Understanding Lab Grown Diamond Brilliance and Precision
Whether mined or lab produced diamonds, their brilliance and quality boil down to the quality of their cut. How precisely a diamond is cut, how much balance there is in its facets, and how light passes through it, are all nuances that impact its brilliance and performance.
In this blog, we dissect all the factors that affect a lab grown diamond’s brilliance.
What is ‘diamond cut’?
Cut is one of the 4 Cs of diamonds. Rough cultured diamonds have to be cut to get a desired shape and brilliance. Cut refers to the shaping of a diamond for polishing. It also refers to the symmetry, proportioning and polish of a diamond. Cut affects a diamond’s performance. There are different types of diamond cuts, for instance, brilliant cut diamond, round cut, oval cut, emerald cut, etc. When diamonds are cut to precision, light is able to enter it precisely and is reflected in a way that makes the diamond sparkle and illuminate brilliance.
Why is diamond cut important?
A lab produced diamond’s cut is important because the angles of the pavilion, the measurements of its different parts, and facets all contribute to its appearance and performance. The cut can help determine the diamond’s brightness, scintillation, and fire. The cut of the diamond also influences its price and value. The best lab grown diamonds have a perfect, ideal cut, which appreciates its value and pricing.
Diamond cut proportions and effects on diamond performance
The proportions of diamond cut affect how light travels and reflects in a diamond. Let’s look at the ideal proportions and their effect on cultured diamonds.
-
Table size: The length and width of a diamond’s top surface area. The maximum the table size, the lighter dispersion and reflection possible.
-
Star length: This refers to the length of the angled facets adjacent to the table.
-
Girdle thickness: Height of the girdle, that’s the belt that divides the crown from the pavilion. A thin to slightly thick proportion is considered ideal.
-
Culet: Bottom tip of a lab grown diamond.
Cut grades and their meaning in reference to diamond quality
-
Ideal cut: offers maximum brilliance and fire, reflects all light that enters the diamond. The best lab grown diamonds would have an ideal cut.
-
Excellent cut: offers excellent sparkle and brilliance, reflects most light that enters the diamond.
-
Very good cut: offers sparkle and brilliance and reflects a high percentage of light and is less expensive than excellent cut.
-
Good cut: offers good sparkle and brilliance and reflects most of the light that enters the lab grown diamond.
-
Fair cut: may lack sparkle and brilliance as it reflects some light.
-
Poor cut: dull in appearance and reflects minimal light.
Summing up
When assessing the best lab grown diamonds, you must take into account the above factors relating to diamond cut and its impact on its appearance. The next time you want to buy lab grown diamonds, make an informed decision by identifying these features before you make a purchase.
