A diamonds value, rarity and beauty are determined by factors that are commonly known as the 4 Cs, these are: colour, clarity, carat and cut. Before deciding on your diamond jewellery, it is important to understand why two diamonds that may look exactly the same are actually valued differently. Before buying a diamond ring or jewellery, the following section will help you to understand the 4 C’s in more detail and will be useful when studying the diamond’s brilliance, beauty and quality.
Diamonds and other gemstones are weighed in metric carats. One carat is 0.2 grams and a carat is split further into 100 points (a diamond weighing 50 points is a half carat diamond).
In white or colourless diamonds, colour is universally graded using an alphabetical scale from D to Z with D being the highest grade.
Diamonds are formed under extreme heat and pressure deep inside the earth and often display internal inclusions or external blemishes.
The quality of the cut of a diamond is important, because it dictates a diamond’s fire, sparkle and brilliance.
