Carat indicates a diamond’s weight. A single carat, the common unit of measurement for diamonds, is around 0.2 grams. You may also hear the weight of a diamond referred to in points. Once carat equals a 100 points, so a 75 point diamond is equal to 0.75 carats. Because they are uncommon, larger diamonds have much higher value per carat, so the cost of a diamond rises exponentially to its size.
While cut includes shape, in terms of the 4Cs it refers to the proportions of the cut. A diamond’s cut grade is an straight measure of a diamond’s light performance, or the quantity of sparkle the diamond has.
A diamonds overall proportions, as well as the size and situation of its facets, make up the cut. The firmness and harmony of these can greatly affect how the stone catches light and reflects it back to the eye. When a diamond is cut with the correct proportions, light gets into the diamond and is brought back through the top of the diamond. If a diamond is too shallow, light will fadeout from the bottom of the stone. If it is cut too deep, light will fade out through the side.
Research has been conducted in the past to find the ideal proportions of a diamond’s cut so that it has the highest amount of sparkle. if its cut falls within these parameters, it is treated as an ideal cut.
Diamonds with beautiful proportions, symmetry and polish increase their interaction with light and have increased brilliance, dispersion, and glare.
The diamond’s clarity is measured by the presence or absence of visible flaws. Tiny surface blemishes or internal inclusions, even those seen only under magnification, can change the brilliance of the diamond and hence affect its worth. Clarity levels begin with flawless (FL, IF), followed by very, very slight (VVS1, VVS2), very slight (VS1, VS2), slightly included (SI1,SI2), and included (I1,I2 and I3).
A factor that determines the worth of a diamond is its color. Excluding fancy-colorer diamonds. the most valuable diamonds are those with the least color. Although it is thought of gem quality diamonds as colorless, completely colorless diamonds are a rarity. The diamond color scale ranges from D (colorless) to Z (light yellow or brown). The diamond’s color is obtained by a manual process of comparing the diamond to a master set. Each letter grade indicates a range of color and is a measurement of how noticeable an specific color is.
When diamond emerge with traces of other various minerals, rare and beautiful colors can result. These colors range from blue and brilliant yellow to red, brown, pale green, pink, and violet. Because of how rare they are, coloured diamonds are highly desirable and typically more valuable.
