What are Lab Grown Diamonds and How are They Made?

Lab grown diamonds, also known as synthetic diamonds or laboratory grown diamonds, are man made gems that possess the same chemical and physical properties as natural diamonds. They are created through a controlled process in a laboratory environment. In this blog, we will survey what lab grown diamonds are and how they are made.

What are Lab Grown Diamonds?

Lab grown diamonds are diamonds that are produced in a laboratory instead of being formed naturally in the Earth's crust. They have the same crystal structure, chemical composition, and optical properties as natural diamonds. The main difference lies in their origin natural diamonds are created deep within the Earth over millions of years, while lab grown diamonds are grown in a matter of weeks or months using advanced technology.

How are Lab Created Diamonds Made?

There are two primary methods used to create lab created diamonds: High Pressure, High Temperature (HPHT), and Chemical Vapor Deposition (CVD).

High Pressure, High Temperature (HPHT) Method

In the HPHT method, a small diamond seed, typically a natural diamond fragment or a lab grown diamond, is placed in a chamber. The chamber is then subjected to intense heat and pressure that mimic the conditions deep within the Earth where natural diamonds form. A carbon source, such as graphite, is also present in the chamber. Under these conditions, the carbon atoms dissolve in the molten metal and crystallize around the diamond seed, causing it to grow layer by layer. This process is carefully controlled to ensure the growth of a high quality diamond.

Chemical Vapor Deposition (CVD) Method

The CVD method involves placing a diamond seed in a sealed chamber filled with hydrocarbon gases, such as methane. The chamber is then heated to create a plasma environment. The hydrocarbon gases break down into carbon atoms, which are then deposited onto the diamond seed, causing it to grow. The carbon atoms layer upon the seed over time, forming a larger diamond. This process allows for precise control of the diamond's growth and enables the creation of high quality diamonds.

Advantages of Lab Created Diamonds

Lab created diamonds offer several advantages over natural diamonds:

• Cost:  Lab created diamonds are generally more affordable than natural diamonds of comparable quality. The controlled production process reduces the costs associated with mining and sourcing natural diamonds.

• Ethical Considerations: Lab grown diamonds are conflict free, as they are produced in a controlled environment and do not contribute to unethical mining practices. They offer a socially responsible alternative for those concerned about the origin of their diamonds.
• Environmental Impact: Diamond mining can have a significant environmental impact, including habitat disruption and pollution. lab grown diamonds have a smaller ecological footprint, making them a more sustainable choice.

Lab grown Diamonds vs. Natural Diamonds: Understanding the Differences

Lab created diamonds have long been adulated for their beauty and rarity. Lab-grown diamonds instead of natural diamonds have given the diamond industry a new and modern impetus for discussion. In this article, we will compare lab grown diamonds and natural diamonds, discuss the concept of the best lab created diamonds, and delve into the world of laboratory grown diamonds.

Natural Diamonds

 Origin:

Natural diamonds are formed deep within the Earth's mantle over billions of years under extreme heat and pressure. On the other hand, lab grown diamonds are created in controlled laboratory environments using advanced technology.

Composition and Structure

Both lab grown and natural diamonds have the same chemical composition pure carbon and possess the characteristic crystal structure of diamonds. From a chemical and physical standpoint, lab grown diamonds are virtually identical to natural diamonds.

Availability and Supply

Natural diamonds are finite resources that are mined from the Earth. Their availability and supply are dependent on geological factors and the mining industry. In contrast, lab grown diamonds can be produced in larger quantities and provide a more consistent supply since they are created in laboratories.

Quality and Grading:

Lab grown diamonds undergo the same quality assessments and grading processes as natural diamonds. Gemological laboratories, such as the Gemological Institute of America (GIA), evaluate lab grown diamonds using the same criteria known as the "Four Cs": carat weight, color, clarity and cut as they do for natural diamonds.

Best Lab Created Diamonds

When comes to the best choice of the lab-created diamond, several elements come as the first primacy.

• Quality: The lab grown diamonds quality is the first and high element. A lab-created diamond quality has determined with their color, clarity, cut. The closer a lab grown diamond's attributes align with those of a high quality natural diamond, the more desirable it is considered.
• Certification: Reputable lab grown diamond manufacturers provide grading reports from independent Gemological laboratories, such as the GIA or the International Gemological Institute (IGI). These reports certify the quality and authenticity of the lab grown diamond.
• Personal Preferences: Beauty is subjective, and individual preferences for color, size, and shape play a significant role in determining the best lab created diamond for a person. What may be ideal for one individual might not be the same for another.

Laboratory Grown Diamonds

The term "laboratory grown diamonds" encompasses diamonds created using various methods, such as High-Pressure, High Temperature (HPHT), and Chemical Vapor Deposition (CVD). Both methods stimulate the natural diamond-growing process but with controlled conditions in a laboratory setting.

High-Pressure, High-Temperature (HPHT) Method

In the HPHT method, a diamond seed is subjected to high pressure and high temperature, allowing carbon to dissolve and crystallize around the seed, resulting in a larger diamond.

Chemical Vapor Deposition (CVD) Method

The CVD method involves the deposition of carbon atoms onto a diamond seed in a plasma environment created by hydrocarbon gases. Over time, the carbon atoms accumulate, leading to the growth of a diamond.

Lab grown diamonds possess several notable features that make them distinct and appealing. Here are some features of lab-grown diamonds:

• Chemical and Physical Properties: Lab-grown diamonds have the same chemical framework as natural diamonds, consisting of pure carbon systematized in a crystal lattice structure. They define identical physical properties, including hardness, refractive index, and thermal conductivity. This ensures that lab grown diamonds possess the same brilliance, fire, and durability as natural diamonds.
  
• Clarity and Color Options: Lab grown diamonds offer a wide range of clarity and color options. They can be found in various grades of clarity, from flawless to included, and in a spectrum of colors, including colorless, near-colorless, and fancy colored diamonds.
