First of all, lab-grown diamonds are just as real as diamonds mined from the earth. Lab-grown diamonds are identical in every way to diamonds mined from the earth, except that they were grown in a lab. They have the same chemical, physical, and optical properties as mined diamonds, and when cut, they exhibit the same fire, sparkle, and brilliance.
The Future of Lab Grown Diamonds
A few years ago it was uncertain, but now it is clear: lab-grown diamonds are here to stay. This is due to two main reasons:
Price
Lab-grown diamonds cost on average 50% less than mined diamonds. This makes them attractive to people who might not otherwise be able to purchase a diamond. It also offers an affordable alternative for those who want to consciously choose a more ethical and environmentally friendly option.
Ecological Footprint
The production of lab-grown diamonds has a much smaller ecological footprint than mining natural diamonds. By some estimates, the environmental impact of lab-grown diamonds is up to 13 times smaller. This makes them particularly attractive to Millennials and the emerging Gen-Z, who increasingly value sustainability and eco-friendliness.
Preferences and Perceptions
Despite the advantages of lab-grown diamonds, many people still prefer natural diamonds. Surveys show that most women still opt for ‘the real thing’ when given the choice. This may be due to the perception of value and rarity that is still strongly associated with natural diamonds.
Production methods
There are two main methods of producing lab-grown diamonds:
HPHT-proces (High Pressure High Temperature)
This process simulates the natural growth environment of diamonds by using a large press that generates temperatures of around 1400 degrees Celsius and pressures of 6 GPa. This process mimics the conditions found deep within the earth, where natural diamonds are formed.
CVD (Chemical Vapour Deposition)
This method breaks down carbon-rich gases using a microwave plasma. The free carbon is then forced to crystallize as diamond on the substrates at the bottom of the reactor. This process offers more control over the quality and properties of the diamonds produced.
Conclusion
Lab-grown diamonds offer an affordable and environmentally friendly alternative to natural diamonds. They are chemically, physically and optically identical to natural diamonds, with the same brilliance and sparkle. Their lower price and smaller carbon footprint make them an attractive option for a wide range of consumers. While perceptions of value and rarity still play a role in the preference for natural diamonds, it is clear that lab-grown diamonds will have a lasting impact on the diamond market.
