Diamond Clarity

The very thought of diamonds conjures up pictures of everything grand. These sparkling and alluring gemstones are often called the epitome of perfection. And they have become the go-to gemstone whenever people want to look drop-dead gorgeous. There is no doubt why. It is the hardest gemstone available on the earth and the highly organised form of carbon. You cannot begin to describe its beauty and shine, can you? But that’s not enough when you buy diamond jewellery online or offline. You, on the other hand, should know the fundamentals of this gemstone.

Seasoned diamond buyers, collectors, and investors know what makes these precious gemstones as valuable as they are. They give primary importance to the four Cs of diamonds. Cut, colour, carat, and clarity are those four Cs that determine the worth of a diamond. While the cut, colour, and carat aren’t hard to find, it takes a fine eye to see how clarity affects a diamond’s beauty and price. Here is everything you should know about the clarity of diamonds.

What is the Clarity of a Diamond?

As you know, diamonds are made of carbon. In fact, they are the most concentrated form of carbon available to us. Natural diamonds take millions of years to form. They face extreme heat and pressure in the earth’s mantle. Most of such naturally occurring diamonds have flaws or imperfections. These flaws include different amounts of scars and inclusions on the surface of a diamond, which are called blemishes. Inclusions are internal features trapped in it during its formation. Very rarely do diamonds appear in a perfect and ideal condition. And therefore, they are very expensive as well. The scars or inclusions on diamonds are nature’s birthmarks. They are the features that make these gemstones unique.

So, what do these blemishes and inclusions have to do with the clarity of a diamond? To put it simply, a diamond’s clarity refers to how clean it is. It is the metric used to grade the visual appearance of a diamond.

Flaws, Clarity, and Price

When you buy diamond rings, necklaces, bangles, earrings, etc., remember that their clarity is inversely proportional to flaws. That is, the lesser the flaws, the higher the clarity grade of a diamond will be. The clarity of a diamond can have a great impact on its value as well. A diamond with high clarity is a lot costlier than a low clarity one even if they have the same cut, carat value, and colour. However, most inclusions and flaws are not detectable by the naked eye.

A diamond’s clarity is influenced by many factors. The quantity, colour, and size of the inclusion are some such key factors. It may also change based on how visible the inclusion is. Similarly, its orientation and location also determine the clarity of diamonds.

Understanding the Diamond Clarity Chart

Every diamond is unique. So are their flaws. Since the flaws are mostly microscopic, gemmologists use magnification up to 10x to inspect diamonds. And they do that keeping the diamond in the face-up direction. If any blemish or inclusion is not visible on viewing the diamond from the top, it won’t help in finding the clarity grade. Therefore, experts use loupes or microscopes to analyse the type, position, and size of all the inclusions.

Skilled graders find different clarity features using the 10x magnification. They map the locations of the inclusions the same way on diamond plots. These plots refer to small maps for individual diamonds. They help in classifying each diamond. Every diamond has a different internal pattern. This means that no two diamonds are ever the same. And the diamond plots are like fingerprints that help to identify each individual diamond.

Gemmologists grade the results of the analysis on a diamond clarity chart. The different grades on this chart and their features are as follows:

FL and IF – Flawless, Internally Flawless

As the name suggests, diamonds with these grades are flawless. The 10x magnification doesn’t show any internal inclusions when you view a diamond with this clarity. However, such diamonds may or may not have surface flaws or blemishes.

VVS1 and VVS2 – Very Very Slightly Included

This grading means there are only some inclusions that are hard to see even with 10x magnification. Inclusions in the VVS1 gems are visible from the bottom-up view while that of VVS2 are visible in the face-up view.

VS1 and VS2 – Very Slightly Included

When small inclusions, such as crystals of other elements, show up in diamonds under the 10x magnification, they get this clarity grading. You need to look very hard to find these imperfections. Of VS1 and VS2, the former has a high clarity grade than the latter.

SI1, SI2, and SI3 – Slightly Included

Diamond with a presence of clear inclusions under magnification feature this low on the clarity chart.

I1, I2, and I3 – Included

These diamonds contain obvious inclusions. You can see the inclusions in these diamonds with 10x magnification and often with the naked eye. Such diamonds tend to have low transparency and usually lack brilliance.

What Clarity Rating Should You Choose?

To select a gem with the right clarity rating, you should keep a few things in mind. Firstly, are you looking for a diamond with no inclusions? Or can you tolerate negligible amounts of them? If yes, choose one with the FL-IF grade or any VVS grade. They will be more expensive than the other grades of diamonds, but they are of high quality. And they look near perfect too.

Diamonds under the VS grade don’t cost as much as those with premium clarity rating, but they are also high-quality stones. However, if you are looking to cut the cost, you can go for an SI-rated diamond. Here, you need to ensure that the inclusions aren’t obvious. If you are looking for a diamond with more carat weight at a lower price, choose one in the SI3 or I1 range.

When you buy any diamond other than the flawless kind, check the location of the flaw and inclusions. The inclusions closer to the side facets affect its beauty less than if they are at the centre.

Buying Tip to Avoid Making a Common Clarity Mistake

When investing in a diamond, it’s easy to make mistakes. Do you know what the most common mistake people make is? They choose a diamond with very high clarity grade thinking that it’s a good investment. You should choose the clarity that suits your needs the best. Avoid buying a flawless diamond just because it looks perfect. Most of the relatively lower priced stones often have only tiny flaws that are hardly visible. The microscopic flaws don’t affect a diamond’s physical beauty or its value. Weigh your needs and make a wise choice.

So, next time when you buy a diamond ring or pendant, don’t just blindly go for a pretty one. Ask your jeweller about the clarity of stones used in it. Check the clarity chart. And then make your pick.
