As a jewelry retailer, it is essential that you strike the ideal balance between delivering what your clientele wants and managing costs in order to compete - and thrive - in the competitive landscape. The best way to do this is to educate yourself about the many facets (pun intended!) of diamond buying. 

Your customers are coming in equipped with information when they are looking to purchase a piece; it is imperative that you do the same when it comes to purchasing the diamonds with which you will wow them.

Starting with the Four C’s - cut, clarity, color, and carat  - make sense. Many experts agree that cut is the most critical of these, and it can have the biggest impact on your business. By far, the most popular cut on the market is round brilliant, accounting for about 70% of all diamond sales. But what does “brilliant diamond” mean? 

What Does Brilliant Diamond Mean?

As you know, diamonds don’t emerge from mines in showroom shape. Instead, they are “rough.” That is, they appear like a dull stone instead of a sparkling stunner. They must go through the cutting process in order to reveal their true beauty - and in order to impart the characteristics that consumers value so highly (e.g. sparkle, shine, brilliance, etc.).

That leads to the next question then: how are diamonds cut to look brilliant? First, let’s clarify: “brilliant” is a type of cut. It features 58 facets, or 57 facets depending on if it has a culet, and 33 of these are on the crown, and 25 are on the pavilion. These flat surfaces are what create the interplay of light that we associate with diamonds. In the hands of a master cutter, a brilliant diamond has maximum:

  • Brightness/Brilliance: the white light reflected from the facets
  • Fire: the colored reflections created when the white light is dispersed
  • Scintillation: the sparkle of a diamond that results from the interplay of the reflections when the stone is in motion

The Gemological Institute of America (GIA) looks at these factors when they grade a diamond. They are also looking at the proportions, symmetry, and polish of the facets, the appearance when viewed from the top, and the craftsmanship/workmanship involved. This is really what marks an outstanding brilliant cut. It’s not so much the diamond’s inherent qualities; rather, it is the beauty that a skilled cutter can bring out.

Are Brilliant-Cut Diamonds More Valuable?

With diamonds, it’s not so much the rarity that influences cost but the quality. As always, value depends on a variety of factors. Cut quality is, arguably, the most important. But when it comes to the price you will pay for a large brilliant, you will also need to factor in the other three C’s.

Round brilliant cuts are the most expensive diamonds, though, because of the cutting process. In order to create a brilliant, the cutter must waste a relatively high amount of rough stone. A large rough stone may yield a much smaller finished diamond. With fancy cuts, like pear or oval, there is much less waste. The cut quality, however, is not as sharp, as dazzling, as well… brilliant… as brilliant cuts. 

The benefit of opting for an Excellent or Very Good cut grade when purchasing a round brilliant cut is that you can compromise a bit on clarity, color, and carat weight. How much you flex is up to you, but an Excellent cut can make up for a lower grade in clarity, for example. Flaws will be minimized while sought-after attributes (e.g. sparkle and shine) will be maximized.
