Real photos show what a Moissanite ring can really withstand. Almost as hard as a diamond and with more sparkle. In real scratch and sawing tests, we show how durable Moissanite really is.
Moissanite is known to be one of the hardest gemstones. On the Mohs scale of hardness, it ranks just below diamond with a hardness of approximately 9.25, making it one of the most durable materials used in Moissanite jewelry. Many people choose a Moissanite ring precisely because it is particularly robust for everyday wear and can be worn for many years.
But what can a Moissanite ring really withstand? How does the stone react to heavy loads, heat, or extreme tests that go far beyond what happens in normal everyday life?
It is known that Moissanite can, in rare cases, chip under very high stress. The crucial question, however, is under what conditions such a thing actually happens and how durable the stone really is in practice. That's why we wanted to know how much a Moissanite ring can actually withstand and tried some unusual hardness tests.
Moissanite vs. Angle Grinder – What happens when a mini angle grinder meets a Moissanite ring?
To see how durable Moissanite rings really are, we started with a simple but extreme test. For this, we used a small Dremel with a mini angle grinder and directly worked on a 3 mm Moissanite Eternity Ring made of silver. In this test, we deliberately did not hit the metal of the ring, but the top of the set stones. So, we ground precisely where the Moissanite stones are located in the ring.
The result was surprisingly clear. While the small silver prongs holding the stones in the ring were lightly ground, the Moissanite stones themselves remained completely unharmed. Even after we repeatedly went directly over the surface of the stones, they showed no visible damage. Although the settings were slightly abraded, they continued to hold the stones firmly in the ring.
This test clearly demonstrates how hard Moissanite actually is. While the silver of the ring shows traces relatively quickly, the stones themselves remain stable. Precisely this combination of a sparkling gemstone and high durability is one of the reasons why Moissanite is so frequently used today for rings that are worn daily.
Moissanite vs. Fire – What happens under extreme heat?
In the next test, we wanted to know how a Moissanite ring reacts to intense heat. For this, we used the same 3 mm Moissanite Eternity Ring again and heated it with a gas torch while the ring slowly rotated. The goal was to observe what happens to the stones and the silver when the ring is exposed to an open flame for an extended period.
After a short time, a visible change became apparent. The Moissanite stones began to glow yellowish under the heat, while the silver of the ring heated up more and more. Due to the high temperature, the metal softened and began to melt slightly. However, the flame was not strong enough to completely melt the silver, as it takes a relatively long time for the entire metal to reach the necessary temperature evenly.
Despite the extreme heat, the Moissanite stones remained firmly set in the ring. While the silver reacted much more strongly to the temperature, the stones themselves showed no structural damage. Such temperatures, of course, never occur in normal everyday life, but they clearly show how heat-resistant Moissanite fundamentally is.
Under what circumstances can a Moissanite stone really break?
After such tests, the question naturally arises whether a Moissanite stone can break at all. Even though Moissanite is one of the hardest gemstones, it is – like any material – not completely indestructible.
It is important to understand, however, that a break does not simply happen. Our tests have already shown that even direct mechanical stress or strong heat does not automatically lead to a Moissanite stone being damaged. In practice, this usually requires a very targeted and strong force applied to a sensitive point of the stone.
Typically, this only happens when a ring hits a hard, sharp edge with great force or when a localized force acts precisely on a corner of the stone. Such situations are rare in everyday life and differ significantly from normal stresses such as impacts, friction, or heat.
Precisely for this reason, Moissanite stones are considered particularly robust. The combination of high hardness and stable structure ensures that they often remain surprisingly durable even under unusual stresses. While a break is theoretically possible, in practice it requires significantly more force than many people initially assume.
In the video test, you can clearly see how the Moissanite glows yellow under the heat, while the metal of the ring slowly heats up. Even when we worked with the angle grinder, in the end, it was mainly the sterling silver that was damaged, while the Moissanite stones themselves remained astonishingly stable. These properties are precisely why Moissanite is considered a very durable gemstone in everyday life.
