Which is the most important of the Diamond 4Cs?

In today’s post we will have a closer look at the diamond cut and the diamond carat weight. Both belong to the so-called diamond 4Cs and are very essential factors in determining the quality of the diamond.

But let’s take a look at it one after the other!

The Diamond Cut

The third C is cut. The GIA cut scale is used for round brilliant cut diamonds and consists of five grades ranging from excellent to poor. You may think of cut as the shape of the diamond, like square cut or round. However, there is much more to cut than the basic shape.

The GIA Diamond Cut Scale

How a diamond is cut and polished, directly affects the amount of sparkle and brilliance that comes off the stone when it interacts with light.

How light strikes the surface, how much enters the diamond, and how and in what form light returns to your eye. A polished diamond’s proportions affect its light performance, which in turn affects its beauty and overall appeal.

Our diamond is placed in a highly-precise measuring device that rotates the stone 360 degrees to optically capture hundreds of measurements in facet angles. Enough to generate a 3D model of the actual diamond. Since there is no single set of proportions that define a well-cut diamond, a cut grade needs to be determined by factoring in a range of parameters.

After 15 years of research, GIA scientists developed a comprehensive system that factors the diamond’s proportions as well as its culet size, girdle thickness, polish, and symmetry descriptions, and generates a GIA cut grade.

Our diamond received a cut grade of excellent.

Diamond Carat Weight

The fourth C is carat weight. One carat equals 200 milligrams, or one-fifth of a gram in weight. Larger diamonds are more rare than smaller diamonds. So all other factors being equal, a single one carat stone will be worth more than four quarter carat stones put together. However, the value of a diamond is determined by considering all Four C’s, so bigger is not always better.

At the GIA lab, our diamond is placed in a sealed chamber and weighed on an extremely precise electronic scale to the fifth decimal place. The weight is then rounded to the second decimal place. Our diamond weighs 2.07 carats.

Our diamond’s Four C’s, along with the wealth of additional information appears on its GIA grading report:

GIA grading report

A GIA report is the most technologically advanced diamond evaluation possible. It provides a unique blueprint of a diamond’s attributes and a permanent record of its quality. And GIA’s online report check provides an additional level of assurance.

It allows you to quickly and conveniently confirm that the information you received matches the original grading archived in GIA’s database.

As an added security feature, diamonds graded at GIA can be microscopically inscribed along the girdle with their unique GIA report number, a personal message, or even a logo. Laser inscription allows you to easily identify your diamond and provides an indisputable link to your diamond’s grading report.

Whether you’re celebrating the past or getting ready to leap into the future, there is no better way to commemorate this important moment in time than with a diamond – a symbol of timelessness itself. The act of choosing your diamond should be exciting and enjoyable.

Just keep all the Four C’s in mind: color, clarity, cut, and carat weight. And be sure to always ask your jeweler for a GIA report, your ultimate assurance of your diamond’s quality. What you’ve chosen is rare, unique, and breathtakingly beautiful. You’ve chosen a diamond, and you’ve chosen well.

Because a GIA grading report is the difference between wondering and knowing we recommend to buy diamonds associated with a GIA grading report.

A diamond grading report by AGS is also an absolutely viable option if you want to go for a high quality diamond!
