Types of Synthetic Diamonds
Do you know that diamonds are among the most expensive gem stones in this
world? They are formed when elements inside the rocks are
subject through immense pressure and heat through the years. Diamonds are composed of natural carbon buried deep down earth for billion of years and are heated for approximately 2,200 degrees Fahrenheit or
1204.444 degrees Celsius. They also undergo a pressure of 725,000 pounds per
square inch and then quickly come into surface to cool. Once exposed to cool
temperature, they gain the crystal form before they are mined.
On the other hand, with the help of modern technology, the industry has found ways to manufacture synthetic stones that look like diamonds. Although they are not natural diamonds, their properties are similar and it takes a skilled diamond grader to
spot the difference. They are called artificial, simulated, lab grown or cultivated
The following article discusses the types of
synthetic diamonds manufactured in laboratories. This will also discuss the
difference between lab grown diamonds versus Czs. Do you think you can spot the
These are among the most common lab manufactured
diamonds. They look like natural diamonds, but they differ in chemical
compounds. These types of lab grown diamonds have been in the market since the
early 1970's. They are available in several forms including cubic zirconia,
moissanite diamonds, and Nexus simulants. There are also zircon and white
Kinds of simulant diamonds:
***Diamond Nexus Simulants. These are composed of a mixture of carbon and other
elements to create the diamond-effect. They are also durable and shiny but
require proper maintenance to retain its beauty. Nexus diamonds are also the
most durable simulant diamonds that is why they can be a little expensive than
other lab grown diamonds.
***Cubic Zirconia Simulants. These are manufactured from zirconium dioxide, a
laboratory-made element used to create other lab grown gem stones. They can
come in different colors. Cubic zirconia or zirconia diamonds are more common
are less durable. This is why they come in low prices. They are commonly used
as ornaments to jewelry and like earing and rings.Moissanite simulant diamonds. These are formed by combining
silicone carbide. They are the closest reflection to diamonds that is why they
are the priciest lab grown diamonds next to diamond Nexus.
How synthetic diamonds are produced?
Over the years, diamond laboratories have been
built to create replicas of natural diamonds. These laboratories have
state-of-the-art machines and expert chemist to mix elements and create
synthetic diamonds. One of the best known processes to create a synthetic
diamond is through HPHT or high pressure, high temperature process. When a
chemical, usually pure carbon, is subject to a very high pressure and high
temperature, chemical vapor is created, resulting to crystallization, creating
3D effect the similar effect to that of a natural diamond.
Comparing Synthetic Diamonds to Natural Diamonds:
As it was mentioned before, it takes a skilled
diamond grader to tell the difference between a natural diamond and a synthetic
or cubic zirconia diamond. If you only use your naked eyes, you can see that
they are visually the same.
Among their similarities include:
* White and colorless natural
diamonds and synthetic are both colorless
* They can be both cut
into different shapes
* They can be
transformed into different colors
Once we are settled with their similarities, let’s go
down to their differences. A natural diamond differs from a synthetic one in
the following points:
* Synthetic diamonds do
not have inclusions, whereas the inclusions in natural diamonds are like their
birth marks unique in each diamond.
* Natural diamonds come
in very higher price compared to synthetic ones.
* Natural diamonds
create illusions when you look at them closely. They say that each diamond has
its own identity, and that no diamonds are the same. Each diamond has its own edges
inclusions that create illusions.
* When they are placed
under an electronic device that can read a stone’s electrical and thermal
conductivity, you will be able to find the natural ones from the synthetic
ones. However, there are synthetic ones that have passed this test. This
synthetic cubic zirconia are manufactured very precisely that they resemble a diamond.
*Diamonds are more
durable than zirconia. You can place a diamond in fire and it will gleam like
before while zirconia might get tarnished or destroyed, especially when placed
in a very extreme heat and pressure.
Classic way of determining the natural diamond from
a cubic zirconia:
This is one of the widely known and classic but
recognized ways to tell if you have the natural diamond at hand. First, get the gem stone and place it on top
of a newspaper. Since the natural diamonds have the ability to refract light,
like a lot of it, it is very hard to read letters though it. You cannot see
through a natural diamond. A common cubic zirconia will be penetrated by light
and you will be able to read the letters through it.
Another classic way to determine a natural one from
a cubic zirconia is by breathing through it. Natural diamonds don’t hold heat,
which is why they clear out cloud instantly. While cubic zirconia absorbs heat
longer and stays cloudy for a period of time.
Where cubic zirconia CZs are sold:
Cubic zirconia is sold in many jewelry stores all
over the world. They are also offered in many online stores today. CZs come in
very intricate and elegant designs. When buying a set of earing or engagement
ring, make sure to inquire if they are natural diamonds or cubic zirconia. They
are as flawless and elegant as natural diamonds. When new, cubic zirconia
gleams like natural diamonds but they are prone to scratches and can be easily
damaged, especially when not maintained regularly.
Cleaning cubic zirconia diamonds:
Cubic zirconias are prone to scratches as they are
less durable than natural diamonds. You can polish it using a piece of cloth
when you only deal with dampness of shallow scratches. But if it is severely
damaged, it is advisable to bring it to jewelry cleaner for professional
cleaning. They often offer polishing to make it look like new again.
