Carat, Clarity, Color, and Cut. Carat weight is the weight of the diamond - one carat equals about .2 grams. Clarity is how clear or see-through the diamond is. The color of diamonds can be just about anything, but generally they are clear or a light yellow. The cut of a diamond is how proportionate and symmetrical it is.
This person is called a gemologist. There may be a sub-definition of this job title particular to one who selects diamonds all day, but overall, this person trained and is probably certified as a gemologist.Read more, below.
Your answer depends on who's doing the sorting. For example, as a consumer, when you want to find a pair of matching diamonds for a pair of earrings, you'll look for diamonds that are about the same size. If your purchase is an investment in any way, you'll also select two diamonds that are of the same colour, clarity and a near match in carat weight. Of course, the cut would necessarily be the same. A jeweler or certified gemologist can help you sort diamonds until you find the pair you want to buy. A diamond broker, such as DeBeers, for example, sorts diamonds according to a completely -- and quite mysterious/ undocumented -- different criteria.
The 4 C's of diamond grading include the carat weight, cut, color and clarity. When one decides to buy a 4 C's diamond, one should consider the cut of the diamond, which is how the diamond appears in terms of proportions and brightness.
Diamonds are classified based on the 4Cs: cut, color, clarity, and carat weight. Cut refers to the proportions, symmetry, and polish of the diamond. Color is graded based on the absence of color, with the highest grade being D (colorless) to Z (light yellow or brown). Clarity measures the presence of internal or external flaws, with the scale ranging from Flawless (no inclusions or blemishes) to Included (visible flaws). Carat weight measures the size of the diamond.
Diamonds do not have an odor.
The 4Cs of Diamond quality are four parameters on which the quality and price of a diamond are decided. These 4Cs are Color, Clarity, Cut, and Carat weight. These four parameters help you find the best-suited diamond for you. You can find more information about this 4Cs on our website highglow
The 4Cs of a diamond wedding or engagement ring are the following: Carats, which refers to the weight of the diamond; Cut, the depth and width of the stone; Clarity, which rates the blemishes and inclusions in the diamond; and of course, Color. The 4Cs rating system was developed by the Gemological Institute of America (GIA) in the 1940s and 1950s as a way for one to objectively compare and evaluate diamonds. This system is still used today by both professional jewelers and consumers when shopping for diamonds, and more specifically, wedding and engagement rings.
Natural diamonds can be industrial diamonds or gemstone quality diamonds. Gemstone quality diamonds are worth more than industrial diamonds. If by 'industrial', you mean man-made, then a natural diamond will always be more valuable than a man-made diamond of equal carat weight, unless the natural diamond is not of gemstone quality.

If you're buying a diamond and believe that you fully understand the 4Cs of the stone, you can ask for a gemological expert's report, you can witness a probe used by the jeweler to verify that the stone is indeed a diamond.
Congratulations on your engagement! Diamonds are graded on the 4Cs: Color, Cut, Clarity, and Carat weight. A very high quality diamond is near colorless, ideally cut to reflect its brilliance, and has minimal scars or marks affecting its clarity. In addition to the 4C's many people are becoming aware of the provenance of diamonds. Many diamonds are mined in countries that exploit their workers, forcing them to work in terrible, dangerous conditions. For very high quality diamonds that are ethically mined, I would recommend checking out http://www.brilliantearth.com/.

Natural diamonds tend to hold their value because they are rare, formed over billions of years, and available in limited supply. Their worth is mainly determined by the “4Cs” — cut, color, clarity, and carat weight — along with factors like certification, origin, and market demand. High-quality natural diamonds, especially rare shapes, larger stones, or vintage pieces, often remain desirable to collectors, investors, and jewelry buyers. While market prices can fluctuate, truly well-graded natural diamonds continue to retain long-term appeal and value.
The best way to buy or sell small diamonds is to focus on quality and trust. When buying, check the basic 4Cs (cut, clarity, color, carat) and compare prices from trusted sellers. When selling, get a quick appraisal and compare offers from reliable buyers to ensure a fair price. 👉 Always choose trusted sources and compare options to get the best value.
Classification is more commonly called "grading". Diamonds are graded or certified depending mainly on the 4Cs -- color, cut, clarity, and carat. The Gemological Institute of America (GIA) developed the diamond graded system now used internationally. They have a website for consumers that explains well what the 4Cs are and how they are determined.
Diamonds are judged based on the 4Cs: cut, color, clarity, and carat weight. The cut refers to how well the diamond is shaped and faceted to reflect light, while color grades range from colorless to light yellow. Clarity measures the presence of inclusions or blemishes, and carat weight refers to the size of the diamond.
