Here at Caliber Jewellery, all our diamonds are hand selected to ensure they are cut proportionally, allowing light to symmetrically pass through the stone, creating the perfect sparkle. 

What you need to know

The Four C's

When purchasing a diamond, whether it is a loose diamond, or part of a piece of jewellery like an engagement ring. You should always know what specification this diamond comes with, below we talk a bit about what to look out for when buying a diamond. 

Cut

The beauty of a diamond is determined by how well it is cut. The cut is split into three sections of grading which are: symmetry, proportion and polish. Each section is further examined according to parameters called: Excellent, very good, good and fair.

Clarity

Diamonds naturally occur under extreme conditions over long periods of time. As these conditions vary, diamonds will display imperfections which are known as inclusions. The term Clarity is used to define the purity of diamonds and can be categorised in terms of size, location and quantity of imperfections in diamonds.

Carat

Carat is an expression to determine the weight of diamonds. The size is indicated by the following: 1 CT = 100 points = 0.2 grams

Colour

Most diamonds range in colour and are determined by comparison with a series of master Stones. Diamond colours range from colourless to slightly yellow, colourless being the highest grade. Furthermore, fluorescence can be used as another identification for diamonds. ('nil', 'slight', or 'medium' to 'strong")

What you need to know

Certification & Quality

After the 4 C’s the most important factors to consider with your diamond are Symmetry, Fluorescence, Polish and certification. Below we discuss each of these in more detail. 

Symmetry​
Diamond Symmetry is a reference to how symmetrical, well aligned and conformed the facets of a diamond are. The GIA Symmetry is ranked the same as the polishing grades.
Certification​
Diamond certificates are extremely important when purchasing them as loose diamonds or on a piece of jewellery. It gives a summary of specifications such as carat, cut, clarity. They also ensure their authenticity and quality of the stone.
Fluorescence​
Diamonds have a tendency to emit soft glows when they are exposed to UV (ultraviolet) light, such as sun rays. This is known as fluorescence, and is important to consider when buying diamonds.
Polish
During the manufacturing process of a diamond, diamond cutters finish stones to achieve a smooth, glass like surface. The quality of this process is known as diamond polish. The GIA polish grades are: Excellent, Very Good, Good, Fair and Poor.
