DIAMOND GUIDE (4C's)

1. CUT

The most important of the four Cs is cut. The way a diamond is cut affects its brilliance, sparkle, and fire, as well as its overall worth and beauty. The diamond is purposeless without these attributes, regardless of carat weight, colour, or clarity. Cut and Shape are sometimes confused, but they are not the same thing; cut is concerned with symmetry and proportion, whereas shape is concerned with the contour and form of the diamond.

What Impacts Diamond Cut Quality?

The only one of the four C’s that is affected by human hands is Cut. Two diamonds with the same clarity, colour, and carat weight can be distinguished by their cut. Simply said, a diamond's cut determines its quality and degree of brightness.

The cut of a diamond is determined by three factors:

Cut precision
How the measurements and angles relate to the different parts of the stone

Symmetry
The accuracy with which a diamond's numerous facets join and meet

Polish
The complexities and placing of the facet shapes, as well as the external finish of the diamond

2. CARAT

The carat weight of a diamond determines its price and is unquestionably the most visible attribute of a diamond. It is also the most goal-oriented of the four C’s. It should be noted that carat and size are not synonymous; carat refers to a diamond's exact weight, whilst size refers to its dimensions. In general, the greater the price per carat, the larger the diamond.

The carat weight of a diamond can vary depending on its shape, such as round brilliant, princess, pear, oval, cushion, marquise, emerald, radiant, or heart. A bigger diamond may appear larger, and two diamonds of the same carat weight may differ in size if one is cut deeper than the other.

3. CLARITY

Inclusions are internal flaws found in diamonds. We reject any diamond with noticeable imperfections to the unaided eye.

4. COLOR

Color refers to the hue of a diamond and is based on the GIA diamond colour scale. The absence of colour influences the grade and value of a diamond.
The gemological standards in this section only apply to individually registered engagement diamonds set in specific ring designs.
