Understand Diamonds
The art of brilliance
Of the 4Cs, cut has the greatest effect on brightness — and is the only factor that can be influenced by the craftsman. If the cut is too shallow or too deep, light will not be properly reflected, diminishing brightness. When the facets are ideally proportioned, light is reflected to dazzling effect. Conversely, even a flawless diamond that is poorly cut will be dull.

Cut+ is the only one of the 4Cs that is influenced by a skilled craftsman. 99% of Chow Sang Sang Handpicks achieved the rating of “Very Good” or above.

Excellent
Regarded as the highest rating in the jewellery industry,
diamonds of the Excellent grade represent their ideal proportions,
symmetry, and polish to radiate with
magnificent sparkle.
Brilliance
Very Good
Still offer exceptional brilliance and fire like the
Excellent diamonds, Very Good ones are slightly flawed.
Brilliance
Good
One grade lower than Very Good, Good diamonds showcase
relatively dimmer brilliance, fire, and sparkle.
Brilliance
Fair
Fair diamonds are less satisfactory choices as they offer little
brilliance, since the cut is imbalanced and imprecise, making light
easily exits through the bottom and
sides of the diamonds.
Brilliance
Poor
Poor diamonds are unsatisfactory ones as they yield nearly no
spark since the cut is disproportioned and entering light escapes from
the sides and bottom of the diamonds.
Clarity measures the flawlessness of a diamond; the fewer internal inclusions, cracks, or other non-crystallized carbon materials, the lower the chance of light refractions being blocked, and thus the brighter the brilliance. Chow Sang Sang assesses the depths of inclusions with extreme precision, refusing to pick diamonds that have inclusions close to the surface of the crown. Chow Sang Sang Handpicks is also extraordinarily strict with clarity superiority – mostly only SI2 grade or above are selected; Infini Love Diamonds only belong to VS2 grade or above.
Flawless/Internally Flawless
FL：
No inclusions and no blemishes visible under 10x magnification
IF：
No internal inclusions visible under 10x magnification, but with barely visible external flaws
Inclusions so slight they are difficult for a skilled grader to see under 10x magnification
Minor inclusions are observed with effort under 10x magnification
Inclusions are easier to be noticeable under 10x magnification or naked eye.
Inclusions are denser and more obvious under 10x magnification or naked eye, which may affect diamonds’ transparency and brilliance.
Diamonds are naturally coloured; the closer white diamonds are to being transparent, the more precious they are since their value is directly proportional to their colourlessness. Diamonds are classified on an internationally recognized scale from colourless (graded as D) to saturated (graded as Z) under the naked eye. Grades D to J are colourless or nearly colourless, among which Chow Sang Sang only chooses fine diamonds of grades D to K, and refuses to use diamonds of milky or brownish colours.
D-F Colourless
Colour of the highest grade, D stands for ultimate colourlessness. E-F are also colourless, with differences only visible under the vigilant eyes of experts.
G-H diamonds are nearly colourless, with minimal colour only visible when the table is tilted downward. I-J diamonds are also nearly colourless, and very slight difference is noticeable only when compared.
From K colour onward, these diamonds possess visible yellow tint. For L-M colours, they mean slight yellow coloration that can be noted by the naked eye even with no special expertise.
From N colour onward, these diamonds possess notable light yellow tint. Only very few Chow Sang Sang Handpicks belong to this colour category.
From S colour to Z colour, these diamonds possess visible light yellow tint. Only very few Chow Sang Sang Handpicks belong to this colour category.

Table
The table is the diamond’s largest facet.
Crown
This is the top portion of the diamond from the girdle to the table.
Girdle
Found between the crown and the pavilion, the girdle determines the circumference of the diamond.
Diameter
The width of the diamond measured at the girdle.
Pavilion
This is the bottom portion of the diamond from the girdle to the culet.
Culet
The culet is bottom tip of the diamond.
Depth
Depth is the height of the diamond from the table to the culet.
Brightness
Fire
Scintillation
Brightness
A measure of the white light reflected internally and externally by the diamond. A well-cut diamond has greater brightness.
Fire
The rainbow-coloured light that emanates from a diamond, caused by white light being dispersed into its spectral colours.
Scintillation
The sparkle that a diamond emits when it or the light source is moved.
