Why Lab Diamonds are Not Fake Diamonds

Are lab diamonds real diamonds?

There is no such thing as a fake diamond. There are just diamond simulants and diamonds.

Diamond Simulants

Diamond simulants are cheap facsimiles of diamonds such as cubic zirconias, moissanite, white topaz, and yttrium aluminum garnet (YAG). Diamond simulants do not have the same chemical composition, physical properties, or optical behavior of a diamond. Every known diamond simulant is weaker and softer than a diamond.

Ada Diamonds refuses to sell diamond simulants, as diamond simulants are not diamonds.


Diamonds are a crystal of carbon and can either be naturally formed by high pressure and temperature underneath the surface of the Earth, or they can be created above the Earth in what can only be described as a paragon of human achievement.

The illustrious Gemological Institute of America (GIA) concurs :

"Synthetic diamonds are diamonds.
They’re not fakes. They have all the same
physical & chemical properties
of a mined diamond." 

-Stephen ­Morisseau, Director, GIA

Merriam-Webster defines a diamond as:

A: native crystalline carbon that is the hardest known mineral, that is usually nearly colorless, that when transparent and free from flaws is highly valued as a precious stone.
B : crystallized carbon produced artificially

Ada Diamonds agrees with both Merriam-Webster and GIA that our laboratory-grown diamonds are not fakes. While our spectacular diamonds that we proudly sell are not natural diamonds, they are certainly not fake diamonds.

You may disagree with Ada Diamonds and concur with the Diamond Industrial Complex (DIC) that a diamond must come from beneath the Earth and be billions of years old, but from an objective scientific standpoint, that view is incorrect.

Chemical Definition of a Diamond:
A Cubic Crystal Allotrope of Carbon

Diamonds are merely one form of carbon: a cubic crystal structure of carbon. Other known forms of carbon are graphite, carbon black (coal), carbon nanotubes, graphene, and carbon nanofoam, which is one of the lightest known solid materials. These forms of carbon are known as allotropes.

It turns out that you can burn a diamond into CO2 or you can quickly transform a diamond into graphite in a matter of minutes if heated to 2000°C in an inert environment.

In fact, you could burn any diamond into CO2, capture the resulting CO2, separate the carbon from the oxygen, and then re-grow a new diamond from the carbon from original diamond.

In other words a diamond is not forever.

There's No Such Thing as Synthetic Carbon

The DIC aggressively lobbying the FTC to call laboratory-grown diamonds by the term 'synthetic' diamonds. Furthermore, the DIC is fighting tooth and nail to prevent the term 'cultured' diamonds.

Why? They believe that the term 'synthetic' cheapens the product and promotes the 'fakeness' of lab-created diamonds. Furthermore, it creates confusion between lab-grown diamonds (which are diamonds) and diamond simulants (which are not diamonds).

Unfortunately for the DIC, the term 'synthetic' is chemically inaccurate for diamond, as a diamond is not a synthesis of multiple ingredients. A diamond is carbon, and there is no such thing as synthetic carbon.

Thus there is no such thing as a synthetic diamond.

Other Allotropic Transformations

Carbon is not the only allotropic element; Iron, Silicon, Phosphorus, and Oxygen are all elements that have multiple allotropes.

Two allotropes of Oxygen are Dioxygen (O2) and Ozone (O3). O2 makes up 21% of the Earths atmosphere, and the ozone (O#) layer of the stratosphere protects the Earth from the sun's harmful rays. On a regular basis, UV energy from the sun breaks apart the oxygen bonds and oxygen we breathe becomes ozone and ozone is broken down to become O2 again. The transition between O2 and O3 also happens in human created processes.

For example, most hot tubs sold today have an 'ozonator' that generates ozone from atmospheric oxygen to sanitize the water and reduce the need for harsh chemicals.

The reason we discuss oxygen transformation is that by the arguments made by the DIC, ozone generated by a hot tub would be 'fake' or 'synthetic' ozone. Which again, is chemically inaccurate. There is no such thing as synthetic oxygen.
