Understanding Diamond Quality

When it comes to understanding diamond quality, it can be a bit overwhelming. If you’re looking to buy a diamond, you want to make sure you know exactly what all of the lingoes mean before you invest. This article should help to outline some of the regularly used terms in diamond sales so you’re completely clued-up.

There are four important aspects to buying a diamond, also known as the 4 C’s – clarity, cut, colour and carat. Carat is fairly simple; it’s the size of the diamond. Colour, again, is easy enough to understand, a completely clear diamond is the rarest and most expensive, and a diamond with yellow tones is less so. A diamond with a rating D is colorless and the scale goes all the way up to Z, which is a diamond with a yellow tint. The colour of a diamond is completely down to preference, and so you may find a diamond with a lower price because of its colour that is perfect in your eyes.

The clarity of a diamond is where it can get more complicated. There is a clarity scale of diamonds, which has flawless(FL) diamonds at the highest point, then internally flawless (IF), very very slightly included (VVS), very slightly included(VS), slightly included(SI), and included(I) as the lowest grade. Although this scale gives you an idea of which diamond is the most perfect and which are less so, it’s important to know what each of these grades means.

A flawless or internally flawless diamond is the most expensive, incredibly rare diamonds, making them very hard to find. What is worth knowing is that if you’re after a flawless diamond, you can actually choose a diamond lower on the scale and still get the same visual effects from your diamond. A VVS diamond, for example, will still appear flawless to the human eye. It’s only under a 10x microscope and with a trained eye that any of the imperfections will be able to be seen. This is why VVS diamonds are so popular; the same visual perfection of a flawless diamond with a much lower price. It’s also why VS diamonds are increasingly popular too, as although they will have more blemishes and imperfections than a VVS diamond will, they’re also incredibly difficult to see with the human eye – and quite a lot of the time, once the diamond is set into a piece of jewellery, the flaws are even harder to identify.

Knowing what the clarity classification of a diamond is incredibly helpful when you’re shopping, as it lets you know what you’re paying for. Flawless diamonds will always be hugely expensive as they’re so rare, but a VVS and VS diamond will have much lower prices respectively as they’re not as rare, VS diamonds especially. Knowing exactly what you want from a diamond is the key to getting the best offer you can; if you’re looking for a visually perfect diamond but happy with a VS diamond, you could save yourself an impressive amount.
