Lab Diamonds - Engagement Rings Buyers Guide

WRD icon

Lab diamonds have been on an extraordinary journey, soaring in popularity over the last decade. As laboratory techniques have advanced and production has surged, so too has the appeal of these exceptional stones. But what exactly are lab diamonds? Are they as ethical as they're touted to be? And should you consider them for your engagement ring? We've delved into the depths of research so that you can make an informed choice.


What Are Lab Diamonds?


Lab diamonds are, in every chemical and physical sense, identical to their naturally mined counterparts. The sole distinction lies in their creation process. Two primary methods bring these gems to life:

  • High Heat and Pressure: This classic technique involves subjecting carbon to extreme heat and pressure until it crystallises into a diamond.
  • Chemical Vapour Deposition (CVD): A more recent method, CVD creates an environment where carbon atoms are drawn to another substance. Gradually, these carbon atoms layer upon each other, forming a diamond.


While you may come across terms like "synthetic diamonds" or "lab-grown diamonds," be cautious of the term "diamond simulants." This term refers to what are essentially fake diamonds made from non-diamond materials. To ensure you're investing in true lab diamonds, watch out for these distinctions when shopping.

Are Lab Diamonds Ethical?

The ethical landscape of lab-created diamonds is multifaceted, much like that of naturally mined diamonds. There are clear advantages to choosing lab diamonds:

  • Environmental Impact: Lab diamonds spare the Earth from the deforestation and environmental devastation associated with diamond mining.
  • Conflict-Free: Lab diamonds are inherently free from any conflict associations, providing peace of mind to conscientious consumers.

However, it's essential to recognize that the term "lab" can be somewhat misleading. Lab diamonds do require energy to produce, which can have environmental consequences. 


Both lab-grown and natural diamonds have their ethical pros and cons, and the choice between them ultimately depends on which set of pros aligns more closely with your values.

Natural Mined Diamonds vs. Lab-Created

So, why opt for a lab diamond over a naturally mined one? There are several compelling reasons:

  • Cost-Effective: Lab-grown diamonds tend to be approximately 20% more affordable than mined diamonds, making them an attractive option for budget-conscious buyers.
  • Exceptional Quality: Lab diamonds often exhibit ideal colour and clarity, as they don't develop natural inclusions that occur due to varying conditions during formation.
  • Diverse Colours: Many lab-grown diamonds are available in rare fancy colours, allowing you to find your dream ring, even if it's a vibrant pink one like J.Lo's.
  • Conflict-Free: Lab diamonds guarantee that your ring has not contributed to habitat destruction through mining.

On the other hand, natural diamonds have unique characteristics:

  • Value Retention: Natural diamonds can hold or increase in value over time, particularly if they possess exceptional colour and clarity. Grading certificates add to their value.
  • Rare Geological History: Natural diamonds boast a remarkable geological history, often predating the age of dinosaurs. Wearing one is a privilege, as it carries such geological significance.
  • Ethical Options: The Kimberley Process ensures that mined diamonds in countries adhering to it are conflict-free. Ethical, natural diamonds are readily available.
