The Four C's:

The diamond’s cut grade is the most important of the 4 C’s, it deals with how well a diamond’s facets, table size, correct crown and pavilion angles, and total depth are cut. An extremely high level of accuracy in the cutting will allow how well the diamond interior interacts with light to create the maximum light returned of brilliance, fire, and sparkle to your eye. This is why diamonds are renowned for their ability to transmit light when this precise artistry and workmanship are performed to the correct percentages to fashion a stone, its proportions, symmetry, and polish will deliver the magnificent return of light only possible in a diamond. The proportions deal with the diamond’s correct cutting of the crown and pavilion angles, right table spread and total depth percentages in relation to the diamond’s diameter.

A well cut Ideal or Premium cut diamond has a range of 53% to 61% table spread and 59% to 62% total depth in relation to the diamond’s diameter at the girdle. The symmetry basically deals with how the diamond’s facets are in alignment with each other so that they are symmetrically arranged and evenly placed around the surface of a diamond’s shape. The polish refers to the degree of smoothness that each faceted surface on a diamond is polished down too. Quality of a diamond’s cut grade can range from Ideal, Excellent, Very Good, Good and finally to Fair or Poor. See the pictures that show the Ideal and Premium cut proportions and what bad symmetry in a diamond looks like.


The diamond’s color is the next C in importance. The diamond color evaluation is based on the absence of color.
A chemically pure and structurally perfect diamond has no hue, like a drop of pure water, and consequently, a higher value. Color ranges from D-to-Z in a diamond color-grading system, it measures the degree of colorlessness to begin with, to the amount of nitrogen in the diamond that colors a diamond from faint to light yellows. Many of these diamond color distinctions are so subtle that they are invisible to the untrained eye; however, these distinctions make a very big difference in a diamond’s quality and price.diamond color scale

The third C: clarity, refers to the absence of inclusions in a diamond interior and blemishes on a diamond’s surface. Natural diamonds are the result of carbon exposed to tremendous heat and pressure deep in the earth. This process can result in a variety of internal characteristics called ‘inclusions’ and external characteristics called ‘blemishes.’ The diamond clarity scale has 6 categories, some of which are divided, for a total of 12 specific grades. It ranges from Flawless (FL) no inclusions and no blemishes visible under 10x magnification, Internally Flawless (IF) no inclusions visible under 10x magnification, Very, Very Slightly Included (VVS1 and VVS2) Inclusions so slight they are difficult to see under 10x magnification, Very Slightly Included (VS1 and VS2) Inclusions are observed with effort under 10x magnification, but can be characterized as minor, Slightly Included (SI1, SI2, and SI3) inclusions are  noticeable under 10x magnification and Included (I1, I2, and I3) inclusions are very obvious under 10x magnification which may affect transparency and brilliance.

Diamond carat weight is the measurement of how much a diamond weighs. A metric “carat” is defined as 200 milligrams. Each carat can be subdivided into 100 ‘points.’ This allows very precise measurements to the hundredth decimal place. A jeweler may describe the weight of a diamond below one carat by its ‘points’ alone. For instance, the jeweler may refer to a diamond that weighs 0.25 carats as a ‘twenty-five pointer.’ Diamond weights greater than one carat are expressed in carats and decimals. A 1.08 carat stone would be described as ‘one point oh eight carats.’

For centuries, diamonds have been desired as symbols of magic, passion and success. These fascinating gems hold a mystery like no other material object. Billions of years in the making, they hold a deep romantic mystery that lies within the heart of every gemstone.  The name diamond comes from the Greek “adamas” meaning “invincible”.  Originally thought to be “Tears of the Gods,” diamonds were believed to hold mysterious qualities and possess supernatural powers.Every diamond’s story begins billions of years before it arrives in the jeweler’s showcase. Diamonds start out as molten magma 100 miles below the surface of the Earth. In a few cases, tremendous temperatures, pressure, and time compress the magma and crystallize it, forming diamonds. Sometimes, the pressure forces those diamonds toward the surface of the Earth. Only a very few make it to the surface; but many more can be found in mines hundreds of feet deep. The largest mines are located in Botswana, Russia, and Canada, but diamonds have been found in many areas throughout the world including the United States.

To produce one carat of diamonds, miners sift through approximately 200-250 tons of ore. The average size of the diamond coming out of a mine is .10 carats, and even then, only 20% of mined diamonds are gem quality.

Those diamonds that are deemed gem quality are then sorted based on size, shape, quality, and color. The sorted gems are sold at an invitation-only sale held only 10 times each year. From there, diamonds undergo an exhaustive cutting and shaping process before being placed into a setting. And much of this process is still done by hand by a few master gem cutters.

The Diamond’s Fingerprint
It’s a fact. Every diamond is different. Their attributes combine in countless ways to create each gemstone’s unique “fingerprint.” But these attributes also determine a diamond’s value, so you’ll have to decide which factors are most important to you to find the diamond that’s perfect for both you and your budget.
