Lab-Grown Diamonds (LGD):
- These are diamonds created in a laboratory, and they share the same chemical composition and physical and optical properties as natural diamonds.
- Usually, Graphite is used as the seed to create LGD.
Formation Process
Created in a laboratory using high-pressure, high-temperature (HPHT), or chemical vapor deposition (CVD) methods.
Environmental Impact
- Generally considered more environmentally friendly as they require fewer resources and land compared to mining.
Ethical Considerations
- Conflict-free and avoid supporting unethical mining practices, such as human rights violations.
Utility for India:
- LGD would not impact India’s established diamond industry because similar processes of polishing and cutting are required for LGD as well.
Applications:
- LGDs are useful for many industrial purposes due to their hardness and strength. They’re perfect for machines, tools, and cutters.
- Pure synthetic diamonds also play a role in electronics, where they’re used to dissipate heat in high-power laser diodes, laser arrays, and transistors.
Environmental Impact:
- Producing LGDs is more environmentally friendly than mining natural diamonds.
- It takes almost ten times more energy to mine a natural diamond than to create a lab-grown one.
Why in News:
Indian Prime Minister Narendra Modi recently gifted a 7.5-carat lab-grown diamond, also known as green diamond to US First Lady Jill Biden on his visit to the USA.
