Four C's of Diamonds

You’re a seeking the perfect diamond for her engagement ring. Before making your decision, keep in mind the 4Cs.

The worldwide accepted standard for evaluating and categorizing diamonds. Diamond values can vary greatly. Therefore, the monetary value of this gemstone is determined based on these four Cs. However, this system was never intended and falls willfully short of defining beauty.

Trust Your Eyes

No “system”, machine or digital software can or will ever replace the human-eye, the passion in your heart. Like her beauty you will know the diamond for her when you see it.

DEFINING RARITY AND BEAUTY

Gem-quality diamonds are very rare, taking millions of years forming in the nature of the earth. Your diamond’s journey from deep in the earth to the mine to you is long and adventurous.

While the four C’s may help you to identify the quality of a diamond, it is the combination of characteristics which determine a diamond’s true value. Always remember that beauty truly is in the eye of the beholder, which means only you can truly select the perfect most beautifully for you.

COLOR of DIAMONDS

The color of a diamond is measured using the GIA grading scale from D-to-Z. Remember this system is the most widely accepted for grading the yellow body color or lack-there-of. Color graded diamonds are evaluated based on the absence of color, colorless being the rarest.

No yellow, grey, green hues = higher value

Absence of Color

That is why this lack of color is measured by comparisons with masterstones, while viewing in a controlled lighting environment. Which means that regardless of where the diamond is graded it should receive the same grade. These distinctions of color are invisible to the untrained eye and or best done by a trained gemologist.

CLARITY of DIAMONDS

As a diamond’s color is graded based on the absence of color, the diamond’s clarity is graded on inclusions and blemishes or the absence of such.

Internal = Inclusions

External = blemishes

Gem Quality

In gem quality diamonds most inclusions are too small to be be seen by the unaided eye. A trained diamond expert can evaluate the quantity, size, relief, nature, position of these characteristics, and how they affect the appearance of the diamond.

CARAT WEIGHT of DIAMONDS

In addition to color and clarity the carat weight correlates to rarity of the diamond. This happens because larger crystals are rarer and bigger diamonds are much more in demand.

1 Carat = 200 milligrams

1 Point = 0.01 carat = 1/100 of a carat

Diamonds of equal weight are not necessarily the same physical size. It is the proportions and depths that result in different looking sizes with near equal weight combinations.

CUT of DIAMONDS

The Cut is not the shape of the diamond, it is all about light and sparkle that is returned due to a diamond’s faceting. Cut drives the brilliance, fire, and scintillation of each diamond.

Brilliance

The white light combines with the surface and internal structure from within the diamond. As a result returns the pleasant brilliance to the human eye. Creating the Fire are Flashes of color you see in a polished diamond

The slightest movement of the gemstone causes a Scintillation of flashes of the light in all directions.

So a well cut diamond has proportions of its facets, symmetry, relationship of its weight to diameter, girdle edge thickness, and the crystals rarity all come together in just the right way.
