When selecting a diamond, the most important factors to consider are shape, cut, colour, clarity, carat weight and fluorescence. Cost is always a consideration, and we know that there is a diamond for every budget. We have years of experience helping people find jewellery that’s right for them in every way.


Although a diamond’s colour and clarity are dictated by nature, the cut of a diamond with its angles and proportions is determined by the human hand. When purchasing a diamond, the cut is the most important factor to consider as this is what determines the vibrancy and brilliance of a polished diamond. A well cut diamond allows light to reflect and refract back to the viewer, giving the diamond maximum brightness.


While diamonds come in a variety of colours, the “colour” in a white diamond actually refers to the degree to which a diamond appears to be absent of colour or colourless. While brilliance (sparkle) is the first thing you notice about a diamond, colour is the second.

Diamonds are graded on a colour scale which ranges from D (colourless) to Z (strong yellow or brown colour). The higher the colour grade on the colour scale, the less colour there is in the diamond, and therefore the more expensive it will be. The whitest and most highly valued diamonds are graded D, E or F.

The importance of a diamond’s colour increases as the carat size of the diamond is bigger. This is because colour is easier to perceive in a larger diamond.


Diamond clarity refers  to the small internal imperfections or marks within a diamond (called inclusions) and surface flaws (referred to as blemishes). Due to them being made underground, almost all diamonds have small inclusions and blemishes.

These tiny, natural blemishes and inclusions are most often not able to be seen with the naked eye and therefore do not affect the beauty of the diamond in any way. In fact, they are often referred to as ‘internal characteristics’ by diamond experts as they are what give diamonds their personality and uniqueness.

The importance of clarity increases with the size of your diamond as they become more visible. A diamond’s shape will also be an important factor when considering clarity, as some shapes conceal the inclusions better than others.

Carat Weight

Although commonly thought to refer to the size of a diamond, a Carat is actually a standard unit of measure defining the weight of a diamond. This weight  is expressed in ‘points’ on a scale up to 99, with 100 points equaling one carat. Diamonds of the same carat weight do not always have the same dimensions because they are cut differently. For example, a 3 carat diamond with a poor cut grade may look smaller than a 2 carat diamond with a better cut if it has been cut with a deep pavilion. Correctly cut diamonds have what is referred to as ‘ideal’ dimensions.


Fluorescence takes the form of a phosphorescent after-glow that occurs when the diamond is exposed to ultraviolet light (including sunlight). It is a common misconception that fluorescence is a negative quality. This is not always the case. In many instances, it improves the colour and brightness of a diamond (for example those with low colour grading). Fluorescence can, however, impact the value of a diamond when the fluorescence is strong as it may make the diamond appear oily or cloudy.


When purchasing a diamond, the choice of shape is a very personal and subjective decision. The relative importance of the elements of cut, clarity and colour all vary depending on the shape of the diamond you choose. At REIGNE we apply the same stringent standards on all of our diamond shapes, meticulously choosing the most beautiful and brilliant diamonds irregardless of shape.

Listed below are the most popular shapes sold at REIGNE Jewellery.


Round Cut

The most popular shape is still the classic round brilliant for its bright and uniform optical properties. A round brilliant shape is the original ‘modern’ cut, developed in the early 20th century. Consisting of 58 facets, this versatile designed diamond is designed to produce as much sparkle as possible.

Princess Cut

Princess cut diamonds are exceptionally brilliant due to its many angles. They are available in both square and rectangular shapes and are a popular choice for classic engagement rings.

Cushion Cut

Cushion cut diamonds (also known as ‘pillow-cut’ diamonds) have rounded corners and larger facets to increase their brilliance. These diamonds are also available in square and rectangular shapes. For those looking for a “vintage” look, a cushion cut would be the perfect diamond.

Emerald Cut

Emerald cut diamonds have a unique optical appearance because of the rectangular step-cut facets. This cut showcases the diamond’s original clarity and colour beautifully.

Pear Cut

Inspired by oval and marquise cuts, the pear cut features both a rounded and pointed end. The pear cut creates a soft look with the illusion of length for shorter fingers.

Oval Cut

An oval diamond’s elongated shape can be cut with the same number of facets as a round brilliant diamond, thereby potentially having as much brilliance as the classic shape. Like the pear cut diamond, oval cuts help create the illusion of length for shorter fingers.

Radiant Cut

Radiant cut diamonds feature uniquely cut corners, combining the lines of an emerald cut with the brilliance of a round diamond.
