The quality of diamonds has been translated into 4 Cs.
These 4 properties of diamonds give an idea of the quality and identify the stone used in a diamond ring.
Let’s take a 1 carat diamond engagement ring with a 1 carat diamond as an example. Carat expresses the weight of the diamond. A 1 carat diamond weighs 0.2 grams and is divided into 100 points. The scale gives a very precise diamond weight and is rounded off to two decimal places.
The colour of most diamonds used in diamond engagement rings and other diamond jewellery varies from white to yellow. The correct colour of a diamond is determined on the basis of an international colour or master scale. The colour ranges from D, colourless (the whitest and the most desired), to Z, the most yellow.
Apart from colourless or white, a diamond may have other colours like orange, brown, blue or pink, etc. The most intense colours of these shades are called ‘fancy colours’. These ‘fancy’ coloured diamonds are extremely rare and therefore very expensive.
For diamond engagement rings, G & H colours are the best value for money. Lower grade colours have a visible yellowish tinge and the prices of high-grade colours tend to rise above the ideal price-quality ratio due to their rarity. However, high-grade colours (D, E and F) are the best option for investment purposes.
