Lab grown diamonds are an eco-friendly, ethical alternative to mined diamonds. They have the same physical characteristics as natural stones and can be cut into any shape or size you desire. HPHT (high-pressure, high-temperature) and CVD (chemical vapor deposition) processes mimic nature’s method of creating a diamond in a controlled environment with extreme heat & pressure conditions that replicate what happens deep below the earth’s surface over millions of years. Our lab grown gems offer superior brilliance at a fraction of the cost compared to traditionally sourced ones, without compromising on quality.

High Pressure High Temperature (HPHT) lab grown diamond process:

The HPHT process involves a containment cube containing carbon, usually an existing diamond. Then, it is subjected to intense pressure and heat through electric pulses, which causes the crystallisation of the carbon into a rough lab created diamond in around one month’s time. The resulting stone is cut with laser precision or traditional polishing techniques to its desired shape before being certified by graders such as GIA, who assess criteria like colour, clarity and carat weight, amongst other details confirming that it was produced using this method.

1.       Carbon (usually a small, existing diamond) is contained in a containment cube

2.     The cube is pressed to enforce the same pressure a diamond faces under the earth’s surface

3.     The cube is intensely heated through electric pulses

4.     The heat and pressure causes the carbon to crystallise

5.     A rough lab diamond is produced in a matter of weeks, typically around one month

6.     The rough diamond is cut with laser precision and traditional polishing techniques into the desired shape

7.     The HPHT diamond will undergo certification. Graders like GIA assess the cut, colour, clarity and carat weight, amongst other details, and certify that the diamond is lab created by HPHT

Chemical Vapour Deposition (CVD) lab grown diamond process:

Chemical Vapour Deposition (CVD) is a process that begins with the selection of a thin slice of diamond, 300 microns thick and around 10x10mm. The selected piece must be thoroughly cleaned before being injected into an airtight chamber filled with carbon-rich gas heated to extreme temperatures. Nitrogen can be added, but this will yellow the stone, so good synthetic producers often avoid it. The gas breaks down over time, coating the diamond and building up its carat weight, creating a rough square cube which is then cut and polished using laser precision or traditional polishing techniques before certification from graders like GIA assesses its colour, clarity etc., certifying it as CVD created.

1.       A thin slice of diamond is selected, 300 microns thick and around 10x10mm. This diamond slice is typically taken from an already lab created diamond

2.     The diamond slice is thoroughly cleaned, as any defects will grow with the diamond, forming inclusions

3.     The diamond slice is injected into a chamber

4.     The chamber is securely sealed to keep any traces of other gas out

5.     The chamber is flooded with carbon rich gas and heated to extreme temperatures

6.     At this stage, nitrogen can be added to the gas to speed up the process - but good synthetic diamond producers avoid this, as it yellows the diamond

7.     The gas reacts by breaking down, coating the diamond slice and bonding to it

8.     The chamber continues to be filled with gas over a couple of weeks, continually breaking down and coating the diamond slice, building up the carat weight

9.     A rough lab diamond is produced, which looks like a square cube

10.   The rough diamond is cut with laser precision and traditional polishing techniques into the desired shape

11.     The CVD diamond will undergo certification. Graders like GIA assess the cut, colour, clarity and carat weight, amongst other details, and certify that the diamond is lab created by CVD
