Understanding Diamond Value
Diamonds are some of the world's most precious and sought-after gemstones, with their value determined by four criteria – carat weight, cut, clarity and color.
Carat Weight
A diamond's carat weight refers to both its size and weight; one carat equals 0.2 grams and the larger the diamond is, the higher its carat weight is. However, its value does not solely depend on carat weight; other aspects like cut, clarity and color also play a pivotal role in establishing its price.
Cut
The cut of a diamond refers to its proportions, symmetry, and polish. A well-cut diamond reflects light better, making it more brilliant and sparkly. The cut also affects the diamond's overall shape, such as round, princess, emerald, and more.
Clarity
The clarity of a diamond refers to the number and size of inclusions or blemishes within the stone. Inclusions are internal flaws, while blemishes are external flaws. The fewer inclusions and blemishes a diamond has, the higher its clarity grade and value.
Color
The color of a diamond refers to its hue, saturation, and tone. The most valuable diamonds are colorless, with a grading scale that ranges from D (colorless) to Z (light yellow or brown). The closer a diamond is to being colorless, the higher its value.
Overall, a combination of the 4Cs determines the value of a diamond. A high-quality diamond with an excellent cut, high clarity, and colorless color can be worth millions of dollars, as evidenced by the world's most expensive diamonds.
