Few fine jewellery purchasers fully understand the magnitude of the four attributes of diamonds, or the 4Cs: Carat weight, colour, clarity and cut.

Carat: The carat weight measures the mass of a diamond. One carat is defined as exactly 200 milligrams (about 0.007 ounce). The value of a diamond increases exponentially in relation to carat weight, since larger diamonds are both rare and more desirable for gemstones.

 

Colour: Diamonds are graded for colour on a scale of “D” or colourless, to “Z” or dark yellow. A chemically pure and structurally perfect diamond is completely transparent with no hue or colour. Almost no gem-sized natural diamonds are absolutely perfect. The colour of the diamond may be affected by chemical impurities and structural defects in the crystal lattice. The hue and intensity of a diamond’s colouration can enhance or detract from its value.

 

Clarity: Flaws inside a diamond are commonly referred to as inclusions. These imperfections may be crystals of a foreign material, another diamond crystal or structural imperfections (tiny cracks that can appear whitish or cloudy). The number, size, colour, relative location, orientation and visibility of the inclusions can all influence the clarity of a diamond.

 

Cut: The cut of a diamond describes the manner in which a diamond has been shaped and polished from its beginning form as a rough stone to its final gem proportions. The cut describes both the shape a diamond is formed into as well as the quality of workmanship. Round or brilliant is a favourite among engagement rings. Emerald cut is rectangular in shape with facets polished diagonally across the corners. Marquise or pointed boat shape is long and narrow and tends to slim the finger. Pear shape is popular in rings as well as pendants. An adaptation of the brilliant shape, oval tends to appear larger than a brilliant of the same carat weight.
