Frequently Asked Questions about Lab Grown Diamonds  

Yes, lab grown diamonds are real diamonds. They are optically, physically and chemically identical to earth grown diamonds. The only difference between lab grown diamonds and earth grown diamonds is how they are formed: Lab grown diamonds are produced in a laboratory setting.

Once fully formed, both lab and earth grown diamonds are then cut and polished for maximum brilliance.

All our lab grown diamonds are IGI Certified.
Yes, they do. Lab grown diamonds are real diamonds: the only difference between lab grown and earth grown diamonds is their origin.
There are two ways lab diamonds are grown:

1. High Pressure High Temperature – HPHT
2. Chemical Vapour Deposition - CVD


This Earth-inspired method was brought to life in the mid-1950s and is known as “high pressure high temperature” (HPHT). A small diamond seed is combined with a carbon source, like graphite, and then placed in a giant mechanical press. There, in the presence of a catalyst, it’s subjected to temperatures of around 1,600 degrees Celsius and pressures of 5-6 Gigapascals in order to form a diamond. The force used is like balancing a commercial jet or the Eiffel tower on the tip of your finger. And in effect, this process recreates the conditions under which mined diamonds are formed in the Earth’s core.


The newer method is called Chemical Vapour Deposition, or CVD and is more akin to how diamonds might form in interstellar gas clouds. CVD diamond production is different from HPHT growth in two major ways. First, the diamonds are grown in a vacuum instead of under tremendous pressure. Secondly, CVD growth requires large, flat plates of diamond instead of small diamond seeds. To grow a CVD diamond, square diamond plates are placed into a vacuum chamber. The chamber, known as a reactor, is then injected with a hydrocarbon gas, such as methane, and the gas is heated, typically to 3,000 - 4,000 degrees Celsius. At the same time, high-power microwave energy is infused throughout the chamber, creating a hydrocarbon plasma that acts as a catalyst to break down the atomic bonds in the hydrocarbon mix. This separates the carbon atoms from the hydrogen atoms, and the resulting free carbon 'rains' down on the diamond plates, vertically growing the diamond atom by atom, similar to the way that snow collects on a table.
Yes, lab grown diamonds sparkle with the same brilliance and fire as earth grown diamonds. In fact, even the most experienced gemologist won’t be able to tell the difference between a lab grown and earth grown diamond without the help of very sophisticated technical tools.
No, lab grown diamonds do not fade or change color over time. They are chemically, physically, and optically identical to mined diamonds and so will not show any signs of fading or discoloration.
Lab grown diamonds are typically cheaper than mined diamonds because they are created in a lab, which is more efficient than the traditional mining process. Also, lab grown diamonds do not face the same scarcity issues as mined diamonds, which can affect their price.
The choice between a lab grown diamond and a mined diamond ultimately depends on personal preference. Lab grown diamonds are usually less expensive than mined diamonds due to the lower cost of production, but they are chemically, physically, and optically identical. Some people prefer the environmental benefits associated with lab grown diamonds while others prefer the traditional and historical value of mined diamonds.
