Does Moissanite pass Diamond Tester?

A diamond tester is a device used to distinguish between real diamonds and imitations. Diamond testers are an essential tool for jewelers and gemologists to differentiate between genuine diamonds and other stones. Moissanite is a naturally occurring mineral that is often used in place of diamonds due to its high brilliance and durability.

While visually like diamonds, moissanite has different physical properties that may cause it to react differently when tested by a diamond tester. In this article, we will explore whether Moissanite pass Diamond Tester and what factors affect its test results.

Regular Diamond Tester

A regular diamond tester becomes essential in determining the authenticity of your gemstones. Without proper testing equipment, one can easily mistake a moissanite for a diamond. A regular diamond tester will help distinguish these two gemstones by checking their thermal conductivity levels – diamonds conduct heat better than moissanites. Investing in high-quality jewelry is crucial; hence it’s essential to know what you’re buying.

How to different between and a Moissanite and Diamond?

When it comes to buying an engagement ring, one of the most common questions people ask themselves is whether to go for a moissanite or a diamond.

One way to differentiate between moissanites and diamonds is by observing their sparkle. Diamonds have a unique brilliance that can’t be replicated by any other gemstone. When light enters a diamond, it refracts and reflects inside the stone multiple times before being dispersed back out, creating what is known as “fire.”

Moissanites also have this effect but tend to produce more colorful flashes of light compared to diamonds’ white sparkles. Another factor that sets these two stones apart is their hardness level.

In-Depth Explanation to Understand the difference between a Moissanite and Diamond

Moissanite and diamond are two of the most popular gemstones used in engagement rings and other jewelry. While both have a brilliant sparkle, there are some key differences between the two that should be understood before making a purchase. Moissanites are made up of silicon carbide. Diamonds, on the other hand, are formed from pure carbon under extreme heat and pressure deep within the Earth’s mantle.

One of the main differences between moissanites and diamonds is their physical properties. Moissanites have a higher refractive index than diamonds, which means they reflect lighter and have more fire or rainbow-colored flashes when viewed from different angles. This can also make moissanites appear slightly less bright or white compared to diamonds because they disperse light differently.

What is Diamond?

Diamond is one of the world’s most coveted and valuable gemstones. It is a mineral made up of pure carbon that has been compressed over millions of years under extreme pressure and heat deep within the earth’s mantle.

The physical properties of diamond tester are what make it so unique and desirable, it is the hardest known naturally occurring substance on earth, with a Mohs scale rating of 10. This means that diamond can scratch virtually any other material out there, including other gems like sapphires and rubies.

What is Moissanite?

Moissanite is a rare, naturally occurring mineral that was first discovered in 1893 by French chemist Henri Moissan. It is composed of silicon carbide, which makes it one of the hardest minerals on Earth.  Natural moissanite is incredibly rare and too small to be used for jewelry purposes.

Instead, most moissanite jewelry today is made using lab-created stones. Lab-created moissanite has become increasingly popular over the years as an alternative to diamonds.

Moissanite Vs. Diamond

Moissanite and diamond are two of the most popular gemstones for engagement rings. Although they both appear similar at first glance, there are a few key differences that set them apart. Moissanite is a man-made stone that is almost as hard as a diamond, but it has different optical properties which give it more fire and brilliance than a diamond. 

The main difference between moissanite and diamonds is their price point. Moissanites are significantly less expensive than diamonds, making them an affordable option for those who want a similar look but don’t want to spend as much money.

Some people still prefer diamonds due to their status symbol or because they believe they hold more value over time compared to moissanites. We also read and tell...

What makes Moissanite so special?

Moissanite is a rare and naturally occurring mineral. It has become increasingly popular as an alternative to traditional diamonds due to its affordability, durability, and ethical sourcing.One of the most unique characteristics of moissanite is its fire or dispersion. This refers to the way it refracts light into a rainbow of colors.

This property makes moissanites especially popular for engagement rings and other pieces of jewelry that are meant to catch the eye.

Cost-effectiveness of Moissanite

When it comes to cost-effectiveness, moissanite truly shines. A one-carat diamond can easily fetch thousands of dollars, while a similar-sized moissanite stone may only cost a fraction of that amount.

Not only does this make moissanite an attractive option for those on a budget or looking to save money on their engagement ring or jewelry purchase but it also means you can get more bang for your buck when upgrading your jewelry collection.


Moissanite may not pass a diamond tester due to its differing thermal conductivity, it is still a beautiful and high-quality alternative to diamond. Its durability, brilliance, and affordability make it an attractive option for those looking for a more ethical or budget-friendly choice.

Ultimately, the decision between moissanite and diamond should come down to personal preference and values. It is important to educate oneself on the differences between the two to make an informed decision.


·        Can a jeweler distinguish between Moissanite and Diamond tester?

There is no definite way to differentiate these jewels from one another. They are difficult to differentiate to the naked eye, and even under a jeweler’s loupe.

·        What is the downside of Moissanite?

They’re Way Too Shiny. Moissanite has a crazy amount of sparkle. Its refractive index is higher than a natural diamond’s, producing more shine and a special kind of fiery rainbow brilliance.

  • Can Moissanite is GIA certified?

Natural moissanite is comparable to a GIA-certified K-color diamond

·        Is Moissanite a fake Diamond?

The truth is that moissanite is not a synthetic diamond tester or the often-dreaded cubic zirconia, it’s a totally separate gemstone that is naturally occurring, though extremely rare and found in meteorites.
