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 diamonds.

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 difference?

Simulated diamonds:

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 sapphires.

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.
