When shopping for a diamond ring, itâ€s helpful to have some knowledge on the 4Cs to choose the diamond for you. As the globally accepted standards that determine the quality of a diamond, the 4Cs stand for cut, clarity, carat and colour.\

Arguably, cut is the most significant factor because it affects how much light reflects off the diamond surface – determining its sparkle. Diamond clarity refers to how pure and rare the stone is, while carat refers to the weight of the diamond (1 carat is 0.2 grams). The last factor is the visible colour of the diamond, the absence of colour signifies a rarer stone.
