Wedding means rings.

And in today’s jewelry world, we have a wide selection of gemstone rings to choose from: different designs, different stones, different prices.

Diamonds may be forever but they definitely have serious alternatives.

You have heard about the diamond substitute called moissanite, but perhaps might not very familiar with it.

  • Is moissanite a good diamond alternative?
  • Is moissanite cheaper than diamond?

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

And we have the answers.

Let’s have a deeper look into the world of this shiny stone.

What is Moissanite?

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

What is the meaning of Moissanite?

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

This French chemist was inspecting rocks in a crater formed by a meteor in Arizona. He took samples of stones which he thought were diamonds at the time.

Only after 10 years, he realized that they had a different structure, and that were made of silicon carbide.

Despite nature did give us moissanite, it is rarely found.

But thanks to chemists, we are able to produce moissanite in labs.

Today, almost all moissanite rings, wedding bands and other jewelry do carry man produced stones.

As its production is conducted in controlled environments, it is cost efficient and has a minimal impact to nature. This makes moissanite a more affordable and more eco-friendly gemstone!

Moissanite is more than a diamond substitute

It’s beautiful look and similar properties make it a very good diamond substitute, similar to cubic zirconia.

Moreover, silicon carbide is used in many industrial applications because of how it can conduct heat, its hardness and durability, and the optical properties. It is widely used in electronics and optics for its superior properties.

What are different colors of Moissanite?

Moissanite do range from colorless to slight yellow or brown tint. From this color spectrum, the clear and colorless ones conduct higher prices.

Does moissanite get cloudy?

Moissanite does not get cloudy because it has a very stable structure. It is very resistant to heat and other physical effects.

Does moissanite scratch glass?

Glass gets 5.5 on the Mohs scale while Moissanite is near the top with 9.25. Thus moissanite can scratch glass but glass cannot scratch moissanite.

Only harder materials can scratch moissanite, which has a very high rating on the Mohs scale.

Diamond has the top place with 10 and Moissanite has a rating of 9.25 . This indicates a very high level of hardness.

It is very rare that a moissanite ring or wedding band will encounter physical contact with a harder substance.

Thus moissanite stones are extremely scratch resistant.

This makes moissanite a very good gemstone for engagement rings.

Moissanite vs Diamond

A great deal has been made about the similarities between moissanite and diamonds, but what are the differences? Is there a significant enough difference in terms of jewelry that you should prefer one over the other?

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


Brilliance: This refers to the ability of the stone to reflect white light or “sparkle.” While diamonds are quite brilliant, moissanite may be more so. Furthermore, they are easier to maintain because it does not have the rough edges that attract dirt and grease.

Color: 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 color similarity to K-color diamonds, but there are nearly colorless versions that are available.

In the end, both diamonds and moissanite have similar color variations depending on the stone that you order.


Hardness: 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.

Cost: This is the biggest difference between moissanite and diamonds based on the classic cut and clarity along with other considerations. Moissanite costs a fraction compared to diamonds, which makes it a real bargain for those who do not have the budget to afford diamonds.

In the end, if you want diamond jewelry, that is a matter of personal taste and selection. While moissanite is not a diamond, it is quite close and makes a great stone for some excellent jewelry.

How to Take Care of Moissanite Jewelry

As we have seen above, Moissanite stones are one of the top ranked gems on the Mohs hardness scale with a hardness value of 9.25.

This means very few materials may scracth moissanite. To name a few, diamond and

Thus it is very rare that you may encounter with a material hard enough to scracth your moissanite jewelry.

While your moissanite jewelry’s stones are very hard that does not mean you should wear them during work like house cleaning, gardening or high adrenalin outdoor activities.

Don’t forget that the metal parts are not as hard and durable as the gemstones. As the metal parts are softer, they may get scratched much more easily.

Thus keeping your jewelry away from physical contact and wearing them in low risk activities is always a good idea.

What might happen is 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 clean them up and restore their brightness.
