GIA
GIA has calculated the cut result for 38.5 million proportion sets based on the assessments of seven components. The first three - Brightness, Fire and Scintillation are appearance based aspects. The remaining four - Weight Ratio, Durability, Symmetry are related to a diamond's design and craftsmanship.
In GIA diamond cut grading system, each component was assessed individually, taking into account the relative importance of that component in the overall cut quality of a round diamond and the ability of an average, experienced observer to consistently see the differences in cut quality based on these components.
J. B. And Brothers is dedicated to achieve the cutting-edge "GIA cut grading system" for its diamonds and ensure the best cut quality.
AGSL
The AGS "Ideal Cut" Grading system is based on the 3-D model that evaluates every facet of the diamond through the triple parameters of Light Performance, Proportion Factors and Finish. Light Performance includes Brightness, Dispersion (Fire), Leakage and Contrast. Proportion Factors include Girdle Thickness, Culet Size, Weight Ratio, Durability and Tilt. Finish includes Polish and Symmetry.
J. B. And Brothers endeavours to achieve this "Ideal Cut" for its diamonds as per the AGS Grading system.

IGI
Colour, Shape, Clarity and Carat Weight determine the rarity and value of a diamond, while the Cut determines its beauty. Without any cutting, bruting, faceting or polishing, a rough diamond might go unnoticed in a pile of rocks. It is the diamond's unique symphony of durability, rarity, potential beauty brought out by the "Cut" that makes it so precious and invaluable. "An Ideal Cut" diamond is a grade which is above excellent. Such diamonds have a perfect balance of Brilliance, Dispersion and Scintillation.
It is a constant endeavour at J. B. And Brothers to master this "Ideal Cut", bringing beautiful and perfectly balanced diamonds to our customers.
Hearts & Arrows
A "Hearts & Arrows" cut diamond is the finest cut diamond. Extremely rare, its sentimental charm and mystery are unparalleled. When the bezel, star, upper girdle, lower girdle and pavilion main facets of a diamond are aligned precisely 180 degrees opposite of each other, the perfect "H&A" pattern emerges.
The clinical precision facet alignment to produce the "ideal cut" involves extensive labour and sacrifice of precious diamond material, as even the slightest asymmetric cut results in uneven or incomplete display of the pattern. The "Hearts & Arrows" optical effect is the unique diamond with a perfect balance of Brilliance, Dispersion and Scintillation and is priced at a premium.
J. B. And Brothers has constantly endeavoured to master the perfect "H&A" diamond and continues to do so.
