Difference Between Lab Diamond and Natural Diamond (Explained)

Lab-grown diamonds have been gaining popularity as a viable alternative to natural diamonds. These diamonds are real and created in controlled laboratory settings using techniques like Chemical Vapor Deposition (CVD) or High Pressure High Temperature (HPHT). They possess the same physical and chemical properties as natural diamonds and are even certified by reputable institutions like the Gemological Institute of America (GIA). Visually, lab-grown diamonds are indistinguishable from natural ones and are graded on the same scales for color, clarity, and cut. The main distinction between the two lies in their origin and price. Lab-grown diamonds are manufactured in labs, while natural diamonds are formed over millions of years under the Earth’s crust. Additionally, lab-grown diamonds are significantly more affordable, offering consumers a more budget-friendly option.

Key Takeaways:

  • Lab-grown diamonds are real diamonds created in a controlled laboratory environment.
  • They have the same physical and chemical properties as natural diamonds.
  • Lab-grown diamonds are visually indistinguishable from natural diamonds.
  • They are graded on the same scales for color, clarity, and cut.
  • The main difference is their origin and price – lab-grown diamonds are created in labs and are more affordable compared to natural diamonds.

How Lab Grown Diamonds are Made

Lab Grown Diamonds are created using two popular methods: Chemical Vapor Deposition (CVD) and High Pressure High Temperature (HPHT). In the CVD process, a small diamond seed is placed in a chamber filled with heated gases. Layers of carbon form on the seed, resulting in the growth of a diamond crystal. In the HPHT process, natural graphite is subjected to extreme pressure and temperature, mimicking the conditions under which natural diamonds are formed. Both methods produce diamonds that are chemically and physically similar to natural diamonds. The difference between CVD and HPHT diamonds cannot be seen with the naked eye, and both are graded using the same 4 Cs: color, cut, clarity, and carat.

To better understand the process, let’s take a closer look at each method:

CVD (Chemical Vapor Deposition) Diamonds

In the CVD process, a diamond seed is placed in a chamber filled with a mixture of hydrogen and carbon-containing gases. These gases are then heated to extreme temperatures, causing the carbon atoms to break down and form a plasma. The carbon atoms then settle onto the diamond seed, layer by layer, until a complete diamond crystal is formed. This method allows for greater control over the growth process, resulting in high-quality diamonds with excellent clarity and color.

HPHT (High Pressure High Temperature) Diamonds

In the HPHT process, natural graphite is placed in a pressure vessel and subjected to extreme heat and pressure. The combination of these factors causes the graphite to transform into diamond over time. This method closely replicates the conditions under which natural diamonds are formed deep within the Earth’s mantle. The resulting diamonds have similar physical and chemical properties to natural diamonds and can be cut and polished just like their mined counterparts.

Both CVD and HPHT diamonds offer a sustainable alternative to natural diamonds, as they are created in a controlled environment without the need for mining. They also provide consumers with a wider range of options in terms of size, shape, and color. Whether you choose a CVD or HPHT diamond, you can be confident that you are getting a real diamond with all the beauty and brilliance of a natural stone.

Table: Comparison of CVD and HPHT Diamonds

CVD Diamonds HPHT Diamonds
Formation Method Chemical Vapor Deposition High Pressure High Temperature
Origin Laboratory-grown Laboratory-grown
Physical Properties Similar to natural diamonds Similar to natural diamonds
Clarity Excellent Excellent
Color Range of options Range of options
Availability Increasing Increasing
Price Lower than natural diamonds Lower than natural diamonds

As you can see, both CVD and HPHT diamonds have their own unique advantages. The choice between the two ultimately depends on your personal preferences and budget. Whichever method you choose, rest assured that lab grown diamonds are an ethical and sustainable choice that offers the same beauty and quality as natural diamonds.

Pros and Cons of Lab Grown Diamonds

Lab Grown Diamonds have gained popularity in recent years due to their unique advantages. Here, we will discuss the pros and cons of lab grown diamonds compared to natural diamonds.

Pros of Lab Grown Diamonds

  • Affordability: Lab grown diamonds are typically 30-50% less expensive than natural diamonds. This allows consumers to purchase larger and more dazzling diamonds within their desired budget.
  • Ethicality: Lab grown diamonds are considered more ethical as they are not mined, reducing the environmental impact and potential for conflict diamonds. They have a clear chain of custody, ensuring their origins and avoiding any ethical concerns.

Cons of Lab Grown Diamonds

  • Resale Value: Lab grown diamonds may not hold their resale value as well as natural diamonds due to their abundance in the market. This is something to consider for those who may plan to sell or upgrade their diamond in the future.
  • Romantic Appeal: Some individuals question the romantic aspect of lab grown diamonds, as they are not formed naturally over millions of years. This may be a consideration for those who value the sentimental value and symbolism associated with natural diamonds.

In summary, lab grown diamonds offer affordability and ethicality, making them an attractive option for many consumers. However, factors such as resale value and romantic appeal may be important considerations for individuals when choosing between lab grown and natural diamonds.

GIA and IGI Certified Lab Grown Diamonds

When shopping for lab grown diamonds, it is important to look for certification from reputable institutions like the Gemological Institute of America (GIA) and the International Gemological Institute (IGI). These certifications provide assurance to consumers about the quality, authenticity, and value of the lab grown diamond they are purchasing.

GIA-certified lab grown diamonds undergo a rigorous grading process to evaluate their color, clarity, and cut. The certification ensures that the lab grown diamond meets the same standards as natural diamonds in terms of its physical and chemical properties. Each GIA-certified lab grown diamond is assigned a unique number that is inscribed on the diamond, providing a clear chain of custody and confirming its certification details.

Similarly, IGI-certified lab grown diamonds are also highly regarded in the jewelry industry. The certification from IGI guarantees that the lab grown diamond meets the highest standards of quality and authenticity. IGI-certified lab grown diamonds are evaluated based on their cut, color, clarity, and carat weight, ensuring that consumers can make an informed decision when purchasing these diamonds.

The Importance of Diamond Certification

Having a certification from GIA or IGI for lab grown diamonds is crucial for several reasons. Firstly, it provides peace of mind to consumers that they are getting a genuine and high-quality lab grown diamond. The certification ensures that the diamond has been thoroughly analyzed and graded by experts in the field, giving consumers confidence in their purchase.

Secondly, a certified lab grown diamond holds its value and can be easily identified in the future. With the unique certification number and laser inscription, the origin and characteristics of the diamond can be traced back, making it easier to sell or trade in the future. The certification acts as a guarantee of the diamond’s quality and authenticity, making it a valuable asset.
