Do Lab Grown Diamonds Fade?

Dispelling myths and presenting the truth, we’ll explore the world of diamond creation in the laboratory and within the earth to provide a balanced comparison. The main aim of this blog is to address any uncertainties or queries, particularly on whether or not lab-grown diamonds are prone to fading over time.

Understanding Lab-Grown Diamonds

Lab-grown diamonds are produced in a controlled environment as opposed to created over thousands of years in the earth’s crust. The process of creating a lab-grown diamond involves either High-Pressure High-Temperature (HPHT) or Chemical Vapor Deposition (CVD), methods that mimic the natural conditions they’re traditionally formed in. Lab-grown diamonds develop their structure from a small seed crystal over time, resulting in a chemically, physically, and optically identical to a natural diamond.

The Myth Of Fading Diamonds

Currently, a common myth suggests lab-grown diamonds may fade over time, particularly in comparison to their natural counterparts. This misconception likely stems from a mix-up with diamond simulants such as cubic zirconia, which indeed can deteriorate and lose their shine with wear. By contrast, both lab-created and earth-mined diamonds consist of carbon atoms meticulously arranged in a diamond crystal lattice. This intricate structure endows them with exceptional durability and resistance, effectively debunking the myth that they will fade over time.

Why Don’t Lab Diamonds Fade?

The process of creating diamonds in a laboratory environment ensures that these gems embody the same enduring properties as their natural equivalents. The lab cultivation mirrors the environmental conditions under which earth-mined diamonds form, thereby giving lab-grown diamonds a robust structure that promises longevity. This technological marvel means that lab-grown diamonds, much like their natural counterparts, are destined to retain their captivating brilliance for generations.

What Influences Diamond Durability?

The durability of a diamond, be it lab-grown or naturally mined, is determined by its inherent crystal structure. Known as the hardest natural substance on Earth, diamonds possess unparalleled resilience. However, their endurance isn’t invulnerable. Factors like exposure to harsh chemicals or extreme physical impacts can potentially compromise their structure and impact their longevity.

Therefore, providing proper care for your diamond engagement ring is crucial. By doing so, you maintain its appearance and ensure its enduring brilliance. To help you in this task, we’ve compiled a comprehensive guide in our blog titled ‘How to clean a diamond engagement ring’‘. This guide is designed to aid you in preserving the pristine condition of your diamond, ensuring it continues to sparkle and captivate for years to come.

We’ve answered some of your most frequently asked questions about lab-grown diamonds below:

Do Lab Grown Diamonds Get Cloudy?

No, lab-grown diamonds do not get cloudy over time. The clarity of these diamonds is maintained as they are structurally identical to real diamonds. Cloudiness in diamonds is usually a result of inclusions or imperfections internal to the structure, and this characteristic are equally possible in both lab-grown and mined.

Do Lab Diamonds Last As Long As Mined Diamonds?

Yes, lab diamonds last as long as mined diamonds. Since they have the same hardness and durability, lab-grown diamonds withstand wear and tear like mined diamonds. The longevity of a diamond, whether lab-created or mined, depends on how well it is cared for rather than its origin.

Do Lab-Created Diamonds Lose Their Sparkle?

A lab-grown diamond will not lose its brilliance any more than mined diamonds will; the shine of a diamond is due to its cut and its refractive properties, which are identical in both types.

Will A Lab-Grown Diamond Lose It’s Colour?

A lab-created diamond will not lose its colour. Both the CVD diamond and HPHT diamonds are stable, and some lab-grown diamonds are treated with methane gas and UV light during the creation process to enhance colour, but once this process is complete, the colour is permanent.
