Frequently Asked Questions
In this FAQ section, I have tried to answer the common questions asked by the customers about Moissanite, Moissanite testers etc., So let’s check out the FAQs:
Do Diamond Testers Work on Moissanite?
A diamond tester will test as positive, even for moissanite. In other words, a diamond tester read both diamond and moissanite as diamond as result.
This is because a diamond tester runs a thermal conductivity test on a gem to authenticate whether the gem is a diamond or not, and moissanite happens to share this same property as diamond; so, they read them as diamond.
Can You Test Moissanite?
Use a moissanite tester if you want to test moissanite. It is one of the most convenient ways to test moissanite. The moissanite tester will run an electrical conductivity test on the gem to know if it is moissanite or not because moissanite is electrically conductive. The result is based upon how well the gem conduct electricity.
Are Moissanite Testers Accurate?
Using a moissanite tester to see the authenticity of a gem is one of the most convenient ways for testing. Moissanite testers are mostly accurate, as they compare the performance of electrical conductivity with a diamond. But there are exceptions.
There are two types of rare diamonds that can also conduct electricity almost as well as moissanite. They are the Type II diamond and the ‘Black Diamond’.
Can You Tell the Difference Between Moissanite and Diamond?
There are many ways to tell the difference between a diamond and moissanite. Even if moissanite is the most identical stone to a diamond, there are many features between them that differentiate. Such features as that are the way they sparkle, and their refractivity.
There are also many conventional ways to test a stone to see if it is a diamond or moissanite. Flashing a ray of light above its base to see how they reflect.
If it gives out rainbow-colored lights then it is probably moissanite, if it gives clean white light then it is a diamond. Moissanite sparkles twice as much as diamonds sometimes.
Does Moissanite Get Cloudy?
Moissanite do not change its color easily, even if it is being used over time. Moissanite cannot become cloudy suddenly. Only if oil and dirt build up on the surface of the stone over time, then it can affect the look of that stone.
This happens because oil and dirt block the light and prevent them to shine through the stone. This is something that can make them look cloudy.
Does Moissanite Lose Its Sparkle?
Moissanite does not lose its sparkle very easily. They are known to have their clarity and color intact for years. They take a very long time for their sparkle to degrade in any way. Having dirt and grime inhibiting on a moissanite ring for a long time may be the only reason for their sparkle to diminish until they are cleaned.
Does Moissanite Look Fake?
Moissanite is the only stone that is as close as a diamond to be its perfect replica. Yes, moissanite maybe half the price of a diamond in monetary value, but they are the perfect alternative for a diamond and definitely worth something.
Average people cannot distinguish between a diamond and moissanite with just naked eyes. You will need to have expertise and experience with stones to tell moissanite just by looking at them. They are lab-grown and cannot be found naturally occurring on earth that can be set on jewelry.
Many people use moissanite as a substitute for diamonds, and they are still undetectable to regular eyes. The major difference between a moissanite and diamonds is how they sparkle. It is safe to say that moissanite sparkle even more than diamond.
Can You Wear Moissanite in the Shower?
Water cannot directly harm your moissanite. It is not the water itself that can harm your moissanite, but the chemical components in the water may affect the gemstone in various ways.
They could be minor and temporary impacts, but highly dissolved minerals can leave hard spots from water that may dull the sparkle of the stone and may be fixed by cleaning.
Moissanite is very durable and resistant to scratch, so it is also important to know how many adverse effects can water have on it. There is always the chance that you may jump on the pool, while wearing moissanite jewelry or get soaked on the beach, took a shower wearing it, or maybe be caught in a rainstorm.
This means there is always the chance that your moissanite jewelry might come into contact with water, so it has minimum resistance to lasting against it occasionally.
Water may be solvent for materials in the very long term, but that does not mean it will damage your moissanite immediately. Your gemstone might get damaged because of hard water, but it is a very rare occurrence and likely to happen if it’s kept like that for a long time.
Can You Wear Moissanite Every Day?
Moissanite pieces of jewelry are pretty durable if you ask me, after all, they are the second hardest stone to diamond among all the gems out there.
Moissanite gemstones are 9.25 Moh on the scale of hardness, which means they are very much suitable for wearing every day and very unlikely to perish.
Will Moissanite Last Forever?
Moissanites are very strong and long-lasting gemstones. You might be able to carry moissanite for your entire life, and it is likely to last without damaging its appearance. Moissanite rings will last for a very long time on settings made from a high-quality metal such as platinum or gold.
Does Moissanite Have Resale Value?
Moissanite is much cheaper than a diamond. They do not have much resell value because they are less expensive. They are not likely to increase in value any sooner. Reselling moissanite is at a substantial loss if resold right after purchase.
Can Moissanite Cut Glass?
Moissanite is the second hardest stone known to man after diamond. They have 9.25 Moh rating on the scale of hardness. That being said, of course, they can cut glass.
Glass has a rating of 5.5 Moh on a scale of hardness, and diamond is 10 Moh rating on the scale of hardness. These ratings clearly show that you can scratch, or cut glass with moissanite and diamond easily.
What Is the Most Diamond-Like Moissanite?
Round cut moissanite resembles most with a diamond. The round cut moissanite looks close to a diamond because of the way it interacts with the light, the almost same way it does with a diamond. The proportion of the facets of round-cut moissanite matches that of a diamond.
Round moissanite has properties that match the standard proportions of a diamond. Such specificness is replicated in the round-cut moissanite. There is no ideal or fancy cut grade for diamonds, the cushion cut itself has 10 different variations in their cuts.
What Is the Best Cut for Moissanite?
Round cuts are considered to be the most popular cuts among the moissanite because they sparkle the most. The Round cuts have 58 facets carefully angled cut to reflect light through the top of the stone surface. These facets are angled in a fashion where it does not allow the light to escape from the bottom or sides. They bring fire and brilliance to your stone.
Which Brand of Moissanite Is Best?
Unlike diamonds, moissanites are lab-grown gems. They were synthesized in labs to look like diamonds and sparkle even more. They do not occur naturally on earth. Their origin was first found on a meteorite from space, crashed in Arizona. So different companies produce them. Here are some well-known brands for moissanite-
- Charles and Colvard
- Forever One
- Lux Moissanite
- NEO Moissanite
- Harro Gem Premium Moissanite
How Can You Tell Good Quality Moissanite?
A good quality moissanite is mostly considered by its cut. It kind of depends on how it reacts with the light, passing through the stone and returning. Moissanite is considered to be of good quality judging on its dispersion level, the way they give brilliance like an immense fire.
Can I Pass Off My Moissanite as a Diamond?
There are some moissanite rings that can be passed off as a diamond sometimes. The two stones are different, but moissanite does not look fake. This is what gives it an edge over inexperienced eyes. Most people won’t even be aware that it is moissanite, not a diamond until they run tests on it.
A professional will be able to tell the difference between a moissanite and diamond if he/she looks thoroughly or run some conventional tests on it, otherwise, it can be passed as a diamond very easily to naked eyes who have no idea about stones.
Do Forever One Moissanite Look Like Diamonds?
Forever One Moissanite is a very clear and sparkly gemstone, which looks almost like a diamond. They were discovered by Dr. Ferdinand Henri Moissan from a meteor crater. They are very durable and almost like diamonds visibly, but that does not make them fake for diamonds.
Is Moissanite Fire a Natural Gemstone?
Moissanite is a lab-grown synthesized gemstone, that is made artificially. They give off a fire-colored sparkle, but that is not the only color they give off. They have much more variation. A diamond is a pure carbon, where moissanite is carbon silicate.
Can Moissanite Be Found in Nature?
Moissanite was first found in a meteor crater that came from outside space. They do not occur naturally on earth. They are lab made and prepared to be set into jewelries that way. It first originated from the upper mantle rock of meteorites in Arizona, and their natural form is rare.
