Why Choose Lab Grown Diamonds?

Lab grown diamonds offer several advantages over their mined counterparts, making them the preferred choice for conscious consumers:

Ethical and Environmentally Friendly

Lab created diamonds are created in controlled environments, eliminating the negative impacts of mining on ecosystems and communities.


These diamonds provide the same dazzling appearance at a fraction of the price, making them a more cost-effective option.

Lab grown diamonds are identical to their natural counterparts, offering not only identical brilliance but also a more cost-effective alternative.


Lab grown diamonds exhibit the same physical, chemical, and optical properties as mined diamonds, ensuring a high-quality, beautiful product.

The Science Behind Lab Grown Diamonds

Lab created diamonds are created using two main methods:

High Pressure High Temperature (HPHT)
This process mimics the natural formation of diamonds by subjecting carbon to high pressure and high temperature conditions. The result is a diamond crystal that is virtually identical to a mined diamond.

Chemical Vapour Deposition (CVD)
In this method, a diamond seed is placed in a chamber filled with a carbon-rich gas mixture. The gas is heated, causing the carbon atoms to separate and deposit on the diamond seed, creating a crystal layer by layer.

Lab Grown Diamond Grading

Lab grown diamonds are graded using the same criteria as mined diamonds, known as the 4Cs:

    • Carat: Refers to the weight of the diamond, with one carat equating 200 milligrams.
    • Colour: Diamonds are graded on a scale from D (colourless) to Z (light yellow or brown). Lab grown diamonds can be found in a range of colours, including rare hues like blue and pink.
    • Clarity: Indicates the presence of inclusions and blemishes within the diamond. The clarity scale ranges from Flawless (FL) to Included (I).
    • Cut: Determines the diamond’s brilliance, fire, and scintillation. A well-cut diamond will reflect light internally and disperse it through the top, creating a stunning sparkle.

Each lab grown diamond receives a certificate from a reputable gemological laboratory, such as the Gemological Institute of America (GIA) or the International Gemological Institute (IGI), to guarantee its quality and grading.

Comparing Lab Created Diamonds and Mined Diamonds

While lab grown diamonds share the same properties as mined diamonds, there are some key differences:

    • Formation: Mined diamonds form naturally over billions of years deep within the Earth, while lab-grown diamonds are created in a matter of weeks in controlled laboratory conditions.
    • Traceability: Lab grown diamonds can be traced back to their point of creation, ensuring ethical sourcing and transparency.
    • Inclusions: Lab grown diamonds may have unique inclusions, such as metallic flux or gas bubbles, which can help distinguish them from mined diamonds.
