Diamond 4 Cs - Cut, Color, Clarity and Carat Weight
Understanding Quality of Diamonds with the 4C's
While many people have an understanding of different diamond cuts, there is more to ensuring you're buying a quality diamond. Cut, Color, Clarity and Carat weight, known as the 4C's, are the features that come together to determine the value of a diamond. These features also have a subtle effect on the unique beauty of your diamond. With an understanding of the 4C's you'll be ready to pick out your perfect diamond.
Of the 4C's, a diamond's cut has the greatest influence on its fire, sparkle and brilliance, making it, arguably, the most important C. Cut refers not only to the shape of a diamond, but more importantly to its proportions (how the diamond's angles and facets relate to one another), symmetry (the precision of the cut), and polish (the surface of the diamond).
When a diamond is "Ideal-Cut," it means the angles and proportions of the diamond have been cut to produce the ultimate sparkle, fire and brilliance.
The intensity of the white light that is reflected from the diamond's surface and inside
How light scatters and disperses through the diamond to create a rainbow of light
Flashes of white light, or sparkles, that are visible when the diamond moves
Diamonds are weighed in units called carats. A carat is measured in increments called points. One carat is equal to 100 points. Carat weight is the easiest of the 4C's to determine because it is measured on a diamond scale.
Two diamonds of equal weight can have very unequal value depending upon the cut, color and clarity of each.
Often mistaken as size, carat actually measures diamond weight
Save on the cost by looking at a diamond 10 or 15 points less. For example, if you love a 1.2-carat diamond, see what it looks like next to a 1.1-carat diamond of the same quality.
Fancy color diamonds aside, the best, most beautiful color for a diamond is no color at all. Most Jared diamonds are graded "near colorless" - between G and J on the color scale. At a J grade and beyond, the human eye can start to detect a yellow tint.
The D grade at the top of the scale, is considered colorless, rarest and most expensive
Moving down the scale toward H or I lets you buy a diamond that still appears white, but is more common and more affordable
Clarity is the degree to which a diamond is free from flaws, which can hinder light as is passes though your diamond. Like people, diamond have "birthmarks" that vary in size, shape, position, quantity and color. These birthmarks are known as inclusions (internal) and blemishes (external).
The clarity grade is determined based on the size, number, position of, nature and color of the diamond's blemishes
Internal flaws formed deep in the earth during the diamond's growth
External flaws that can result from the cutting process
If you look at an SI2 diamonds and personally can't see the inclusions and/or blemishes without a jeweler's loupe, you can probably accept a lower grade and save on cost without compromising beauty
