Lab grown diamonds are becoming increasingly popular as an eco-friendly and ethical alternative to mined diamonds. These diamonds are created in controlled laboratory environments, replicating the natural conditions that form diamonds deep within the Earth’s crust. Despite being grown in a lab, these diamonds possess the same chemical, physical, and optical properties as their natural counterparts. One important aspect that often comes up when discussing lab grown diamonds is inclusions. Inclusions in lab grown diamonds are a significant factor in determining their quality and value. In this article, we will explore what inclusions are, how they form, and their importance in lab grown diamonds.
What Are Inclusions in Lab Grown Diamonds?
Inclusions in lab grown diamonds refer to any internal imperfections or foreign materials trapped inside the diamond during its formation. These imperfections can occur during the diamond’s creation process in the lab, just as they can form in natural diamonds over millions of years. The presence of inclusions in a lab grown diamond can affect its clarity, appearance, and overall value. It’s important to note that inclusions are a natural characteristic of diamonds, whether they are lab grown or mined. They are often used by gemologists to identify and grade diamonds.
Types of Inclusions in Lab Grown Diamonds
There are various types of inclusions that can be found in lab grown diamonds. Some of the most common include crystals, clouds, feathers, and needle-like inclusions. Crystals are tiny foreign materials trapped within the diamond during its formation. These can be different types of minerals or other substances that become embedded in the diamond. Clouds refer to a group of tiny inclusions that are too small to see individually, but together, they can affect the diamond’s clarity. Feathers are small fractures or cracks that can form inside the diamond. Needles are thin, needle-like inclusions that can appear within the diamond’s structure. Each type of inclusion affects the diamond in a unique way, influencing its overall quality.
How Inclusions Form in Lab Grown Diamonds
Inclusions in lab grown diamonds form during the creation process in the laboratory. There are two main methods used to create lab grown diamonds: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). Both methods involve creating conditions similar to those found deep within the Earth’s crust, where natural diamonds are formed. During this process, inclusions can occur as a result of various factors, such as the presence of foreign materials, gas bubbles, or even slight inconsistencies in temperature or pressure. These inclusions are often microscopic in size, making them difficult to detect with the naked eye. However, they can still be seen using advanced gemological equipment.
The Impact of Inclusions on Lab Grown Diamonds
Inclusions can have both positive and negative impacts on lab grown diamonds. From a visual standpoint, inclusions can affect the diamond’s clarity, which is one of the key factors in determining its value. The clearer the diamond, the higher its quality and price. Diamonds with fewer inclusions are considered more valuable because they exhibit greater brilliance and fire. However, not all inclusions are detrimental. In some cases, inclusions can give the diamond character, creating unique patterns or adding a sense of individuality. Some people even appreciate diamonds with inclusions, as they can serve as a natural fingerprint, making the diamond truly one of a kind.
How Inclusions Affect the Value of Lab Grown Diamonds
The presence of inclusions in lab grown diamonds can directly affect their value. Inclusions lower the clarity grade of a diamond, which in turn impacts its price. The Gemological Institute of America (GIA) uses a grading system to assess diamond clarity, which ranges from Flawless (no inclusions visible under 10x magnification) to Included (inclusions visible to the naked eye). Lab grown diamonds with fewer or no inclusions will typically command a higher price because they are rarer and more visually appealing. On the other hand, diamonds with noticeable inclusions may be more affordable, making them a more budget-friendly option for some buyers.
Identifying Inclusions in Lab Grown Diamonds
Gemologists use specialized tools to identify and assess inclusions in lab grown diamonds. These tools include magnification instruments such as microscopes and loupes, which allow gemologists to examine the diamond closely. Inclusions are often graded based on their size, location, and visibility. Diamonds with small inclusions that are not visible to the naked eye are considered higher in value than diamonds with large inclusions that can be easily seen. However, even diamonds with noticeable inclusions can still have value, especially if the inclusions are strategically placed in a way that does not significantly affect the overall appearance of the diamond.
Choosing a Lab Grown Diamond with Inclusions
When choosing a lab grown diamond, it’s important to consider the inclusions present in the stone. Buyers should evaluate the type, size, and visibility of the inclusions, as these factors will affect the diamond’s overall appearance and value. Some buyers prefer diamonds with inclusions because they offer a unique, personal touch. Others may prioritize clarity and opt for a diamond with fewer inclusions for a more flawless look. Regardless of your preference, understanding the role of inclusions in lab grown diamonds can help you make a more informed decision when purchasing a diamond.
Conclusion
Inclusions in lab grown diamonds are an essential factor to consider when purchasing a diamond. They can influence the diamond’s clarity, appearance, and value. While inclusions may be seen as imperfections, they are a natural characteristic of diamonds, whether they are lab grown or mined. By understanding the different types of inclusions, how they form, and their impact on the value of a diamond, buyers can make a more informed decision when choosing the perfect lab grown diamond. Whether you choose a diamond with minimal inclusions or one with unique imperfections, you can rest assured that your lab grown diamond is just as beautiful and durable as a natural diamond.
