Natural vs. Synthetic Diamonds: What Is the Difference?

Synthetic diamonds are a great alternative to natural ones, but many people tend to be suspicious of diamonds that are created artificially. Let’s see what synthetic diamonds really are and how they compare to naturally occurring diamonds.

How Natural Diamonds Are Created

Diamond is a substance that is made of carbon and has a crystal structure. In nature, diamonds are formed deep inside the earth, under high pressure and temperature.

In contrast to natural diamonds, their synthetic counterparts are created in laboratory conditions.

What is remarkable is that these beautiful stones you see in all kinds of jewelry are actually billions of years old.

How Synthetic Diamonds Are Made

In contrast to natural diamonds, their synthetic counterparts are created in laboratory conditions.

High temperature and pressure are used to mimic the conditions present during the formation of diamonds in nature.

Synthetic diamonds are also known as lab-grown, man-made, cultivated, created, or cultured diamonds.


Are Synthetic Diamonds Fake?

A lot of people incorrectly assume that synthetic diamonds are not real diamonds. However, this is not true. Although synthetics are not formed naturally, they have the same chemical composition and physical properties as natural diamonds.

So, synthetic diamonds are not fake, and their artificial origin has nothing to do with the fact that they are real diamonds in terms of structure.

Synthetic Diamonds Are Different from Simulated Diamonds

Many people seem to confuse synthetic diamonds with simulated diamonds (or diamond simulants).

Simulated stones, however, are not made of the same materials as the real thing – they only look similar, but their chemical structure and physical properties are different.

An example of a stone used as a diamond simulant is cubic zirconia.

Differences Between Natural and Synthetic Diamonds

So, if natural and synthetic diamonds have the same makeup, are there any differences?

Synthetic diamonds do differ from natural stones, but not as far as their fundamental structure is concerned. The main difference that can be observed is in the clarity of the stones.

Whereas most natural diamonds have internal flaws that occurred during the stones’ formation, synthetics tend to be cleaner.

This is because they are created through a controlled process designed to minimize defects, and as a result, there are fewer flaws in the crystal structure of synthetics.


Identifying Synthetic Diamonds

It is very hard even for an experienced jeweler to tell a synthetic diamond from a natural one. Usually, one needs special equipment to establish with certainty whether a stone is lab-grown.

It is highly unlikely for someone to be able to tell that a synthetic diamond is artificial just by looking at it with the naked eye, or even with a loupe.

The best way for a consumer to find out whether a stone is natural or created is to ask for its certificate (you shouldn’t buy diamonds that are not accompanied by such a document).

Diamond certificates issued by the G.I.A. (Gemological Institute of America), for example, indicate if the stone is synthetic.

Advantages of Synthetic Diamonds

One of the biggest advantages to buying a synthetic diamond is that compared with a similar natural stone, the created one is cheaper.

When you also consider the fact that synthetic stones usually don’t have large and visible inclusions, you realize that you can get a flawless or nearly flawless diamond at a lower price than what you would pay for a naturally clean stone.
