Lab Grown Diamonds

Also known as lab-created or synthetic diamonds, lab grown diamonds are an often misunderstood gemstone. Let's delve into their creation process, understand what sets them apart, and explore why and how their efficient production leads to a significantly lower cost compared to natural diamonds.


What is a Lab Grown Diamond?

Laboratory grown diamonds are precious gemstones cultured in a laboratory, where they undergo an accelerated diamond creation process that mimics millions of years of natural formation. This innovative approach not only results in a more environmentally conscious option but also offers a more affordable alternative to traditionally mined diamonds.

Lab Grown Diamonds vs Natural Diamonds

You might be wondering if a lab grown diamond is a real diamond, and the answer is yes! Lab made diamonds share identical physical, chemical, and visual properties with natural diamonds. The sole distinction lies in their origin, as one is cultivated in a laboratory setting, while mined diamonds undergo a natural formation process in the Earth over millions of years. Find our more in our full guide on the differences between lab grown and natural diamonds.

Lab Grown Diamond Value

The value of lab-grown diamonds is determined by various factors including their quality, size, colour, clarity, and cut, similar to natural diamonds, take a look at our guide on the 4Cs to learn more about this grading system. Generally, lab-grown diamonds are priced at a lower cost compared to natural diamonds of similar characteristics, as they do not require mining and come with a reduced environmental impact. Our lab grown vs natural diamond price guide explores these differences in more detail.


Being a relatively recent addition to the market, the future price of lab diamonds is uncertain. Whether lab diamonds will see a reduction in cost in the future remains unclear. The potential for the value gap between lab-grown diamonds and natural diamonds to widen or narrow is still undetermined as the market continues to evolve.

How Lab Diamonds Are Made

Time to get scientific! Lab grown diamonds are made using two primary methods: High Pressure, High Temperature (HPHT) and Chemical Vapour Deposition (CVD). HPHT uses extreme pressure and temperature to replicate the conditions of the Earth's mantle, where natural diamonds are formed. CVD involves using a gas mixture to deposit carbon atoms onto a substrate, which gradually builds up a diamond crystal. Our full guide: 'how are lab grown diamonds made' answers everything you need to know about this fascinating process.

Lab Diamond Hardness

Lab-grown diamonds have the same exceptional hardness as natural diamonds, ranking as a 10 on the Mohs scale of mineral hardness! This unparalleled hardness makes lab-grown diamonds an ideal choice for everyday wear, as they are highly resistant to scratches and abrasions. 


Whether adorning an engagement ring, pendant, or pair of earrings, lab-grown diamonds offer durability and longevity that ensure they retain their brilliance and beauty for generations to come. Additionally, their hardness makes them suitable for various settings and styles.


The Mohs scale of mineral hardness is a scale used to measure the scratch resistance of various minerals. It assigns a relative hardness value to minerals based on their ability to scratch or be scratched by other minerals. With 10 being the hardest (diamond).

Lab Diamond Colours

White lab diamonds come in a spectrum of shades, offering a diverse array of choices for consumers seeking ethical and sustainable alternatives to traditional mined diamonds. These lab-grown diamonds can exhibit variations in tone and hue, ranging from a bright, icy white to a warmer, creamier undertone. The colour grading scale, commonly used for diamonds, categorises these shades on a scale from D (colourless) to Z (light yellow or brown). Lab diamonds in the D to F range are virtually indistinguishable from their mined counterparts, boasting a brilliant, pure white appearance.

Lab Diamond Sustainability

Choosing lab-grown diamonds over mined ones offers significant environmental benefits, with the creation process being less energy-intensive and avoiding extensive land disturbance. Unlike traditional diamond mining, which contributes to deforestation and water pollution, lab-grown diamonds have a smaller carbon footprint and reduce the strain on local water sources.
