Arameters In Grading A Diamonds

The 4 Cs :

The important parameters in grading a diamond as undertaken by us are based on the 4 Cs concepts.


The cut of a diamond allows it to make the best use of light. When a diamond is cut correctly, light is reflected from one facet to another, and then dispersed through the top of the stone. If the cut of the diamond is too deep, some light escapes through the opposite side of the pavilion. If the cut is too shallow, light escapes through the pavilion before it can be reflected. Please do not confuse the cut of a diamond with its shape. Diamonds can be cut into a number of shapes, depending on the qualities of the rough stone before it is cut. The most popular diamond shapes are round, marquise, pear, emerald, oval and heart. Whatever the shape, a well-cut diamond is the work of a master diamond cutter. When the cut is right the diamond gives more sparkle.


Diamonds range in colour from faint yellow or brown to very rare pinks, blues, greens, and other colours known as "fancies." The best colour for a diamond is no colour at all. A totally colourless diamond allows light to pass through it easily, resulting in the light being dispersed as the colour of the rainbow. Colours are graded from totally colourless to light yellow. The differences from one grade to the other are very subtle and it takes a trained eye and years of experience to colour grade a diamond.


A diamond's clarity is determined by using a 10-power magnifying glass and a trained eye. Most diamonds contain very tiny impurities known as "inclusions." An inclusion can interfere with the light passing through the diamond. The fewer the inclusion, the more beautiful the diamond will be. Diamonds have the capability of producing more brilliance than any other gemstone. A diamond that is free of inclusions and surface blemishes is very rare and therefore very valuable.

FL - Flawless

No internal or external blemishes when examined under a 10x microscope. Diamonds in this category cannot contain internal graining that is reflective whitish, coloured, or which significantly affects transparency.

IF - Internally Flawless

No internal inclusions but minor surface blemishes which cannot be removed with polishing. That is, characteristics such as surface grain lines, natural and extra facets on the crown. Blemishes that can be removed by minor republishing separate the internally flawless from the flawless grade.

VVS1, VVS2 - Very, Very Slightly Included

Minute inclusions, such as reflective internal graining, difficult to locate using a 10x microscope.

VS1, VS2 - Very Slightly Included

Small inclusions, such as small included crystals which are visible using a 10x microscope.

SI1, SI2 - Slightly Included

Inclusions that can be seen easily under a 10x microscope, and may also be seen with the naked eye using a white background. Inclusions in these diamonds cannot be seen through the crown of the diamond.

Carat - Weight

This is the weight of a diamond measured in carats. One carat is divided into 100 "points," so that a diamond of 75 points weights 75 ct. The carat-weight of a diamond is the easiest measurement to determine. Most importantly, two diamonds can be of equal carat-weight, but their value can differ greatly due to their cut, colour, and clarity.

Quality Check

After the diamonds have been Sortoscopic assorted they are sent to the quality check division, where they are checked by Gemmologist & professionals. Once the diamonds have passed the quality check, they are graded accordingly. Although diamonds wholesale involved processing in large quantities, we make sure that each diamond is thoroughly tested and approved for quality.
