Choosing Your Perfect Diamond
Diamonds come in all shapes and sizes, and there is sure to be one to suit your taste, style and budget. When choosing a diamond, there are several essential aspects to be considered, commonly known as the four Cs: colour, clarity, cut and carat.
Diamonds are graded by colour – in most cases, the more colourless the diamond, the higher its value. The exceptions to this rule are the fancy coloured diamonds, such as pinks, yellows and blues.
GIA is the industry standard for measuring diamond colour. The letter D represents the most colourless diamonds, ranging up to the letter Z for a light yellow or brown diamond.
As you can imagine, colour grades are judged under controlled lighting and precise viewing conditions.
Clarity is a measure of the flawlessness of a diamond, and the clarity rating affects the beauty and price of each stone.
Virtually all diamonds have some imperfections known as inclusions and blemishes.
The industry standard rates all gem-grade diamonds on a scale from FL for flawless, to I3 for heavily included.
A diamond is described as ‘flawless’ if no external imperfections or internal flaws are visible under 10-power magnification. Flawless diamonds are scarce – and impacts the price accordingly.
The most critical of the four Cs is the cut of your diamond, as it not only governs its shape, but also the fire, life and brilliance it displays.
Diamonds are carefully cut and polished to emphasise the stone’s brilliance. Traditional diamond shapes include Brilliant, Princess, Oval, Marquise, Pear, and Emerald.
A diamond should work as a mirror, capturing the light and reflecting it from one facet to another before sending it back to the crown of the stone.

The weight of a diamond is measured in carats. One carat is equivalent to 0.200 grams – but weight alone doesn’t determine the diamond’s value.
When you compare two diamonds of the same weight, the value depends on the quality of each stone.
When you compare two diamonds of equal quality, the larger stone will usually hold considerably more value. Typically, a two-carat diamond will be worth more than twice as much as a one-carat stone.
