Prime Minister recently gifted an eco-friendly lab-grown 7.5 carat diamond, , to the US First Lady Jill Biden.
About Lab-Grown Diamonds:
- Lab-grown diamonds are diamonds that are produced using specific technology which mimics the geological processes that grow natural diamonds.
- The diamond simulants such as Moissanite, Cubic Zirconia (CZ), White Sapphire, YAG, and others are used to make them look like natural diamonds.
- How are LGDs produced? There are multiple ways in which LGDs can be produced.
- High pressure, high temperature” (HPHT) method:
- It is the most common and cheapest method.
- In this method, extremely heavy presses that can produce up to 730,000 psi of pressure under extremely high temperatures of at least 1500 celsius are applied.
- Usually, graphite is used as the “diamond seed” and when subjected to these extreme conditions, the relatively inexpensive form of carbon turns into one of the most expensive carbon forms.
- Chemical Vapor Deposition (CVD) and explosive formation create what is known as detonation nanodiamonds.
- Application of Lab-grown diamonds:
- Used for industrial purposes, in machines and tools and their hardness and extra strength make them ideal for use as cutters.
- Pure synthetic diamonds are used in electronics as a heat spreader for high-power laser diodes, laser arrays and high-power transistors.
Hence both statements are correct.

Introduction:
Lab-grown diamonds are diamonds that are created in a laboratory using advanced technology. They possess the same physical and chemical properties as natural diamonds, but are produced in a controlled environment. In this response, we will analyze the given statements regarding lab-grown diamonds and provide an explanation for the correct answer.
Statement 1: They are produced using specific technology which mimics the geological processes that grow natural diamonds.
Explanation:
Lab-grown diamonds are created using a process called Chemical Vapor Deposition (CVD) or High Pressure High Temperature (HPHT) method. In the CVD method, a diamond seed is placed in a chamber and a mixture of carbon-rich gases is introduced. These gases are then heated to extreme temperatures, causing the carbon atoms to form a diamond lattice on the seed. This process closely mimics the natural environment where diamonds are formed deep within the Earth's mantle.
Similarly, in the HPHT method, a small diamond seed is placed in a press and subjected to high pressure and temperature conditions, allowing carbon atoms to bond and form a diamond. Again, this process replicates the geological conditions under which natural diamonds are formed.
Hence, statement 1 is correct.
Statement 2: The Diamond simulants such as Moissanite and White Sapphire are used to make them look like natural diamonds.
Explanation:
Diamond simulants are materials that resemble diamonds but have different chemical compositions and physical properties. Moissanite and White Sapphire are commonly used as diamond simulants. However, lab-grown diamonds are not made by using diamond simulants.
Lab-grown diamonds are created by growing actual diamond crystals using carbon atoms. The process involves the deposition of carbon atoms onto a diamond seed or the formation of diamond crystals under high pressure and temperature. These lab-grown diamonds possess the same optical and physical properties as natural diamonds and can only be differentiated through specialized testing.
Therefore, statement 2 is incorrect.
Conclusion:
In conclusion, statement 1 is correct as lab-grown diamonds are produced using specific technology that mimics the natural geological processes that grow natural diamonds. On the other hand, statement 2 is incorrect as lab-grown diamonds are not made by using diamond simulants like Moissanite or White Sapphire.
