Diamonds have long symbolised timeless elegance, commitment, and luxury. But in recent years, lab-grown diamonds have emerged as a popular and sustainable alternative to traditionally mined stones. For those curious about what lab-grown diamonds are and how they compare to natural diamonds, this guide will break down the facts, myths, and key considerations.
At Vuoi, we believe that understanding your jewellery, its origins, craftsmanship, and meaning empowers you to make informed, confident choices. Let’s explore the fascinating world of lab-grown diamonds and why they may be the perfect choice for your next piece of fine jewellery.

What Exactly Are Lab-Grown Diamonds?
They are, quite simply, real diamonds. They are created using advanced technology that replicates the natural conditions under which diamonds form in the Earth’s mantle. The result is a diamond that is chemically, physically, and optically identical to a mined diamond.
These diamonds are often referred to as 'cultured' or 'engineered' diamonds because they are grown in highly controlled laboratory environments rather than extracted from the earth. It’s important to note that lab-grown diamonds are not the same as diamond simulants like cubic zirconia or moissanite, those stones merely mimic a diamond’s appearance but do not have the same composition, brilliance, or hardness.
Lab-grown diamonds offer the same sparkle, clarity, and durability as their natural counterparts, making them a genuine choice for engagement rings, earrings, and special gifts.
How Are Lab-Grown Diamonds Made?
High Pressure High Temperature (HPHT)
HPHT replicates the natural conditions in the Earth’s mantle, where diamonds form under immense pressure and heat. A small diamond seed is placed into a carbon source, then subjected to extreme temperatures (over 1,400°C) and pressure (approximately 5 GPa) until the carbon crystallises into diamond around the seed.
Chemical Vapour Deposition (CVD)
CVD involves placing a diamond seed in a vacuum chamber filled with carbon-rich gases. Under high temperatures, these gases break down, and carbon atoms deposit layer by layer onto the seed, slowly growing a diamond crystal.
Both methods produce authentic diamonds that are virtually indistinguishable from mined diamonds, even trained gemologists require specialised equipment to tell them apart.
How Do They Compare to Natural Diamonds?
When comparing lab-growns to diamonds, the key similarities and differences are:
Appearance and Brilliance: To the naked eye, lab-grown and natural diamonds are identical. They have the same sparkle, fire, and brilliance.
Durability: Both rate 10 on the Mohs hardness scale, making them equally suitable for everyday wear.
Certification: Lab-grown diamonds can be graded and certified by respected institutions such as the GIA (Gemological Institute of America) and IGI (International Gemological Institute), just like mined diamonds.
Price: They are typically more affordable, offering buyers a larger or higher-quality stone for their budget.
