The following article talks about the difference between CVD or synthetic diamonds and naturally mined diamonds. It creates a realistic impression of the two kinds of diamonds.

1. Man Made Diamonds vs Natural Diamonds
As we all know - Nothing shines as brightly as diamonds. This is not something people
will choose to argue with. Yet, for a long time now, these rarely found stones have been
extremely expensive for anyone but the rich ones to own. The reason for the diamonds
to be rare is the process by which these gemstones are naturally created; its creation is
known to take hundreds of millions of years in specific conditions inside the earth’s
crust. These diamonds are made by natural forces so deep inside the earth, that the
amount of pressure and heat that they’re subjected to make it impossible for anything
else to survive. Humans can only get these natural gems when they’re naturally brought
to the earth's surface by volcanic eruptions.
However, thanks to the multiple advancements in science, it is now possible for humans
to create lab manufactured diamonds are every bit as good and beautiful as the natural
ones. In fact, these man made diamonds are so well made that only sophisticated
chemical testing can differentiate between the created gems from the earth-mined gems.
In fact, the only way that gives away the difference is the tiny imperfections in the
natural diamonds. The man made diamonds are absolutely perfect. Another key
difference is that the natural diamonds are more expensive than the lab-grown or
synthetic diamonds for obvious reasons. The creation of lab made diamonds takes a few
weeks while that of the natural diamonds through geological forces takes millions of
years. Honestly, there’s nothing else that will distinguish them as in fact they are both
diamonds that are equally beautiful and have the ability to leave you spellbound.
Synthetic diamonds are manufactured through 2 major methods – the first method is
called HPHT – high pressure, high temperature method. This method is about
reproducing the natural conditions that provoke diamond production. This is a widely
used method, thanks to its relatively low cost. It involves placing into a belt type of a
press graphite dissolved into molten iron, cobalt, or nickel that act as a catalyst, helping
the dissolution of carbon and its eventual conversion into a diamond. This method is
ideal for diamond making and not for jewellery making.
Another method used by the lab grown diamonds growers to create diamonds under
controlled conditions in a laboratory is Chemical Vapor Deposition (CVD) – primarily
ideal for gem-quality diamonds, owing to its ability to control the chemical purity and
the ultimate qualities of the produced gemstone to a great extent. With the CVD method,
a thin wafer of diamond is placed into a special container. In the next step, various gases
are fed into the container and ionized to produce a plasma, which later rains down onto
the substrate. It then led to a diamond growing from the ground up.
Man made diamonds have gained enough popularity in the last few years, thanks to
their explicit shine and beauty that replicate the natural diamonds. The simplest
difference between these two types of diamonds is that the CVD diamonds are created
through the technological advancements and the natural ones are created through the
earth’s art. However, the prior are more affordable and undeniably more approachable.
