4C DIAMOND

4Cs Education

Origin of the Diamond 4Cs
​Every diamond is a miracle of time and place and chance. Like snowflakes, no two are exactly alike.Until the middle of the twentieth century, there was no agreed-upon standard by which diamonds could be judged. GIA created the first, and now globally accepted standard for describing diamonds: Color, Clarity, Cut, and Carat Weight. Today, the 4Cs of Diamond Quality is the universal method for assessing the quality of any diamond, anywhere in the world.
The creation of the Diamond 4Cs meant two very important things: diamond quality could be communicated in a universal language, and diamond customers could now know exactly what they were about to purchase.

Diamond Color Actually Means Lack of Color

The diamond color evaluation of most gem-quality diamonds 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. GIA's D-to-Z diamond color-grading system measures the degree of colorlessness by comparing a stone under controlled lighting and precise viewing conditions to masterstones stones of established color value.

Diamond Clarity Refers to the Absence of Inclusions and Blemishes

The GIA diamond clarity scale has 6 categories, some of which are divided, for a total of 11 specific grades.
- Flawless (FL)
- Internally Flawless (IF)
- Very, Very Slightly Included (VVS1 and VVS2)
- Very Slightly Included (VS1 and VS2)
- Slightly Included (SI1 and SI2)
- Included (I1, I2, and I3)

A Diamond's Cut Unleashes Its Light

Diamonds are renowned for their ability to transmit light and sparkle so intensely. We often think of a diamond's cut as shape (round, emerald, pear), but a diamond's cut grade is really about how well a diamond's facets interact with light.
​A diamond's cut is crucial to the stone's final beauty and value. And of all the diamond 4Cs, it is the most complex and technically difficult to analyze.

Diamond Carat Weight

Diamond carat weight is the measurement of how much a diamond weighs. A metric "carat" is defined as 200 milligrams.
It's important to remember that a diamond's value is determined using all of the 4Cs, not just carat weight.
