This is the most important factor you must consider when buying real diamond jewellery. That’s because, it is the cut that determines the brilliance of your diamond. Simply put, the better the cut, the more it will sparkle. Gemologists suggest that you should always go for the best cut grade within your budget.
When your diamond is well-cut, light will enter it from the table and travel to its pavilion. It will seem as if your diamond is shining from within and reflecting light back to your eyes. But in a poorly-cut diamond, light seems to be leaking out from the bottom and sides. If it has been cut poorly, your diamond may seem to be dull, even if it has perfect colour grade and clarity.
This is the second most important factor that determines the quality and diamond jewellery price. It’s important to know that colourless diamonds are the best ones because they allow the maximum refraction of light or sparkle. So look at the lack of colour when you are buying diamond jewellery online or otherwise. The more colourless a diamond is, the better will be its quality.
The colour is graded on a scale of D to Z. Diamonds between D and F is colourless, and those between G and J are near-colourless.
Rarely will you find a perfect diamond because almost all of them have inner flaws that occur during their formation process. The number of these flaws, their size, and how visible they are determine the clarity of a diamond.
These imperfections are sometimes called inclusions. Diamonds with the highest clarity grades have the smallest and least inclusions. Go for an eye-clean diamond, which means the inclusions cannot be seen with the naked eye.
Carat weight is the most misunderstood aspect of a diamond. Many believe it refers to the size, but actually this is a measure of the diamond’s weight. One carat is one-fifth of a gram or 0.20 g.
So don’t always go for size. Bigger is not always better. A well-cut diamond with good clarity and colour, but one that is smaller in size could very well be better than a larger stone that has mediocre clarity, cut, and colour.
There’s no dearth of good diamond jewellery in India. But make sure to check out the 4Cs before you buy diamond jewellery – cut, colour, clarity, and carat.
Diamond Grading Certificate- the 5th C
