If you’re planning to buy a diamond fo engagement rings, pendant, bracelet or earrings but don’t know where to start? This quick diamond guide will help. Usually most people looking to buy a diamond are clueless and intimidated by the complexity of diamond grades and why they are so expensive. All it takes is a little research and to learn the basic factors of a diamond. Basically all you need to know is the 4-Cs of a diamond – the four important factors that contribute to its price and quality.
Let’s start with diamond cut – it’s the cut of a diamond that determines the symmetry, proportions and ability to reflect light which all contribute to its fire and sparkle. Although there is no visible difference between cut grades, there is a difference in the perfection of proportions that determine how much light reflects through. Usually you have the option to choose between three cut grades –
- Good Cut –
- Very Good Cut –
- Excellent Cut – also referred to as an ideal cut diamonds where the diamond is perfectly proportioned and is usually 5-10% more expensive.
Diamond Carter Weight
The weight of a diamond is measured in carats – 1 carat is equal to 0.2 grams. Diamond with a higher carat weight are more valuable than diamonds with a lower carat weight. A carat can also be divided into points, where one point is equal to 0.01 and 0.50 points is the equivalent of half a carat. Carat weight does not always determine the size of a diamond as other factors influence size like the cut and the shape of the stone.
The appearance of a diamond cab be influenced by its colour grade or lack of colour when referring to white diamonds. Colour grades range from D – colourless to Z light yellow. The higher the colour grade the more ability to reflect light and exhibit fire, so diamonds with a lower colour grade with noticeable yellow colour will not have the same fire. Usually grades between D to G have no noticeable difference in colour to the visible eye.
Clarity refers to the amount of inclusions or marks a diamond has. These inclusions are usually not clear to the naked eye and the fewer inclusions the more expensive a diamond will be.
