Moissanite engagement ring

Wedding means rings.

Today, we have an abundance of brilliant choices.

We are inundated with different colors, designs and gems.

Moissanite is one of these jewels.

  • Is moissanite a good diamond alternative?
  • How hard is moissanite?

These are probably just two of the questions you have in mind.

And we have the answers.

But let’s handle the first question about its origin:

Is moissanite man made?

The answer is yes and no!

Moissanite is a gemstone rarely found in nature.

Thankfully, scientists have found ways to produce them in the lab.

Nearly all moissanite jewelry you’ll come across, are man made.

Now, let’s have a closer look to this shiny jewel.

1. What is Moissanite?

Moissanite is a naturally-occurring silicon carbide that was discovered in 1893.

It is not a diamond or morganite.

They sound close but are different.

The name of this gemstone comes from its discoverer Henri Moissan.

This French chemist was inspecting rocks in a meteor crater in Arizona.

He took stone samples, which he thought were diamonds at the time.

After 10 years, he realized that they had a different structure.

They were made of silicon carbide, not carbon.

Today, almost all moissanite jewelry carry man produced stones.

It is cost efficient because it is produced in controlled environments.

It is widely used in electronics and optics for its superior properties.

Moreover, it has minimal impact to environment.

This makes it an affordable eco-friendly jewel!


The color ranges from colorless to slight yellow or brown tint.

From these, the clear and colorless ones conduct higher prices.

Moissanite stones do not get cloudy because they have a very stable structure.

They are very resistant to heat.

Does moissanite scratch glass?

Moissanite is very hard.

It has a high rating on the Mohs scale

Glass gets 5.5 on the Mohs scale while Moissanite is near the top with 9.25.

Thus it can scratch glass.

Only harder materials can scratch these stones.

Diamond has the top place with 10.

This indicates a very high level of hardness.

It is very rare that a moissanite jewelry will encounter physical contact with a harder material.

2. Moissanite vs Diamond Side by Side Comparison

Moissanite Diamond
Hardness 9.25 10
Density 3.21 to 3.22 3.5 to 3.53
Dispersion 0.104 0.044
Refractive Index 2.69 2.42


What is moissanite fire?

Crystals refract different wave lengths by different angles.

When light enters a crystal, it gets dispersed into different rays of light for each angle.

This dispersion forms a rainbow like view as in the video above.

This is called moissanite fire.

These jewels outperforms even diamond in this aspect.

It has a much greater dispersion index than diamond.

Thus, when it is subject to a ray of light, the colors will be more separated and more visible.


Brilliance is the ability of the stone to reflect white light or “sparkle.”

While diamonds are brilliant, these simulants may be more so.

Colorwise there is an important difference: Moissanite is not graded by color in the same manner as diamonds.

However, as with diamonds, the smaller the gemstone, the less color it will contain or be visible.

Standard moissanite has a similar color to K-color diamonds.

You may also find nearly colorless jewels.

Moissanites are easier to maintain than diamonds.

They do not have rough edges that attract dirt and grease.

Diamonds are the hardest known mineral on earth, scoring at the top of the scale with a “10”.

Moissanite is close behind with a 9.25 rating that makes it quite hard and durable.

Still, for many people the hardness factor is nearly indistinguishable.

This is the biggest difference between these two stones, based on the classic cut and clarity along with other considerations.

Moissanite costs a fraction compared to diamond.

In the end, if you want diamond engagement ring, that is a matter of personal taste and selection.

While moissanite is not a diamond, it is quite close and makes a great gem.

3. How to Take Care of Moissanite Jewelry

As we have seen above, Moissanite stones are one of the hardest gems with 9.25 on the Mohs Scale.

This means very few materials may scratch them.

One of them is diamond which has a greater hardness rating.

Thus you should not keep your diamond and moissanite jewelry in the same pouch or jewelry box.

Store your jewelry in individual small bags, which will keep from separated from another jewelries.

This way, you can be sure that, when next time comes, they will be ready.


It is very rare that you may encounter with a material hard enough to scratch your moissanite jewelry.

But that does not mean you should wear them during work like gardening or outdoor activities.

Don’t forget that the metal parts are not as hard and durable as the gemstones.

The metal parts are softer, thus they may get scratched more easily.

Wearing your moissanite engagement ring only in low risk activities is always a good idea.

Cleaning moissanite jewelry

Dirt and oil may get to your jewelry and diminish its beauty.

In this case, a mild soapy water and a soft cloth should be to enough to clean them up.

Never leave your jewelry wet. Always finish the cleaning by drying them completely.


As usual, make sure other gemstones and the metal are safe for your cleaning process.

Never proceed with any cleaning activity before being totally sure that every single part will not be harmed.
