What is Moissanite?

Moissanite has made a name for itself around the world as an ethical gemstone at the pinnacle of brilliance. It has revolutionized the jewelry industry by surpassing diamonds in gloss and heat resistance, and is available at a much more affordable price point. Beyond daily use, it is also immensely popular as bridal or travel jewelry.

Why choose Moissanite?

Ethical

Free from the problems that plague the jewelry industry as it does not require mining, moissanite it the ethical and sustainable option.

Value

Not only is the price per carat less expensive than many other gemstones, but fancy color options are also available.

Durable

Excellent durability with a Mohs hardness of 9.25 to 9.5. Resistant to oil and grease and with a shine which does not become cloudy, moissanite is easy to clean.

What is moissanite?

Moissanite was discovered in 1893 by Henri Moissan, a French scientist who later won the Nobel Prize in Chemistry. He discovered the stone in a crater created by the Canyon Diablo meteorite in Arizona, USA. At the time of the discovery, Dr. Moissan thought he had found a diamond because of the stone's spectacular brilliance and clarity, but in 1904 he found that the crystals were made of silicon carbide, which made the stone different from a diamond. Thus, moissanite was named after its discoverer, Dr. Moissan. In fact, natural moissanite was so rare that it had never been used in jewelry at the time, but since the 1980s, researchers have been experimenting with it, and in 1998, lab-created moissanite was introduced to the jewelry market. Today, it is one of the world's most brilliant gemstones, and together with its ethical appeal, it is favored by many people around the world.

Sustainable

One carat of moissanite consumes 1/100th of the energy required to produce a lab-grown diamond. Additionally, natural diamonds require mining and are said to consume about twice as much energy as lab-grown diamonds. MIYAMA moissanite uses 100% recycled metals and offers a new ethical alternative that is sustainable and environmentally friendly.

Moissanite Detailed Benefits

Ethical

 

Moissanite is an ethical gemstone, free from the problems that have plagued the jewelry industry (conflict funding, poor working conditions, environmental destruction, etc.). Moissanite is also more environmentally friendly, as it is carefully manufactured in a laboratory and emits much less carbon dioxide than diamonds.
Affordable Price

 

Compared to diamonds of the same size, moissanite is significantly less expensive. You can get the center stone of your dreams without sacrificing size, clarity, cut, or color. This allows more people to enjoy jewelry and makes it easier to enjoy larger stones.
Excellent Durability

 

Moissanite is extremely rugged and durable and is also resistant to scratches, abrasion, chipping, and breakage. In terms of toughness, it is superior to diamond with a Mohs hardness rating of 9.2 out of 10. This indicates that its surface is not easily scratched, chipped, broken, or cracked.
Beautiful Brilliance

 

Moissanite is truly the world's most luminous gemstone. It boasts a fire value 2.5 times that of diamonds, making it more radiant than diamonds. Its refractive index is as high as 2.69, making it more brilliant than the 2.41 of a typical diamond. Furthermore, moissanite boasts a surface luster index of 20.40%, higher than that of diamonds at 17.20%. This means that moissanite has a higher luster than diamonds.
Excellent Quality

 

We are able to provide a stable supply of beautiful stones of high quality because moissanite is made in our lab. Therefore, large stones can be offered at reasonable prices.
At present, there is no international evaluation standard for moissanite, but all moissanite used by MIYAMA is only moissanite with an Excellent cut within the colorless (DEF) range of the 4C standard for diamonds.
Excellent Heat Resistance

 

Silicon carbide, the constituent material of moissanite, is extremely chemically stable and has excellent heat resistance. While diamond has a heat resistance of approximately 800°C, moissanite has a heat resistance of up to approximately 1800°C.
Easy Care

 

Diamonds are lipophilic, so their brilliance is often clouded by cosmetic issues and various daily oil stains, requiring that they often be cleaned and maintained. Moissanite, however, is resistant to oil and grease, so its brilliance lasts longer. 
Variety of Shapes and Colors

 

A wide variety of shapes are available: round, emerald, heart, oval, pear, square, and cushion. In addition to colorless diamonds, we also have a lineup of fancy colored (pink, yellow, etc.) moissanite. They are also popular as a new alternative to the very expensive natural fancy color diamonds.

FAQ's

Moissanite does not lose its sparkle and continues to shine as the months go by. The clarity and color of the stone will not change over time, but as with any gemstone, stains on the stone's surface can inhibit its brilliance. However, moissanite is resistant to oil, making it less prone to fogging and easier to clean.

Moissanite is a rare natural mineral composed of silicon carbide (SiC), discovered by Nobel Prize-winning chemist Dr. Henri Moissan in a crater created by a meteorite impact in Arizona. Moissanite, due to its structure, has excellent durability and is 2.5 times more brilliant than diamonds. It is also significantly less expensive than diamonds and in recent years has been widely used for fashion jewelry as well as engagement rings.

Moissanite is one of the most durable gemstones available. Diamonds have a cleavage property that can cause them to crack or chip upon impact during normal use, but moissanite has no cleavage property and boasts superior toughness compared to diamonds. Moissanite also has a high Mohs hardness rating of up to 9.6, which indicates the surface's susceptibility to scratching, making it ideal for engagement rings and other jewelry worn daily.

Moissanite passes as a diamond when using a diamond tester that detects thermal conductivity. This is because, unlike other gemstones such as cubic zirconia, it has a high thermal conductivity. Such moissanite (silicon carbide) is similar to diamond in appearance and characteristics, but it is composed of a different substance than diamond (carbon). Moissanite, which is extremely durable, brilliant, lustrous, and heat resistant, has gained popularity among people due to its attractiveness as a gemstone.

Moissanite and diamonds are so similar in appearance that it is difficult to visually distinguish them, but they can be identified using a device called a moissanite tester, which is used to distinguish between the two. Another method is to use a loupe to look at the top of the gemstone from an angle. In moissanite, you will see two slightly blurred lines, indicating double refraction.
