4 C’s Of Diamond

Diamonds are renowned for their ability to transmit light and sparkle so intensely. It is often misunderstood of a diamond’s cut as shape (round, heart, oval, marquise, pear), but what diamond cut actually mean is how well a diamond’s facets interact with light.

Cut affects on following aspects of a diamond

• Brightness: Internal and external white light reflected from a diamond
• Fire: The scattering of white light into all the colors of the rainbow
• Scintillation: The amount of sparkle a diamond produces, and the pattern of light and dark areas caused by reflections within the diamond

Most diamonds of gem quality used in jewelry vary in shade from completely colorless down to a visible yellow or brown tint.

The rarest and most expensive are diamonds in the colorless range graded D,E and F on a scale that descends to Z. Diamonds with more color than Z, or in other shades such as orange, pink, blue, etc. are classified as “Fancy Colored Diamonds”

There are two types of clarity characteristics: inclusions and blemishes. In order to grade the clarity of a diamond, it is necessary to observe the number and nature of external and internal characteristics of the stone, as well as their size and position. The difference is based on their locations: inclusions are enclosed within a diamond, while blemishes are external characteristics.

The weight or size of a diamond is measured in carats (ct.).

One carat weighs 1/5 of a gram and is divided into 100 points, so a diamond weighing 1.07 ct. is referred to as “one carat and seven points.”

For example,

• 0.75 carat = 75 points
• 1/2 carat = 50 points
• 1/4 carat = 25 points
