Guide To Buying Diamonds

Buying a diamond for the first time can feel like an overwhelming and daunting task. We guide and educate you on your choice and make your experience one that is enjoyable and memorable.

Only Mother Nature can create something as exquisite as a diamond. A diamond is composed of pure carbon, which makes it the hardest substance known. Formed in intense heat and pressure deep under the earth, carbon deposits form over many millions and even billions of years, this makes a diamond one of the rarest gems on the planet.

The Four C'S

You’ve probably heard about the 4Cs of a diamond, and you may even know that it stands for diamond cut, color, clarity and carat weight. Below we take a closer look into the individual 4Cs:

Cut

One of the most important characteristics to consider when buying diamonds is the ‘cut’. ‘Diamond cut’ refers to the angles and proportions created when transforming a rough diamond into a polished diamond. There are two meanings in relation to the ‘cut’ of a diamond. The first is the actual physical shape of the diamond.

Diamond Colour

Colour

All diamonds will fall within a range from ‘D’ (colourless) to ‘Z’ (light yellow). The higher or closer a diamond is to having no colour (D), the more valuable it becomes. This is due to the fact that the light refractions reflect off the white diamond for a truly dazzling and sparkling diamond. Diamonds can also be found in many different colours, known as ‘fancy’ colours. These colours include yellow, brown, pink and blue, which makes these diamonds particularly rare and valuable.

Clarity

The clarity of a Diamond is most commonly known as ‘nature’s fingerprint’ or ‘birthmark’. The majority of diamonds contain ‘inclusions’. The size or quantity of these in the diamond depends on the clarity grading that the diamond is given. These inclusions are natural characteristics of a diamond (such as fractures or minerals). Most, however, are invisible to the naked eye. The fewer inclusions in a diamond, the greater the clarity and the higher the value.

Carat​

The carat of a diamond is actually a measure of its weight, not its size.
