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.


Q1) What is a Diamond? 

Diamond is a rare, naturally occurring mineral composed entirely of carbon. Each carbon atom in a diamond is surrounded by four other carbon atoms and connected to each of them by strong covalent bonds - the strongest type of chemical bond. This simple, uniform, tightly-bonded arrangement yields one of the most durable and versatile substances known.
