Lab Grown Diamonds (The Ultimate Guide)
Adhering to the title itself, a Lab-grown Diamond is 'grown' in the lab by employing a cutting-edge and innovative technology that replicates diamond growth's natural process. The product is a human-made diamond that is physically, chemically, and visually the same as those found beneath the Earth's surface.
What are lab-created (lab-grown) diamonds?
It is essential to
acknowledge the intricacies of that process, but a simple analogy would be
test-tube babies. Akin to that process, lab-created diamonds are
formed by providing conditions like those found under the Earth. By ensuring
the same heat and pressure, an environment is created to make these diamonds.
These diamonds are
ecologically friendly as they do not comprise the Earth's well-being. Coupled
with that, these diamonds are free of the deplorable and depraved history of
blood diamonds. And it doesn't end there as these diamonds are more uniform yet
cheaper than their earth-mined counterparts.
How are lab-grown diamonds created?
To adequately
perceive lab-created diamond formation, it is essential to know how mined
diamonds are formed. Both processes share a host of similarities but are
separated by their environment – one happens naturally while the other takes
place in a lab.
A much-concurred
belief was shared by a plethora of Mines
Diamond Geologists that diamond formation took place within the Earth
between 1 billion to 3 billion years ago. While it is still up for debate how
those diamonds came to form, the consensus is that the process begins with
carbon dioxide, which is deeply buried approximately 100 miles underneath the
Earth's surface.
The carbon is
subjected to heat rising upwards of 2,200 degrees Fahrenheit and exposed to the
extreme pressure of approximately 727,000 pounds per square inch. From thereon,
these diamonds are then moved to Earth's surface from the core by a series of
deep volcanic explosions. These movements are rife with pressure.
There are essentially two laboratory methods to grow man-made diamonds - High Pressure High Temperature (HPHT) and Chemical Vapour Deposition (CVD).
High Pressure High
Temperature (HPHT) Method:
HPHT diamonds method includes using one of three manufacturing
processes: the cubic press, the split sphere (BARS) press, and a belt press.
These processes occur in an environment that facilitates a tremendously high
temperature and pressure, ideal for diamond growth.
An HPHT diamond
starts as a minute diamond seed that is nestled in carbon. By employing one of
the manufacturing processes listed above, the seed is subjected to a searing
temperature of around 1500 degrees Celsius and subjected to pressure with
nearly 1,500,000 PSI.
During this process, the pure carbon begins to melt and forms a
diamond around the seed. The diamond is meticulously cooled to become a pure
carbon diamond.
Chemical Vapour Deposition (CVD)
Method:
In the case of a CVD
diamond, the process begins with the thin slice of a diamond seed, which is
often produced through HPHT. The diamond seed is inserted into a sealed chamber
and subsequently heated to around 800° C.
The chamber is subsequently filled with gas rich in carbon, like
Methane and other such gases. From thereon, the gases go through ionization to
become plasma by employing technology similar to that of microwaves or lasers.
The ionization process severs the molecular bonds teeming in the gases, and
from thereon, the pure carbon adheres to the diamond seed. The process
culminates in the slow crystallization of the seed.
How long does it take to grow a diamond in a
lab?
The diamonds made in the laboratory are either produced through
High pressure High temperature techniques (HPHT)
or Chemical Vapour Deposition (CVD) techniques. In both procedures, it
takes 6-10 weeks to form in a laboratory.
Can lab-grown diamonds be labelled the
same as natural diamonds?
The answer is
no; the
labelled diamonds are not like natural
diamonds. Though they are even the most intricate, and laboratories certify
these as diamonds, the significant difference is the origin of these gems and
their rarity. Lab-grown diamonds are
not mined from Earth and are instead grown in a controlled lab environment,
while natural diamonds are mined and rare.

Why Lab-Grown Diamonds?
Lab-created
diamonds
are both ethical and environmentally friendly, alongside which they aren't
drenched in the misery associated with blood diamonds. Among all other reasons,
the most important is its price. Lab-grown
diamonds are 70-80% economical than natural diamonds.
Are the lab-created diamonds graded
and certified?
Yes, they are graded and certified by employing the same process
as diamonds which are mined. Diamonds are sent to a laboratory that is
specifically built for this process. Most of these labs grade using the 4c's (color, clarity, cut, and carat).
The process is devised to provide each diamond with a disinterested grade. Now,
multiple b2b platforms share the trustworthy certificate and review of the
diamond. This makes the purchase more legit and valued.
Are lab-grown diamonds GIA certified?
Yes, since 2007, GIA has been grading laboratory-created/man-madediamonds. Since July 1, 2019, GIA Laboratory-Created Diamond Reports and identification reports have stopped using the term 'synthetic'. The process includes the standard clarity, color, and cut grading metric for reference reasons. In October 2020, GIA introduced LGDR— redesigned digital-only laboratory-grown diamond reports that contain 4'Cs specifications. These reports have a QR code that will redirect to a link with educational information about the laboratory-grown diamonds, including how GIA differentiates them from natural diamonds.
