A 4Cs lab diamonds– Cut, Colour, Clarity and Carat weight – determine its unique beauty and value. In general, the best diamonds feature flawless performance across all four components.
However, each individual differs in how much importance they place on each component. For instance, some might prefer a lower clarity grade over poorer colour quality.
Cut
Cut is the term used to refer to a diamond 4C’s chart proportions and symmetry which determine its brilliance and how much light it reflects off of it. A well-cut diamond will reflect light while poorly cut diamonds may look dull or glassy – in fact, diamond cut is one of the key determinants of beauty and value of a gemstone; any differences in clarity grading or colour grade cannot compensate for poor cut quality.
American Gem Society (AGS) ranks diamond cuts according to an eight-step system that awards Ideal, Excellent, Very Good and Good grades. A well-cut diamond showcases both skill and craftsmanship of its cutter, who shapes and polishes it into its final form.
Carat refers to a diamond’s weight in carats; one carat weighs 0.2 grams. Carat weight doesn’t rank among the more critical characteristics, but it can still influence price; larger diamonds typically cost more.
Colour
Colour of diamonds ranges from an icy white hue to light yellow. Similar to clarity, its colour characteristics may have an adverse impact on its value; however, overall diamonds are valued for how well they reflect light; therefore colour should be an essential consideration when evaluating any gem newsintv.
Prior to 1953 when the Gemmological Institute of America (GIA) first instituted their D-to-Z colour grading system, diamond quality had many other designations ranging from A, B and C (without clear definition) through Arabic (0-1-3-0-III-4-4), Roman descriptive terms like Gem Blue or Blue White. Now with GIA’s universal D-to-Z scale in place, jewellers, diamond vendors, buyers worldwide and diamond vendors all speak one common language regarding diamond quality; combined with proper cut, colour grading or carat weight they help make diamond sparkle! But remember Ideal-cut is always preferable if your goal is truly sparkling diamond sparkle!
Clarity
Diamonds are among the few things in nature that aren’t perfect, with diamonds no exception. While in their formation these amazing gemstones will form their own individual characteristics – known as inclusions or flaws – which ultimately define its clarity famousbiography.
Diamonds that are free from flaws tend to be more brilliant and valuable. Gemmologists use a scale consisting of FL (flawless), VVS1-VVS2 (very, very slightly included), SI (slightly included) to I (included) as a gauge to classify diamonds’ clarity grades.
Note that even an exquisite diamond can still possess poor clarity characteristics even if its cut, colour and carat rating are ideal. For instance, light yellow diamonds with strong blue fluorescence may mask their yellow hue in sunlight to appear almost colourless – which is why GIA certification will identify all its unique attributes.
Carat
Carat refers to a diamond’s weight, measured in mill carats. One carat equals 0.2 grams. Carat alone doesn’t determine its price – other characteristics like colour, clarity and cut also influence its jmdhindi.
An effective way of understanding how a diamond’s carat weighs against its quality is comparing two similar-carat stones with different shapes; an optimally cut stone will reflect light more brilliantly than one with less sparkle, even if its carat weight is greater.
Conclusion
People tend to focus on carat weight when searching for diamonds, but it’s important to keep in mind that bigger doesn’t always equate to better. A diamond that does not adhere to all three Cs may contain hidden inclusions or lacklustre sparkle.
