THE WORLD'S MOST PERFECTLY CUT DIAMOND ®

What Are The 4Cs?

The 4Cs are cut, color, clarity, and carat weight. Together they contribute to the overall beauty and value of a diamond.

What are the 4Cs?

At Hearts On Fire, we pay close attention to each of the 4Cs, ensuring bright, beautiful, sparkling diamonds every single time. Of the 4Cs, cut- its proportion and symmetry- is the most important factor in determining a diamond's beauty, value, and light performance.

Which of the 4Cs matter most?

Diamond cut is the single most important of the 4Cs when it comes to the physical beauty of a diamond. Why? Because a diamond’s cut determines how much it sparkles. 

The number of facets, the angle of the facets, and the symmetry and alignment of the shape will affect how the diamond returns light. And the goal of diamond cut should always be optimal light return. However, because diamond crystals are among the most valuable items on the planet, most diamonds cut in the industry today are still cut for weight retention at the expense of beauty.  We cut each and every one of our diamonds for optimal light return at Hearts On Fire. 

And as a result, Hearts On Fire diamonds always receive an Ideal rating from the American Gem Society (AGS). An Ideal rating from the AGS is rare—in fact, only about 3-5% of the world’s cut diamonds are cut to ideal proportions.  Hearts On Fire diamonds are the truly the best-of-the-best.

Achieving an Ideal cut involves both art and science, and neither should be sacrificed. For example, some diamond cutters tailor the cut so the carat weight stays above 1.0 carats. But this isn’t always a good thing.

For each individual diamond, there are specific proportions that will make the diamond sparkle at its best, and it is far better to have an Ideal-cut diamond that is 0.90 carats than a poorly cut diamond that is 1.00 or 1.10 carats.  A good cut will result in a better sparkle. That’s why cut is the most important of the 4Cs—if a diamond is poorly cut, no clarity grating, color grading, or carat weight will make up for it. The diamond will look dull and glassy. When a diamond is cut to the proper proportions and symmetry, it will return light out of its top. If a diamond cut is too deep, the light will leak out the side, and if a diamond cut is too shallow, the light will escape out the bottom.  Ultimately, the precision of the cut affects the value of a diamond by 50% or more. Next to carat weight in a larger diamond, it is the most important value factor for a diamond. 

When you look at a diamond, all you’re really seeing is its sparkle. And that’s a result of expert craftsmanship.
