Understanding the Diamond Cut Round Brilliant: A Guide for Jewelry Professionals

As a jewelry professional, knowing diamonds and what determines their value is key in offering the best products to your clients. Among the most crucial elements is the diamond cut which greatly influences the attractiveness and quality of the diamonds you will sell. This article will concentrate on the round brilliant diamond cut, its features, and how it influences the overall value of a diamond. We also will discuss various diamond cuts, the highest diamond quality, and certified diamonds.


Why Round Brilliant Diamond Cut is So Popular

Round cut diamonds are super popular - they make up about 75% of all diamonds sold. People love them because they let in a lot of light, which really makes the diamond sparkle. The round brilliant cut is a special type of round cut that was developed in the early 1900s and is now the go-to standard for round cuts. The way it's cut makes the diamond shine its brightest, which is why a lot of people pick it for engagement rings and fancy jewelry.


Understanding Diamond Cut and Clarity

The cut of a diamond greatly contributes to its value. A good polish makes a diamond sparkle more and catches everyone’s eyes. This is because the cut is what determines how well the diamond can refract light and that is what gives the diamond that sparkle. The “diamond cut clarity” only concerns symmetry and cut quality. When a diamond is poorly-cut, it doesn’t reflect light in the correct way, and as a result, it will not look as sparkly or be as valuable.


Different Diamond Cut

There are lots of ways to cut a diamond, and each style changes how the diamond catches light:

Princess Cut: The diamonds are square with pointy corners. Right after that, they are the ones which are admired by most people for their contemporary appearance. They shine almost as much as round well cut diamonds.

Emerald Cut: This one has a rectangular shape with superimposed facets. It's not as brilliant as some other cuts, but it has a classic, old-time flawlessness and really highlights the diamond's purity.

Asscher Cut: It looks like a square version of emerald cut diamond but more depth so it is extra sparkly. It was a huge success during the Art Deco period and is getting popular again.

Cushion Cut: This style looks like a square with rounded corners (kind of pillows is the reason for the name). It's around for two centuries and the most trendy until the early 20th century. It has a classic romantic look, minus the sparkle.

Marquise Cut: It is an oval shape with pointed ends- which makes the diamond look bigger, and can even make the figure slender.

Pear Cut: This one has a combination of round and marquise shapes so it's a teardrop. It's very flashy and also makes one's fingers look slimmer.

Oval Cut: Exactly as the name implies, it's an oval-shaped diamond. It's almost as sparkling as spherical diamonds but has a different shape. The extended design lengthens and reduces the fingers, as well.

Radiant Cut: This one has a nice blend of round diamonds which sparkles and the trendy shapes like emerald or princess cuts. It has 70 facets, it really shows off the stone color.

Each and every diamond cut has its own singular look and worth which in turn determines how the diamond looks and feels.


The Importance of Certified Diamonds:

Finally, you need to be sure that the diamonds that you sell or use in your designs are real. Such is done by a diamond certificate. It is pretty much like a report card that will indicate the diamond’s grades according to color, clarity, cut, carat weight and the like.
