How to identify real moissanite stones?

Many people wonder how to identify real moissanite. The gemstone is often visually mistaken for a diamond because both sparkle very intensely and are frequently cut in the same brilliant cut. At the same time, moissanite is sometimes compared to cubic zirconia, even though they are completely different materials. In this article, we explain how to identify moissanite and what the differences are compared to diamonds and cubic zirconia.

How can you identify real moissanite?

Identifying real moissanite with the naked eye is not always easy. Even experienced jewelers can sometimes barely distinguish it from a diamond because both stones look very similar and sparkle intensely. Often, special testing devices or a precise examination are used to clearly identify moissanite.

Is the double refraction of moissanite recognizable?

Yes. Under a magnifying glass, a diamond appears clearer and calmer, while moissanite displays a lively, playful play of colors with iridescent light reflections.

Can you distinguish moissanite from diamonds?

Yes. Moissanite often sparkles slightly more intensely and shows more color reflections than a diamond. Furthermore, the stone possesses what is known as double refraction, which causes light to disperse differently within the gemstone.

Is moissanite just cubic zirconia or something similar?

No. Moissanite is an independent gemstone made of silicon carbide and differs significantly from cubic zirconia. The stone is harder, more durable, and displays a different type of sparkle. While cubic zirconia is often used only as an inexpensive fashion stone, moissanite possesses properties that bring it much closer to diamonds.

Does moissanite pass a diamond tester?

Yes, in many cases, moissanite can pass a simple diamond tester. The reason is that moissanite conducts heat almost as well as a diamond, which is what many testing devices measure. This is why laboratories use specialized equipment and more precise tests to clearly distinguish between diamonds and moissanite.

Why moissanite is so hard to distinguish from diamonds

Identifying real moissanite is often more difficult than many people think. Visually, the gemstone can look very similar to a diamond, especially when it is cut in a brilliant cut and sparkles intensely. Many simple diamond testers with a thin tip and a red-green display only measure the thermal conductivity of a gemstone. This is precisely the reason why moissanite often passes a diamond tester. The stone conducts heat almost as well as a diamond, which is why such devices often cannot clearly distinguish between moissanite and diamonds.

To truly identify the difference between moissanite and diamond with certainty, specialized laboratory equipment is usually used to analyze other properties of the gemstone. Some moissanite stones also have a very small engraving on the stone that confirms their origin. However, this is usually only visible with a strong magnifying glass or under a microscope and is therefore hardly noticeable in everyday life. This is exactly why moissanite looks very similar to a diamond in many pieces of jewelry – for example, in sparkling moissanite rings or classic moissanite earrings, where the intense sparkle of the gemstone is shown to its best advantage.

Can you identify moissanite at home?

Identifying moissanite at home is possible but not always definitive. With the naked eye, the gemstone is difficult to distinguish from a diamond, as both sparkle very intensely and are often cut in the same brilliant cut. One possible indication can be the sparkle: moissanite often produces slightly stronger color reflections in the light, whereas diamonds often appear somewhat more neutral. Especially in direct light, the stone can therefore appear very lively.

Another clue can be a strong magnifying glass. Moissanite possesses what is called double refraction, which can make reflections in the stone appear slightly doubled under strong magnification. A diamond does not possess this property. Double refraction is one of the reasons for the special play of colors of moissanite and plays a major role in its intense sparkle.

How to distinguish moissanite from cubic zirconia

Identifying the difference between moissanite and cubic zirconia is usually somewhat easier than the comparison with diamonds, but it still requires a trained eye. Cubic zirconia often appears somewhat glassier and can look as if the stone has more facets than it actually does. The sparkle often looks more uniform and less lively. Moissanite, on the other hand, usually shows clearer facets and produces many small light reflections that can appear particularly lively.

Another difference lies in the hardness of the stones. Moissanite is among the harder gemstones and is significantly more resistant than cubic zirconia. Theoretically, one could try to scratch the stone slightly: if the stone is damaged in the process, it is very likely cubic zirconia. If, however, the surface remains undamaged, it could be moissanite. Such tests should be carried out only with caution, as jewelry can be damaged in the process.

Difference between moissanite, cubic zirconia, and diamond

Moissanite, cubic zirconia, and diamonds often look similar at first glance, but they differ significantly in their properties. The following table shows the most important differences between the three gemstones.

Moissanite falls between diamond and cubic zirconia in many of its properties. The gemstone is significantly harder and more durable than cubic zirconia and displays a very intense sparkle. In our moissanite hardness test, we even show how resistant the stone really is and why its high hardness can be a great advantage in everyday life. At the same time, moissanite can look visually very similar to a diamond, which is why the two gemstones are frequently mistaken for one another in everyday life.

Which gemstone is the best choice?

All three stones have their own properties and can look very beautiful in jewelry. For centuries, diamonds have stood for rarity and luxury, while cubic zirconia is often used as an inexpensive stone in fashion jewelry. Moissanite has also become increasingly established in recent years because the gemstone combines many properties that are particularly valued in everyday life. It possesses an intense sparkle, high hardness, and very good resistance to scratches and wear.

Many people therefore consciously choose moissanite because the stone remains brilliantly clear over the long term while being significantly more affordable than a diamond. While cubic zirconia often loses its luster over time, moissanite retains its brilliance for many years. This makes the gemstone particularly suitable for jewelry that is worn regularly, such as moissanite rings or moissanite earrings, where the sparkle is intended to be permanently maintained in everyday life.

With us, this philosophy is taken even further. Our moissanite jewelry is consciously crafted from 925 sterling silver and finished with 18k white gold plating. This combination gives the jewelry an elegant, high-quality appearance while keeping it affordable. Sterling silver is robust enough for everyday use, and the white gold plating additionally provides a bright, high-quality surface that matches the sparkle of moissanite very well. The result is jewelry that can be worn permanently without quickly losing its radiance – and at a price that won't break the bank.
