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.Watch 4C Video

Best of the Best | Infini Love Diamond™ CUT
Hearts and Arrows and Octagonal Star pattern
“Infini Love Diamond™Cut”is the most immaculate Cut in Chow Sang Sang’s specifications, a standard that is more rigorous than any of those in the jewellery industry. The Excellent among Excellent grades attained in a diamond’s Proportions, Symmetry and Polish guarantee the gleam of full brilliance and fire. The unique Hearts and Arrows and Octagonal Star pattern is the epitome of precise cutting, with its exact symmetry and balance being the benchmark of premier radiance.
We are passionate about symmetry. For our Infini Love Diamonds, we insist on the best craftsmanship to maxmise fire and brilliance.
Every facet of an Infini Love Diamond is impeccably polished and flat to beautifully reflect light and enhance brilliance.
Our master craftsmen translate a standard that is more rigorous than any of those* in the jewellery industry into meticulously-cut Infini Love Diamonds™ of 57 facets with the consideration of the diamond’s proportions and symmetry.*GIA 2009 Cut Grade Estimation Tables for Standard Round Brilliant Cut Diamonds
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.
Still offer exceptional brilliance and fire like the Excellent diamonds, Very Good ones are slightly flawed.
One grade lower than Very Good, Good diamonds showcase relatively dimmer brilliance, fire, and sparkle.
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.
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.
Very, Very Slightly Included
Very Slightly Included
No inclusions and no blemishes visible under 10x magnification
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.
Very Light Colour
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.
Diamond carat weight measures a diamond’s apparent size. One caret equals to 100 pointers, weighing 0.20 gram. Chow Sang Sang offers diamonds in a wide range of sizes to suit your personal needs.

This is the bottom portion of the diamond from the girdle to the culet.
The culet is bottom tip of the diamond.
Depth is the height of the diamond from the table to the culet.
