Diamond Polish, Symmetry & Cut Grade
A diamond's polish and symmetry are critical to the quality of its cut. For maximum brilliance, every facet of a diamond should be professionally polished after the cutting process. A high quality polish will leave little to no scratches and marks, while a poor polish can result in imperfections on the surface of the diamond, which can lower its value.
A symmetrical diamond will have well-balanced, properly aligned facets, resulting in a high level of fire and brilliance. If the facets are not symmetrical or not optimally shaped, they'll display less sparkle.
A gemologist assigns a cut grade as a means of measuring a diamond's proportions, craftsmanship, quality of polish, and light reflecting properties.
A diamond with a high quality cut grade will exude a large amount of brilliance and fire. A diamond's ratings for symmetry, polish, and cut grade may vary based on which Gemological Laboratory is evaluating it, as each agency uses a different scale.

Not all certification labs offer a “Cut” on their certificates especially when it comes to fancy shaped diamonds (non-round cuts). Understanding that this is a crucial factor when purchasing a diamond, Brilliance gives its own rating on a diamond called a “Diamond Make or Cut”. Combining all the different factors that are important in a diamond cut, “Make” is a term used to describe the overall appearance of a diamond and is based on a combined analysis of its shape, cut, proportions, polish, symmetry, and light reflecting properties. The “Make” of a diamond directly impacts its brilliance and beauty; if a diamond is designed, cut, and finished properly, it will have a much more desirable appearance, even when compared to diamonds of higher color and clarity grades. Brilliance gemologists use this term to provide our customers with a general assessment of cut to simplify shopping for the perfect loose diamond.
We use the following designations to rate the 'Make' or Cut of our diamonds:
Super Ideal Make: Our highest quality cut, this Make will reflect the maximum amount of light, exhibiting unrivaled brilliance and fire. 'Super Ideal' Make diamonds are extremely rare; only 5% of our loose diamond assortment receives this grade.
Ideal Make: This indicates a superior level of craftsmanship, emitting the most brilliance and light. Consumers seeking premium cuts prefer 'Ideal' Make diamonds.
Excellent Make: Cut to a high-quality polish and symmetry, this diamond Make will reflect all light as brilliance and fire.
Very Good Make: This grade of diamond reflects nearly all light that enters. Less expensive than an 'Excellent' Make, it still displays a good amount of brilliance and sparkle.
Good Make: An economical choice for the diamond shopper on a limited budget, a 'Good' Make reflects most light that enters it, offering beauty at an attractive value.
