What is a Lab-Grown Diamond?
The Ultimate Guide to Know Yours Before Getting One
In the market for diamond jewelry?
Before spending your lifetime savings, it's essential to learn about the best alternatives - lab-grown diamonds.
Lab grown diamonds are gemstones created in controlled environments using advanced technologies that mimic the natural processes of diamond formation. Appearing in a wide range of sizes and shapes, these perfectly identical stones are gaining popularity in the mined diamond-dominant jewelry industry.
Renowned for their elegance, affordability, and environmentally friendly nature, lab-grown diamonds are an excellent choice for modern consumers who care about sustainability. Although there is a lot to know, to help you answer the question, What are Lab-grown diamonds? We will cover all the information you need to know.
How Does a Lab-Diamond Form?
As discussed, lab-grown diamonds—also called cultured diamonds—are created in the lab using advanced methods that imitate how diamonds naturally form on the Earth. Made from carbon and structured in a crystal formation, these diamonds exhibit the same strength and dazzling shine as their natural equivalents.
These diamonds are chemically, physically, and visually identical to their natural companions, offering the same brilliance and durability.
Methods used for creating Lab-grown diamonds:
HPHT (High Pressure, High Temperature)
This process replicates the high-pressure and temperature environment of the Earth under which natural diamonds form. In this process, a diamond seed is planted in carbon and exposed to high pressure and heat inside a machine. It allows carbon to crystallize around the diamond seed and form a larger diamond over weeks or months.
CVD (Chemical Vapor Deposition)
CVD method uses a chamber filled with gases such as methane and hydrogen. These gases are energized—typically with microwave energy—causing them to break down and deposit layers of carbon on a diamond seed. This method allows for greater precision and is often used for creating larger diamonds.
Both techniques provide the natural conditions under which diamonds form on the Earth, ensuring that the diamonds are chemically, physically, and visually equivalent to mined diamonds, only more sustainable.
The Step-by-Step Making of Lab-Grown Diamond Creation
1. Diamond Seed
This is the initial stage for creating a lab-grown diamond. A small piece of diamond, often called a diamond seed, is used to help begin the growth process. It provides a foundation on which the new diamond can form.
2. Exposure to Heat and Pressure or Carbon Gas:
Depending on the method, the diamond seed is then subjected to either extreme heat and pressure or exposed to carbon gas:
HPHT Method: The diamond seed is placed in a chamber, surrounded by carbon. It's then subjected to extremely high pressure (around 1.5 million pounds per square inch) and high temperatures (over 1,400 degrees Celsius). This process imitates the natural conditions deep within the Earth where natural diamonds form.
CVD Method: In this approach, the diamond seed is placed in a vacuum chamber filled with hydrogen and methane gases. The gases have been energized (often with microwaves), causing them to break apart and deposit carbon atoms onto the seed, layer by layer.
3. Crystal Growth
With time, either HPHT or CVD, carbon atoms begin to crystallize around the diamond seed. This process can take weeks to months as the diamond grows and takes on its desired shape. The result is a diamond with the same properties as a naturally occurring one.
4. Cutting and Polishing Process
Once the diamond has grown, it is carefully cut and polished. Skilled artisans shape diamonds to enhance their shine and sparkle. Just like natural diamonds, lab-grown stones are shaped to maximize their sparkle and beauty for jewelry settings.
This entire process results in a lab-grown diamond that mirrors the qualities of natural diamonds but with added benefits—eco-friendliness and affordability.
Lab-Grown Diamonds vs. Natural Diamonds
1. Visual Differences:
To the naked eye, lab-created and natural diamonds can be nearly impossible to distinguish. Both display the same brilliance, fire, and sparkle. Without specialized equipment, it can be challenging to identify which is which.
2. Chemical and Physical Properties:
Both types of diamonds are composed of pure carbon and share identical chemical, physical, and optical properties. They rank a 10 on the Mohs scale, making them equally durable for everyday use.
3. Price Comparison:
Lab-grown diamonds cost significantly less. With no mining involved and reduced production expenses, lab-created stones offer excellent value.
4. Environmental & Ethical Impact:
Lab-grown diamonds are often considered environmentally friendly, as their production does not involve any ecological disturbance associated with diamond mining. Additionally, they provide a conflict-free alternative, reducing concerns about unethical sourcing.
5. Resale & Value:
Natural diamonds generally hold value better than lab-grown diamonds, often appreciating over time. Lab-grown diamonds may not have the same resale market, and their long-term value can be less as they become more widely available.
6. Heritage and Sentiment:
While lab-grown diamonds have gained popularity, there is still a strong charm surrounding natural diamonds. Many people value the rarity and history of natural stones, which contributes to their perceived prestige. However, awareness and acceptance of lab-grown diamonds are steadily increasing.
How to Choose the Right Lab-Grown Diamond for You
Choosing a lab-grown diamond involves considering several important factors. Here's a simplified process to help you make the best decision.
1. Understand the 4 Cs:
- Cut: This affects how well the diamond reflects light. Opt for an excellent or ideal cut for maximum brilliance.
- Color: Lab-grown diamonds come in various colors. Most prefer near-colorless diamonds (G-H) for their classic look.
-Clarity: This refers to the presence of inclusions or flaws. Look for diamonds with at least SI1 clarity for a good balance between quality and cost.
- Carat: Consider the size that fits your style and budget. Remember that carat weight affects the price significantly.
