Do Lab-Grown Diamonds Have Inclusions? Everything You Need to Know

Lab-grown diamonds have been making waves in the jewellery world for some time now. As an ethical and affordable alternative to natural diamonds, they offer the same beauty and durability without the environmental and ethical concerns of traditional mining. But just like natural diamonds, lab-grown diamonds aren’t always flawless. One question that often arises is: do lab-grown diamonds have inclusions? Let’s dive into this topic and explore everything you need to know about inclusions in lab-grown diamonds.

In short: Yes. Lab-grown diamonds form inclusions during growth — typically tiny metallic inclusions (HPHT) or pinpoints and clouds (CVD) — graded identically to mined diamonds on the GIA/IGI IF-to-I3 scale. VS1-SI1 lab-grown stones are eye-clean and indistinguishable from flawless to the naked eye.

What Are Inclusions in Diamonds?

Inclusions are internal characteristics or imperfections found within a diamond. These can occur during the diamond's natural formation deep within the earth or during the growth process in a laboratory. Inclusions come in various forms, such as tiny crystals, fractures, or other material trapped inside the diamond.

In both natural and lab-grown diamonds, inclusions are common. They affect the clarity of the diamond and are used as one of the key factors in determining a diamond’s value. The fewer the inclusions, the higher the clarity grade—and typically, the higher the price. To learn more about how inclusions impact clarity, check out our lab-grown diamond collection.

Do Lab-Grown Diamonds Have Inclusions?

Yes, lab-grown diamonds can have inclusions. While lab-grown diamonds are created under controlled conditions in a laboratory, the growth process can still result in imperfections, just as in natural diamonds. These imperfections are a natural part of the diamond-growing process, whether it takes place over millions of years in the earth or within a few weeks in a lab.

That said, the types of inclusions found in lab-grown diamonds can differ slightly from those found in natural diamonds due to the differences in how they form. Inclusions in lab-grown diamonds are often the result of tiny particles or irregularities that form during the growth process, whether through HPHT (High Pressure High Temperature) or CVD (Chemical Vapour Deposition) methods.

Types of Inclusions Found in Lab-Grown Diamonds

The inclusions found in lab-grown diamonds can vary depending on the growth method used:

• HPHT Diamonds: Diamonds created using the HPHT method are more likely to contain metallic inclusions due to the metal used in the growth process. These inclusions can sometimes appear as small metallic particles or as growth-related patterns within the diamond.
• CVD Diamonds: Diamonds grown using the CVD method typically have fewer metallic inclusions but may exhibit other types of imperfections, such as cloud-like inclusions, strain patterns, or graphitic inclusions. These often result from the gaseous environment in which the diamond grows.

While inclusions are present in both lab-grown and natural diamonds, many of the inclusions found in lab-grown diamonds are unique to the growth process and can often be identified under a microscope.

Do Inclusions Affect the Value of Lab-Grown Diamonds?

Inclusions do play a role in the value of lab-grown diamonds, just as they do with natural diamonds. The clarity of a diamond, which is affected by the number, size, and position of inclusions, is a key factor in determining its value. Diamonds with fewer or less noticeable inclusions are considered higher in clarity and tend to command higher prices.

However, inclusions aren’t necessarily a bad thing. Many inclusions are so small that they are invisible to the naked eye and have little to no impact on the beauty of the diamond. In fact, inclusions can make a diamond unique, as no two diamonds will have exactly the same internal characteristics.

For buyers on a budget, choosing a diamond with minor inclusions can be a smart way to get a larger or higher quality stone for a lower price. These inclusions are often microscopic and won’t affect the diamond’s overall appearance when viewed in everyday settings.

How Are Lab-Grown Diamonds Graded for Inclusions?

Lab-grown diamonds are graded for inclusions in the same way as natural diamonds. The Gemological Institute of America (GIA) and other gem grading laboratories use a clarity scale that ranges from Flawless (FL) to Included (I).

A Flawless diamond has no visible inclusions under 10x magnification, while an Included diamond has noticeable inclusions that can affect its brilliance and durability. In between these two extremes, there are grades such as Very Slightly Included (VS) and Slightly Included (SI), which indicate diamonds with minor inclusions that are often not visible without magnification.

It’s important to check the clarity grade of any lab-grown diamond before purchasing to ensure it meets your expectations in terms of quality and appearance. If you're considering a specific diamond cut, our emerald lab-grown diamonds provide an elegant and clear look.

Can Inclusions Be Seen in Lab-Grown Diamonds?

The visibility of inclusions depends on the diamond’s clarity grade. Diamonds with higher clarity grades, such as Flawless or Internally Flawless (IF), will have no visible inclusions even under magnification. On the other hand, diamonds with lower clarity grades, such as SI or I, may have inclusions that are visible to the naked eye.

Inclusions are often less noticeable in certain diamond cuts, such as brilliant round cuts, which reflect light in such a way that small imperfections are masked. Similarly, certain settings, such as bezel settings, can help minimise the visibility of inclusions by covering parts of the diamond where they are present.

Frequently Asked Questions (FAQs)

Can lab-grown diamonds be flawless?

Yes, it is possible for lab-grown diamonds to be flawless, meaning they have no visible inclusions or blemishes under 10x magnification. However, Flawless lab-grown diamonds are rare, just like Flawless natural diamonds.

Are inclusions in lab-grown diamonds different from natural diamonds?

Inclusions in lab-grown diamonds can differ from those in natural diamonds due to the different growth processes. For example, lab-grown diamonds may have metallic inclusions from the HPHT process, which are not found in natural diamonds.

Do inclusions weaken a lab-grown diamond?

Minor inclusions do not typically weaken a lab-grown diamond. However, large or poorly placed inclusions could affect the durability of the diamond, particularly if they are near the edges where the diamond is most vulnerable.

How can I tell if a lab-grown diamond has inclusions?

The best way to identify inclusions in a lab-grown diamond is by viewing it under 10x magnification. Most jewellers offer this service, or you can refer to the diamond’s clarity grade on its certification report.

Should I avoid lab-grown diamonds with inclusions?

Not necessarily. Inclusions are common in both lab-grown and natural diamonds. Many inclusions are not visible to the naked eye and do not affect the beauty or durability of the diamond. If you are on a budget, diamonds with minor inclusions can offer great value.

The Impact of Inclusions in Lab-Grown Diamonds

Inclusions are a natural part of any diamond, whether it is grown in a lab or formed naturally over millions of years. While inclusions do affect a diamond’s clarity and value, they don’t necessarily detract from its beauty. In fact, for many buyers, inclusions offer a way to purchase a high-quality diamond at a more affordable price.

When shopping for a lab-grown diamond, it’s essential to consider clarity alongside other factors like cut, carat, and colour. Whether you’re seeking a Flawless diamond or one with minor inclusions, lab-grown diamonds offer stunning, ethical, and affordable options for every occasion.
