The 4Cs that set the standard for diamonds
auvnua .
★ Diamonds are an essential part of a diamond ring, combining both beauty and asset value. Each diamond has its unique characteristics, and the GIA (Gemological Institute of America) 4C grading system (Cut, Color, Clarity, Carat weight) is commonly used to distinguish these traits. Colored gemstones or similar stones can also be alternatives to diamonds.
★ Cut
- The cut of a diamond is crucial as it reflects the light passing through the diamond, determining its brilliance. Diamonds that are too thick or too thin fail to reflect light properly, resulting in a dim appearance. The cut is graded from Poor to Excellent based on brilliance and fire.
★ Color
- One of the factors determining a diamond's grade is its color scale, which ranges from completely colorless (D) to yellow (Z). The less color a diamond has, the higher its value. Common color grades for jewelry range from D to J.
★ Clarity
- Clarity indicates the transparency of a diamond. It is graded using a 10x magnifying loupe to detect internal and external flaws. The highest quality is Flawless, followed by 11 other grades.
★ Carat
- The size and weight of a diamond are significant factors in its grading. One carat equals 0.2 grams and is denoted by “Ct”. Larger carat weights increase rarity and value, but the overall grade and price of a diamond are determined by evaluating all 4Cs together.
★ Smaller diamonds are called Melee diamonds and are often more affordable. The total weight of small diamonds is listed as Total Carat, which is generally cheaper than a single diamond of the same weight.
