Moissanite is one of the most durable gemstones used in jewelry, second only to diamonds. It is very hard (Mohs 9.25), highly scratch resistant and handles rough exposure exceptionally well.
However, like all gemstones, proper maintenance is required to keep the stone sparkling at its best. Luckily, maintaining a moissanite gemstone is fairly easy and with these few common sense tips, you’ll be able to keep your moissanite sparkling through the ages.
Cleaning Moissanite at Home
Keep things simple. One of the best ways to clean moissanite jewelry is to simply use a mild soap like this one, warm water and either a soft cloth or toothbrush. Place the moissanite jewelry in the soapy solution, then gently brush the stone, taking care to get into the hard to reach areas. Once cleaned, rinse thoroughly to get rid of any soapy residue.
Dry the moissanite jewelry well on a lint-free cloth.
Commercial Jewelry Cleaners
If you decide that you need something more professional than soap and water, you can opt for a commercial jewelry cleaner specially formulated for use on gemstones such as diamonds, moissanite and corundum.
Choose a non-toxic, non-abrasive cleaner like this highly recommended one and follow the instructions to have your moissanite sparkling clean.
Using Ammonia on Moissanite
Ammonia may sound like a strong chemical, but it is actually a safe, natural product that is very effective in cleaning moissanite jewelry. If you think you will be sensitive to ammonia, wear goggles and gloves and work in an airy space.
To make the solution, dilute 1 part ammonia with 1-2 parts water. Place your moissanite jewelry in the solution, then use a soft brush to clean the pieces thoroughly. Once complete, you can wash with soap and water, or simply rinse under running water.
Moissanite and Ultrasonic Cleaners
Moissanite is tough enough to be used in ultrasonic cleaners and this is often a good way to restore the stone’s sparkle if faded. The intense vibrations can effectively get rid of the grime on your stone. Most jewelers use ultrasonic cleaners to professionally clean jewelry.
However, if the stone is mounted in a more fragile setting such as a pave setting, it is best to avoid using the ultrasonic cleaner as it can cause little stones to fall out.
What to Avoid
Avoid harsh chemicals when cleaning your moissanite. This includes household detergents, cosmetics, hair sprays and chlorine. While these may not directly damage the moissanite, they add to the grime build up and reduce the sparkle of the stone.
Storing Moissanite with Other Jewelry
Moissanite is very hard, which means that it is likely to scratch other softer gemstones and metals. It is best to store moissanite jewelry in a separate pouch or fabric-lined jewelry box.
True, moissanite can withstand rough exposure, but this doesn’t mean that it cannot be damaged. Hard impact along its grain can cause moissanite to chip. It’s best to take of your moissanite ring (pendants and earrings are fine) to avoid damage when engaging in physical activities like sports, hiking, gardening and so on.
Does Moissanite Get Cloudy?
This is a common question often asked by our readers. The good news is that moissanite never gets cloudy, unlike inexpensive diamond simulants such as cubic zirconia.
However, over time, as dirt and grime accumulate, your moissanite can appear filmy. Because moissanite never gets cloudy internally, any filmy appearance is purely surface and can be removed by cleaning.
What is the Moissanite Oil Slick?
Oily rainbow stains on a moissanite stone.
This refers to the oily appearance on the surface of the stone that can appear like rainbow stains due to organic film build-up. This is not a permanent stain and can be removed by cleaning.
The best way to clean this oil slick as recommended by the top moissanite retailers, is to use silver polish and a toothbrush. Use a silver polishing cream like this one with a brush on the surface of your moissanite and then rinse off. The oil slick will come off and the stone will sparkle beautifully. You can do this as desired if you want an extra clean for your moissanite.
If you purchased your moissanite from Charles and Colvard, you can contact them regarding any oil stains. They often send out a special polishing cloth to use on your moissanite that also does the trick perfectly.
How Often Should I Clean Moissanite?
There are no rules as to when you should clean moissanite. As a general rule of thumb, once a month should be enough or whenever you notice the stone, or its setting, looking dirty.
