Frequently Asked Questions

Questions commonly asked by our customers and answered by our company experts.

What is Moissanite?

If you haven't heard of Moissanite (aka gem quality silicon carbide), its appearance is often mistook for a diamond. However it is no diamond simulant. It surpasses a diamond in both fire and brilliance. Its superior hardness make it ideal for heirloom quality jewelry as it is extremely resistant to scratching, chipping and breaking. Our Moissanites are cut and polished better than the majority of diamonds commonly sold in engagement rings. In addition, for the socially conscious, Moissanite is ethically sourced and environmentally friendly.

Moissanite was first discovered in minute quantities from particles carried to earth by a meteorite 50,000 years ago. It is now available as faceted gemstones in a large array of shapes and sizes.

Unlike other diamond alternatives that can cloud and dull with time, Moissanite is just as atomically stable as a diamond and so its impossible for it change color or lose its optical properties with time. In fact, given that Moissanite is more heat resistant than diamond, it can be argued its even more atomically stable. Therefore you can rest assured your Moissanite jewelry will sparkle for a lifetime and beyond.

Is Moissanite Graded on the GIA Color Grading Scale?

GIA has developed a color grading scale which is commonly used in diamonds, and the same scale can be applied to Moissanite. According to the GIA scale

  • Grades D, E, F: colorless
  • Grades G, H, I: near coloress
  • Grades J, K: faint color

So what does that mean? Grades D, E, F and even G are completely colorless and can be described as "icy" white. Grade H and I still look white, but its a slightly warmer or steely white. When you get into the J and K range, you will start to see a bit of yellow.

So what is the difference between D and F color? In reality, little to nothing. One needs to have special lighting, expert training and view the diamond or Moissanite loose (not set in jewelry) and upside down to tell the difference. The difference between D and F is a difference on paper only. Even once set in jewelry and in normal lighting, its difficult to tell the difference between a D color and a G or even H color stone.

Will Moissainte become dull and fade with time?

Moissanite is an extremely hard, tough and durable substance that will not cloud or change physical and optical properties with time. It is the type of heirloom gemstone that can be passed down from generation to generation and look just as brilliant as the day it was first purchased.

Charles & Colvard provides a warranty on the optical properties of Moissanite gemstones. Since the properties of moissanite are inert, and can never change, the warranty is offered as confirmation that moissanite will retain its properties forever. It is expected that there will never be an instance where a warranty claim would be necessary. Like all such warranties, the C&C warranty does not cover abuse or damage to the gemstone. Click here to view the C&C warranty card. To protect your Moissanite gemstone and jewelry against damage we would recommend obtaining jewelry insurance.

How do I clean and care for my Moissanite?

Moissanites do need care to keep them at their brilliant best. A clean Moissanite will reflect light better and allow its fire and brilliance to show. That added brilliancy makes the Moissanite look larger than one that has been "dulled" by oil from the skin, soaps, cosmetics, and everyday activities.

One of the advantages of Moissanite over diamonds or any diamond alternative available is that it does not have the same affinity towards grease and oil. That being said it is still a good idea to clean your jewelry about once a month to keep them sparkling as brilliantly as possible.

Here are four simple ways to keep your Moissanite gemstones looking their best:

The Detergent Bath

Prepare a small bowl of warm soapy water. Use any mild liquid detergent that does not contain "soap" for it creates another type of "film" on the surface of the Moissanite. A mild liquid detergent would be something like original Dawn dish detergent. We do not recommend the use of any abrasive cleaners for any type of jewelry. Brush pieces gently with a toothbrush and rinse well. A hair dryer may be used to finish drying the jewelry.

The Cold Water

Another home cleaning process you can do is to make a cup of a solution containing water and household ammonia or similar product like Mr. Clean. We recommend about 3/4 parts of water and 1/4 part of the cleaning chemical. Let the Moissanite jewelry soak for about 10 minutes and with a toothbrush gently tap around the back and front of the mounting and if you can, try to reach behind the mounting where dirt would have accumulated. Rinse it well with warm to hot water and dry it with the help of your blow dryer. (We don't recommend the use of towels for drying your jewelry).

Commercial Home Jewelry Cleaners

You can purchase one of many formulated, non-toxic liquid jewelry cleaners such as GemCare. These cleaners are ideal for effectively removing the "film" that can accumulate on a gemstone surface.

Ultrasonic Cleaner

This is the most effective option for maintaining the brilliance of your Moissanites. It is the method our jewelers use prior to shipping customers' orders. It creates a high-frequency turbulence which can clean most of your jewelry.

Additional Recommendations

You may try to avoid using your fine jewelry while playing sports (working out in a gym is included here) or when you do any kind of rough work. Even though a Moissanite is the most durable natural crystal structure known to man, it can be chipped by a hard blow along its grain.

When you are not wearing your Moissanite jewelry, try to separate them individually. Moissanite pieces in a drawer or left in contact with other jewelry in a jewelry case can scratch each other and also can scratch other jewelry.

Is Moissanite resistant to heat & chemicals?

Durability is a material's ability to remain intact or withstand exposure to temperature and chemicals. Moissanite can easily withstand temperature variations during the jewelry manufacturing process and repairs at a jeweler's bench (unlike other gemstones such as cubic zirconia or emerald). In fact, Moissanite has a higher vaporization temperature than diamond and can withstand temperatures reaching 2,000 degrees Fahrenheit.

Moissanite is also very stable when exposed to various chemicals, solutions and acids typically used during both manufacturing and jewelry repair that commonly damage other less stable gemstones.

Will Moissanite Scratch Easily?

Hardness refers to a gemstone's resistance to being scratched or abraded and is commonly expressed as a number ranking (1 being the softest and 10 being the hardest) on Mohs relative hardness scale.

Moissanite ranks 9.25-9.50 on the Mohs scale making Moissanite one of the hardest gemstones on earth. It's unusually high hardness makes scratching and abrasions very rare, even after many years of daily wear and tear.

Moissanite's ability to resist abrasion and scratching easily outranks and is more than double (120%) the hardness of any popular diamond simulant such as Diamond Nexus (CZ), Russian Brilliants (CZ), or Sona Diamond (CZ).

Is Moissanite resistant to chipping?

Yes. The ability of a gemstone to remain intact, withstand force (pressure) and resist breaking or chipping is known as toughness. Determined by a substance's atomic and chemical structure, toughness can vary directly within a gemstone.

While both Moissanite and diamond are rated excellent in toughness, Moissanite has a different atomic structure than diamond which does not have a direction of cleavage (which sometimes is considered as a direction of structural weakness) like diamond. Simply said, Moissanite outranks diamond in overall toughness.

What is the Difference Between F1 and MC?

The new Moissanite is made of the same type of Moissanite crystal as the Forever One brand (called 4H Silicon Carbide). We are lovers of the Forever One Moissanite and continue to proudly offer it. Our new brand is simply a lower cost alternative for those customers who demand high quality, but don't necessarily need a name brand.

The MoissaniteCo brand is colorless (D-G color), visually flawless clarity (VVS+), and the cut and polish is excellent. The Forever One is offered in both colorless (D-F) & near colorless (G-H), VS average clarity and the cut and polish is excellent

We are offering the same warranty as Charles & Colvard does on the Forever One Moissanite, including warrantying larger stones (5mm and larger) against damage, although there may be a partial replacement fee in the case of damage.
