decide to make your round diamond appear larger by placing it in a halo, you’ll need to choose a larger carat size to wow your bride-to-be. However, by purchasing a lab-grown diamond, you can save 20-30% on the price—enough to substantially increase carat size.

Buyers Tips for Round-Shaped Diamonds

While round diamonds don’t highlight color differences, clarity and carat size must be chosen carefully. Perform an “eye test” on the diamond, determining whether you can see any flaws within the stone; if you can’t detect any, chances are no one else will either. Carat size is another key thing to consider: with no fancy cut to hide behind, it can be clear whether the diamond is large or small. If you don’t have the budget to purchase a larger carat diamond, pair it with a halo setting; tiny diamonds encircling her main stone will make it appear larger than it actually is.

Round Lab-Grown Diamonds

Because lab-grown diamonds have the same chemical construction and appearance as mined diamonds, they are graded the same way. When comparing the two types of round diamonds, you will look for the same qualities in cut, clarity, color, and carat. However, because they rely on a shorter supply chain, lab-grown diamonds can offer the same qualities as mined diamonds at a 20-30% lower price, allowing purchasers to increase carat size and thoroughly impress their loved one.

Often confused with cut, the shape of a diamond is the physical appearance that it takes. The most popular shape is the round brilliant.
The cut of a diamond determines how effectively light that enters the stone is refracted within and reflected back through the top of the diamond, providing sparkle. The best cut grade is defined as Ideal, followed by Excellent, Very Good, Good, and Fair. Fancy shape stones often do not receive cut grades and will be listed as 'None.'
Carat refers to the actual weight of a diamond and is a unit of measure equal to 0.2 grams. In all diamonds, carat weight is a large contributor to the price of the stone.
The color in diamonds is actually the absence of color, graded on an alphabetical scale from D to Z, with D being a colorless diamond and Z being yellow.
Clarity measures the amount of inclusions or imperfections found in a diamond. The best clarity is VVS1 followed by VVS2, VS1, VS2, SI1, and SI2. Although other levels of clarity exist, we only carry diamonds with quality we can stand behind.
