Understanding the diamond industry

In fine jewellery, diamonds represent the pinnacle of luxury and romance, notably when featured in engagement rings.

A thorough understanding of diamonds covers their inherent properties and the difference between their natural and synthetic counterparts.

Natural vs lab-grown diamonds

One finds natural diamonds deep within the Earth, where high pressure and temperatures crystallise carbon over billions of years. They are then mined, cut, and polished before reaching the market.

Lab-grown diamonds, also known as synthetic or artificial diamonds, are created in a controlled laboratory setting using technologies such as High-Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). These processes imitate nature’s conditions to produce diamonds at a quicker rate.

Natural diamonds:

  • Formed over 1-3 billion years
  • Extracted through mining operations

Lab diamonds:

  • Created within weeks to months
  • Produced using HPHT or CVD

The debate regarding ethics primarily focuses on the environmental impact and the human cost of natural diamond mining versus the lower ecological footprint of laboratory creations.
