Diamond Inclusions: Cloud

clouds in diamonds

Diamond Inclusions are blemishes that are present inside the structure of the diamond and are known as inclusions. When carbon is transformed into a diamond, it is subjected to extremely high temperatures and pressures, leading to inclusions forming. When evaluating the diamond’s clarity, inclusions are an essential factor to consider.

Cloud

Inside a diamond is a cluster of incredibly minute and nearly indistinguishable points. At a magnification of 10 times, it isn’t easy to see clouds in diamonds with superior clarity. The grading report for a diamond with low clarity may say that the clarity is based on clouds that cannot be seen. This is because clouds obscure the view of internal characteristics.

A cloud is basically a cluster of seriously tiny inclusions known as ‘pinpoints’ (read more about pinpoints here). On their own, these pinpoints would be impossible to spot, but when they get together and party up close to one another, they can cause a ‘cloud’ to form. It’s known as a cloud.

It can often make the diamond appear hazy or fuzzy, like those days when the sun can’t quite blast through the dust and smoke in the air:

Inclusion will be called a cloud when there are three or more pinpoints huddled together in the same place (this is according to the GIA who are pretty much the authority on these things). Because these clouds cannot affect the overall durability of the stone (i.e. they will not multiply/expand over time, and will not cause the stone to crack or break), they should not be deal breakers. If the clarity grade on a diamond is a VS1 or above, any clouds will most likely not affect the optics of the diamond at all.

That being said, the more severe-looking clouds can be a real bummer. Not only can they look like a gray blob inside the diamond, but they can also stop the light from bouncing around inside there, causing the diamond to look dull and lifeless. If a diamond has been given a lower clarity grade, for example, the cloud could be the culprit. That will especially be the case if the cloud(s) are located at or near the table (top) of the diamond. This diamond is basically one big cloud, and it’s turned milky.

Make sure that any clouds are transparent, and that the clouds themselves are not too dense. You also need to make sure that the cloud doesn’t take up more than one-quarter of the diamond itself (no matter where the cloud is located in the stone). The less space taken up by clouds, the more light can bounce around in there giving you a sparkly diamond.

Can you locate clouds in diamonds?

Several factors can make your diamond seem hazy, dull, or clouded. Without seeing the gems in question, experts have difficulty providing advice. It is not the surface of the diamond that causes cloudiness but rather the interior structure of the diamond. This is why we rarely succeed in reversing the effect of a hazy appearance. If the diamonds you are looking at have a solid blue fluorescence, the diamonds will most likely appear cloudy, greasy, or obscured. Additionally, the diamonds will seem less straightforward than usual.

What does a cloud look like in diamonds?

A diamond may have a feature called a cloud, which is a cluster of tiny, indistinguishable pinpoints. Under 10x magnification, cloud inclusions in diamonds with a higher clarity grade are frequently challenging to observe. Several instances in which the grading report for diamonds with poor clarity may say that the clarity is based on clouds that are not apparent to the naked eye.

Does lab diamond get cloudy?

Some of our competitors will mention to our customers from time to time that the appearance of a lab-grown diamond may change throughout its lifetime. This is not the case with diamonds created in a laboratory. We pack all of our laboratory-grown diamonds with a lifetime warranty at www.rarecarat.com.

Lab-grown diamond

When a lab-grown diamond is created, cutting-edge technology is used to replicate the process that occurs naturally. The outcome is a synthetic diamond identical to a natural diamond in terms of its chemical, physical, and visual properties. A lab-grown diamond is not a fake. They are devoid of cubic zirconia. All mined diamonds look and are manufactured similarly at www.rarecarat.com.

If you haven’t read through that general intro post on all this jazz, we suggest you pop your fingers on that mouse and click here so you can read it. It will give you a little grounding on the whole topic before you launch fingers first into this intriguing post on ‘clouds’.

Lab diamonds are grown under the chemical vapor deposition method.

Chemical vapor deposition is more recent than the other approach. This method recreates the conditions in interstellar gas clouds that led to the formation of diamonds. The process utilizes lower pressures and more compact pieces of apparatus. A diamond seed is put into a vacuum chamber before the CVD begins. This space is for a temperature of around 1,800 degrees Fahrenheit, after which it is filled with carbon-rich gases. Because of these extraordinarily high temperatures, the gas is converted into plasma, which then causes the release of carbon particles. These carbon bits are placed above the diamond seed, ultimately developing the diamond.

Type IIA diamonds, found in nature only currently, can be produced by this process. Scientists can use this information to determine whether or not a diamond was formed naturally or in a laboratory. Compared to nitrogen-exposed, High-pressure, high-temperature diamonds, type IIA diamonds have the highest level of chemical purity because they do not include any nitrogen or boron impurities.

Can you tell lab diamond?

Is it possible for a jeweler to determine whether or not a diamond was made in a laboratory? No. The natural and lab-grown diamonds produced by Ada are of the same quality. Therefore, it is impossible to tell the difference between the two. Jewelers cannot discern the difference between a diamond created in a laboratory and one discovered on the ground using instruments such as microscopes and loupes.

Difference Between Clarity Grades?

For appearance sake, clarity grades: FL, IF, VVS1, VVS2, VS1, VS2*, and SI1* can all be called eye-clean. This means you cannot see any inclusion with the unaided eye or no magnification. Clarity-wise, diamonds from FL all the way to SI can appear the same. But for SI and VS stones some precautions should be made.

For smaller stones under 1.00ct, this eye-clean range extends into the SI ranges, but it is usually safer to stay on the VS2 side to be safe. For larger stones above 1.00 ct, especially into the 2+ range, a few diamonds of VS2 quality might not be eye-clean. Thus for these stones, VS1 is the safe bet to have an eye-clean stone. So if a flawless look is what you are looking for, a stone from flawless to VS and sometimes SI should satisfy your need for the best bling.

Conclusion

A diamond comprises tiny, almost invisible points. At a magnification of ten times, it is hard to see clouds in diamonds with great clarity. A diamond’s grading report may say its low clarity is because of clouds that can’t be seen. When making a lab-grown diamond, cutting-edge technology is used to copy what happens in nature. The result is a synthetic diamond that looks, feels, and acts like a natural diamond. A diamond made in a lab is not a fake since it is sold at www.rarecarat.com. Rarecarat is a brand that is reputable and all its products are of superior quality. You can reach their website and get the best of the best.
