Carat Weight

The unit of measurement for weight of diamonds is carats, with a one carat diamond weighing 0.2 grams. Obviously, as the carat weight of the diamond goes up, then so does the price.

Two stones that appear to be the same size, however, may have differing carat weights. This is a consequence of the cut and spread of the stone.

Colour

At a glance, most diamonds appear to the naked eye to be colourless, however on closer inspection diamonds can appear to be yellow. The appearance of yellow within the stone is an indication of the presence of impurities in the diamond’s carbon composition, with nitrogen producing the yellow colour.

For non-coloured diamonds, the more colourless the stone, the more expensive it will be.

Clarity

In every diamond there are tiny imperfections called “inclusions”, and they vaguely resemble scratches or little marks. Inclusions are natural imperfections within the stone.

The range of clarity varies from the no inclusions (Flawless) to stones that have inclusions visible with the naked eye (Included).

The fewer the inclusions, the more expensive the diamond will be.

Cut

The cut of a diamond is ultimately the factor in how a diamond interacts with natural light and therefore affects how sparkly it is, in fact Tiffany & Co. believes that the cut of the ring is the most important of the four C’s.
The cut of a diamond affects how sparkly the stone is when hit with light, meaning that two stones with the same colour and clarity ratings can appear very different if one has a greater quality of cut than the other.

The better the cut of the diamond, the more expensive the stone will be.

It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

Polish

Polish refers to how smooth the facet of the diamond is, with the cut and polish processes sometimes affecting the surface’s smoothness. The polish of a diamond is given a grading on a scale from ‘Poor’ to ‘Excellent’.

Symmetry

The symmetry of a diamond affects the sparkle of the stone as it incorporates the way that the facets have been cut and how they intersect and align. The better the symmetry of a diamond, the more it will sparkle and therefore be more desirable.

Fluorescence

The fluorescence of a diamond is the amount at which it emits a soft glow when exposed to ultraviolet (UV) light. The glow is typically blue and is found in approximately 30% of all diamonds.

Shape

Like snowflakes and fingerprints, no two diamonds in the world are identical. They come in a wide variety of different shapes, with each shape having different characteristics affecting the brightness, sparkle and appearance of the stone. The most popular diamond shape is the round brilliant cut, which is regarded as the shape with the most sparkle as a result of the way it has been cut, which allows for the optimum refraction of light.

Measurements

The measurements of a diamond are usually given in millimetres and refer to the length, width and height of the stone. Measurements and specifically the proportions of the stones are an important indicator for the diamond as it affects the way that light travels through the stone which ultimately results in how sparkly a diamond is.
