Many times, you look at a diamond and are fascinated by its beauty. Well, diamonds are made to be admired, not only for their brilliance but also for the value they hold. There are a variety of diamonds available in the market, but only lab-grown and natural diamonds are real. Other options, such as moissanite and cubic zirconia, which look similar to diamonds and once took the jewellery industry by storm, are not diamonds at all.

While we look back on history, no one would imagine recreating something similar to a diamond, but with technological advancement, it did come true. The concept of CVD diamonds broke out. The invention is not new, but still, many have not accepted it. This brief note regarding CVD and natural diamonds will highlight the understanding of diamonds.

What are CVD diamonds?
When CVD diamonds (chemical vapor deposition) were first introduced, many mistaken them for duplicates and fake diamonds. They also didn’t get much acceptance from people. This might be due to a lack of information or proper knowledge about CVD diamonds and myths regarding them, i.e, the myth that they do not hold value and are not as real as natural diamonds.

To understand the concept, let's dive into the brief meaning of CVD diamond.
What are CVD diamonds?? CVD diamonds are a recent development in lab-grown diamond production. This technique creates diamonds by depositing carbon atoms onto a substrate in a low-pressure environment of lab-grown, which are real diamonds, created in an artificial environment under specialized care with the same carbon crystallization process as mined diamonds. These diamonds are genuine in every sense. For every diamond to be called a genuine diamond, it must possess the 4Cs: clarity, color, carat, and cut. 

While Natural diamonds are mined from the core of the earth, which is formed after billions of years. from unethical mining to environmental degradation, natural diamonds have surrounded themselves with multiple controversies , sparked a global renouncement of natural diamonds which then led to a significant decrease in their demand in the last decade among socially and environmentally conscious consumers. As a result, the demand for ethical and environmentally friendly alternatives such as CVD diamonds has risen significantly.

Common facts about CVD and natural diamonds:

Parameters Natural diamonds CVD diamonds
Chemical Pure carbon arranged in a cubic crystal structure. Pure carbon arranged in a cubic crystal structure.
Physical High brilliance and shine. High brilliance and shine.
Hardness 10 on the Mohs hardness scale. 10 on the Mohs hardness scale.
Transparency Extremely transparent with high brilliance and dispersion. Extremely transparent with high brilliance and dispersion.
Durability Extremely durable, the hardest stone on earth. Extremely durable, the hardest stone on earth.
Color Colorless, bright, and radiant. Colorless, bright, and radiant.
Cut Skilled craftsmanship and high-quality cut. Skilled craftsmanship and high-quality cut.
Carat Weight determines the value along with other factors such as cut and clarity. Weight determines the value along with other factors such as cut and clarity.
Impurities Can contain a variety of impurities. Can contain impurities but very limited.

Hence both natural and CVD diamonds are more alike and possess similar characteristics.

Difference between them:

Parameters Natural diamonds CVD diamonds
Formation Such diamonds are formed within the earth's core. Such diamonds are formed within the earth's core.
Time duration Natural diamonds take billions of years to form naturally under the core of the earth. Natural diamonds take billions of years to form naturally under the core of the earth.
Extraction process the natural diamonds are extracted by the process of deep mining. the natural diamonds are extracted by the process of deep mining.
Environmentally friendly The process of deep mining consequently affects the environment at large. The CVD diamonds are environmentally friendly as they do not harm the environment to such an extent.
Sustainable approach Such diamonds are scarce and non-renewable resources. The approach of CVD diamonds is sustainable and eco-friendly.
Expensive Natural diamonds are very expensive and rare. CVD diamonds are affordable and accessible to all.

The economic value of CVD:
The myth that CVD diamonds hold no value for the long term is being spread at large in the market among buyers, it is as untrue as the myth that eating seeds can grow a plant inside your stomach. just like eating seeds has no connection to growing plants inside your stomach, the diamond's value is not determined based on its formation but according to the 4cs. Hence, the CVD diamonds hold their value for the long term without jeopardizing their quality.

How to value a CVD diamond:
Every diamond is given certificates from IGI, GIA, and many other reputed institutes based on its 4cs color, carat, clarity, and cut.  This certificate bears the guarantee of authenticity and quality while ensuring the diamond meets its highest industrial standards. 




The clearer the diamond, the higher its value. Thus, the CVD diamond value is determined majorly by its clarity:

High values for higher clarity grades such as FL (flawless), IF (internal flaw), and VVS1/VVS2 (very very slightly included) are extremely rare and command premium prices.

Whereas the lower clarity grades such as SI1 and I1 are more affordable than above-graded diamonds.

Tips to follow for the actual valuation of diamonds:

  • - Always purchase from legitimate sellers either online or offline.
  • - Analys the concept of 4Cs: color, carat, cut and clarity.
  • - Do ask for bills and certificates of diamonds (must be from reputed institutes) from the seller. 
  • - Cross-verify the diamond price from the certificates based on clarity & color i.e VVS1, IF, D, or F colored.
  • - Do verify the guarantee, warranty, and buy-back policy.
  • - Do verify the terms and conditions and other policies. 

Conclusion:

The CVD invention is considered to be the most affordable invention of mankind as it provides the perfect blend of brilliance at the same time saving the environment & pocket. As it is crystal clear from the above exploration about the diamond world, the diamonds formed in laboratories or earth cores are alike with no difference at all except saving our beloved Mama Earth.
