Lab-grown diamonds, also known as man-made or synthetic diamonds, are created using two different methods: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD).
HPHT diamonds are formed through a process similar to the natural diamond formation.
CVD diamonds are created through the interaction of chemical components.
7 Key Differences Between Lab-Grown and CVD Diamonds
1. Origin
One of the main differences between lab-grown and mined diamonds is their origin.
Lab-grown diamonds are created in controlled laboratory environments.
Mined diamonds are extracted from the Earth.
2. Cost
This difference in origin also affects their cost.
CVD diamonds are generally cheaper than mined diamonds.
Lab-grown diamonds are 40 to 60% less expensive.
Despite the lower cost, CVD diamonds provide the same brilliance, fire, and sparkle as mined diamonds.
3. Ethical Aspect
Another significant difference is the ethical aspect.
Lab-grown CVD diamonds are considered ethical because they are created in safe environments and their source is known.
Mined diamonds, on the other hand, may have origins in conflict mines, which can cause harm or threat to human life and the environment.
Lab-grown diamonds follow labor regulations and do not contribute to unethical practices associated with mined diamonds.
4. Quality
In terms of quality, CVD diamonds undergo the same certification process as mined diamonds.
After the growth process, qualified diamond certification labs measure and assess the color, cut, clarity, and carat (the 4 Cs) of CVD diamonds.
Each diamond is given an overall grade based on these factors.
While the average CVD diamond is likely to have a higher grade than the typical mined diamond, there is still a range of quality in CVD diamonds due to the similarity of the processes involved in natural diamond formation.
5. Pros of CVD Diamonds
Pros of CVD diamonds include their sparkle, fire, and brilliance.
They are available in different shapes, sizes, and colors.
The growth time is shorter (6-8 weeks).
They have a lower environmental impact compared to mined diamonds.
Additionally, CVD diamonds do not originate from conflict areas, making them free from ethical concerns related to blood diamonds.
6. Cons of CVD Diamonds
However, there are also some cons to consider.
There are no specific regulations or specifications for CVD diamonds, making it difficult to determine the exact quality of what you are getting.
CVD diamonds are not widely available, and some renowned jewelry brands may refuse to sell them.
Additionally, CVD diamonds do not come with GIA certification, which is a widely recognized certification for mined diamonds.
7. Cost
In terms of cost, CVD diamonds are generally priced 20-30% lower than naturally sourced diamonds.
This price difference can be attributed to the high costs involved in mining, the supply chain of mined diamonds, and price manipulation in the mined diamond market.
