How Important is the Cutting Grade of a Diamond in a Diamond Jewelry?

The cut is an important factor in determining a diamond’s quality. It is one of the 4Cs used to evaluate diamonds, along with color, clarity, and carat weight. It has an impact on the diamond’s ability to dazzle and shine. Pertaining to identifying the quality of a diamond’s cutting, the Diamonds Buying Guide of Rare Carat will give you insights on how to evaluate a diamond upon purchase. Diamonds’ cut grades are based on the following attributes:

Diamond Cut Grade Basis

Proportion

The precise dimensions and angles used in the cutting procedure are referred to as the diamond’s proportions. A diamond’s percentage can have an influence on how light is refracted through it, which will alter how sparkly and brilliant it appears. If the diamond has an equal set of facets and cutting slopes, it gives a luxurious and fine luster.

Symmetry

The regularity of a diamond’s facets and the stone’s general form are both examples of symmetry. Perfect symmetry is seen as a sign of great quality in diamonds. Diamonds have ideal symmetry which have almost equal height of crown and culet.

Polish

The smoothness and general surface of a diamond are referred to as its polish. A diamond that has been polished to a high degree will reflect and absorb light more successfully. This makes the diamond’s surface brighter and glossier.

Light Performance

The way a diamond reflects and refracts light is referred to as “light performance”. a diamond is said to have exceptional light performance if it reflects light to the eye with the most brightness and fire possible.

Jewelers often utilize the GIA (Gemological Institute of America) grading system when assessing a diamond’s cut grade. Excellent is the highest cut quality, while “poor” is the lowest, on a scale from excellent to poor.

Diamonds Cut Grade

The top cut rating of “excellent” is given to diamonds that have superb proportions, symmetry, polish, and light performance. A grade of “very good” or “good” may be assigned to diamonds with somewhat below excellent qualities. A diamond is given a “fair” or “poor” rating if it has obvious discrepancies in its dimensions, symmetry, polish, or light performance. It is a fine knowledge to understand more about diamonds 4Cs, especially their cut to allow yourself to confidently familiarize how to assess a diamond seller’s promise for quality and authentic diamonds.

Excellent Cut

These diamonds are cut to ideal proportions making them reflect and absorb light in ideal ways. Here, the design and purpose of the diamond are achieved where it gives the most preferred amount of light and sparkle. They have a very equal set of facets and cut edges that arrives at the most scientific light collisions. 

Very Good Cut

These diamonds have cutting proportions that have an almost similar quality to ideal cuts. The difference is hard to identify but the amount of sparkle and light refraction and reflection it gives may still seem different than the excellent cut quality. 

Good Cut

Diamonds of Good cut quality may not be able to sparkle and create a lustrous glimmer compared to an excellent or very good cut. Its cutting edges may have a higher number of discrepancies and will not give one of the most eye-catching glimmers at any angle. As these diamonds have unequal facets, they could not gather an ample amount of light to reflect out. Hence, this cut can still stand to be elegant and opulent-looking when it has a higher quality than all other diamond 4Cs profiles. 

Fair Cut

Fairly cut diamonds may not have cut edges that are sharp enough to catch the light and reflect it. Moreover, it may also include some discrepancies in the equality of the sharpness of the edges which could not be continuous making the light not go through the intersecting edge lines to give ample number of sparks. 

Poor Cut

Poor-cut diamonds have the conditions of a fair-cut diamond’s edges while not having smoothly polished. Hence, its facets may not have equal polishing making the light that gets into the diamond’s surface get diffused on the other side of the diamond.
