FAQ

Frequently Asked Questions

WHAT ARE THE DIFFERENCES BETWEEN MOISSANITE AND DIAMOND?

Physically and optically speaking, the two stones are very similar. While a diamond is composed of 100% crystallised carbon, moissanite is composed of crystallised silicon carbide, which gives it some singularities: Moissanite has higher refractive and dispersion indices, which is why it has a more colorful scintillation than diamond. On the other hand, diamond has a hardness of 10 on the mohs scale, while moissanite ranks 9.25mohs. This means that moissanite is the second hardest gemstone in the world, above sapphire and slightly below diamond.

IS MOISSANITE SIMILAR TO ZIRCONIA?

No. Moissanite is not similar to zirconia. In both hardness and brilliance, moissanite is superior. Moissanite is for life, it does not fade with time and use.

IS MOISSANITE FOR ME?

Moissanite is the best choice for anyone who wants a stone with the beauty and durability of a diamond, at a fraction of the cost, and who cares about the environment.
On average, the extraction of one carat of diamond requires the removal of more than 1,750 tonnes of earth, which has a tremendous environmental impact. Moreover, it is well known that unethical diamond mining practices have been a source of conflict in many regions.

WILL MY MOISSANITE LAST A LIFETIME?

Yes. Being the second hardest stone in the world, moissanite will last a lifetime. However, any gemstone (even a diamond) can suffer from cracks and chipping when exposed to a strong impact, especially if the stone was not optimally cut. PERPETUA selects excellently cut stones to ensure maximum durability.

DOES MOISSANITE LOSE ITS BRILLIANCE?

No. Moissanite will never lose its original brilliance. However, products residues such as soap, shampoo and lotion can stick to your moissanite blocking the light and making it look dull. This happens with all gemstones and can be solved in two minutes! Find our recommendations for cleaning your Perpetual jewellery below.

HOW MUCH DOES A MOISSANITE COST?

Just like a diamond, the price of moissanite will depend on the qualities of the stone you're buying in terms of weight (size), color, clarity and cut, mainly. What we can say is that our price can in some cases be up to ten times lower than that of a natural diamond.
All this will depend on your preferences.  At PERPETUA we will give you all the advice you need to buy the best stone at the lowest price. 

WHY IF MOISSANITE IS SO SIMILAR TO A DIAMOND, THE PRICE IS SO LOW?

Certainly, the cost of producing a diamond is higher because it has to be extracted from a mine or created in a laboratory at constant temperature and pressure. In addition, there is a whole chain of intermediaries that raise the cost of the product. However, the price of natural diamonds is exaggeratedly high due to the marketing and market control practices that large companies have implemented for more than 100 years. In reality, natural diamonds are not as scarce or as valuable as we have been led to believe. When you buy a natural diamond, you are paying very high profit margins for the companies, as well as centuries-old marketing.
At PERPETUA we work directly with the best moissanite and laboratory diamond producers, so we can offer extremely low prices by cutting out other intermediaries.

DO THE MOISSANITES HAVE ANY KIND OF CERTIFICATE?

Every PERPETUA moissanite comes with a certificate issued by the Gem Research Institute (GRI), which specifies the qualities of your stone in terms of colour, clarity, weight, dimensions, cut and symmetry.
Each stone has an individual report number that you can track yourself at any time from the GRI website. 
The report number will be included in the certificare that will come along you ring.

IS A LABORATORY DIAMOND A FAKE DIAMOND?

No. A lab diamond is just as real as one extracted from a mine. Because it has the same chemical composition, it also has the same qualities of beauty, brilliance and durability. Until a few years ago, the cost of producing laboratory diamonds exceeded the price of natural ones, making them uncompetitive in the marketplace. Recently, their production has become more efficient and have also increased in quality, so that today even the best known jewelry companies have expressed interest in laboratory diamonds.

IS A LAB DIAMOND CHEAPER THAN A MINED DIAMOND?

Yes, lab diamonds are usually marketed between 30% and 40% below natural diamonds. At PERPETUA we make an expert selection so that you can access the best diamond, for the best price.

HOW IS A LAB DIAMOND CREATED?

There are different methods for its creation. The two most common and the ones that give the best results are known as HPHT (High Pressure, High Temperature) and CVD (Chemical Vapor Deposition). Both methods subject diamond seeds and carbon particles to temperature and pressure conditions similar to those in the earth's core, where natural diamonds are crystallized.

ARE LAB DIAMONDS CERTIFIED?

Yes, at PERPETUA we are convinced of the value of having a diamond certified by an external laboratory. For this reason, all our diamonds are IGI (International Gemological Institute) certified, which specifies the qualities of the diamond.

CAN A DIAMOND BREAK?

Diamonds, whether natural or lab-created, are the hardest known mineral, and as such, it is very rare for them to break. What can happen is that imperfections in the stone, known as inclusions, can compromise the physical structure of the diamond. For this reason, PERPETUA only sells diamonds with very high clarity grades, ensuring that the structure of the stone is in no way compromised,  allowing your  diamond to last for centuries.

WHICH ONE IS BETTER: A LAB DIAMOND OR A MOISSANITE?

There is no right answer to this question. Eventually, it will all depend on your preferences, but here are a few thoughts:
Moissanite has excellent refractive and dispersion indices, making it a beautiful gemstone for jewelry. While it is slightly less hard than a diamond, it is still the second hardest gemstone in the world, which ensures its durability in a piece of jewelry.  In addition, moissanites are significantly more affordable than a lab diamonds, making it a very attractive option for those who want a large stone without at more discrete budget.

The diamond also has excellent indexes of refraction and dispersion, which is why it has long been the gemstone of choice for jewelry. While its price is high, it also carries a message of romance that some people do not wish to part away from. For those who want a diamond, PERPETUA Lab-Grown Diamonds will be the best choice, as they retain that romance, are environmentally friendly and fairly priced.

WHAT MAINTENANCE DOES MY PERPETUA PIECE NEED?

To remove product residues that accumulate with daily use, all you need is hot water, dish soap and a soft bristled toothbrush. Mix water and a few drops of the soap in a bowl, immerse your piece in the water and let it sit for a few seconds. Start cleaning it with the brush, paying special attention to the back of the stone that is closest to your finger. Rinse it in clean water and dry it with a cloth.
That's it! By doing this every couple of weeks, you will help your moissanite or diamond to stay as clean as possible.

Please note however, that all fine jewelry requieres maintenance every once in a while. We will be happy to properly care for your pieces!
