Does Moissanite Scratch?
How moissanite hardness affects daily wear, scratches and long-term durability.
How hard is moissanite?
Moissanite is highly resistant to scratching, which is one reason it works well in engagement rings and jewelry worn often. It measures about 9.25 on the Mohs hardness scale. Diamond is harder at 10.
The Mohs scale compares how well one mineral resists being scratched by another. A high number helps moissanite keep its polished surface during regular wear.
Can diamond scratch moissanite?
Yes. Diamond is harder than moissanite. Other moissanite stones can also cause concern when loose pieces rub directly against each other, so separate storage is a good habit.
Can moissanite chip even if it is hard?
Yes. Scratch resistance and resistance to impact are different properties. A strong hit against an exposed edge can damage many gemstones.
Pointed shapes such as pear, princess and marquise cuts benefit from settings that protect vulnerable areas.
Is moissanite durable enough for an engagement ring?
For most people, yes. Its hardness makes it suitable for a ring worn regularly. Setting design and maintenance still matter.

Can the ring scratch even if the stone does not?
Yes. Gold, silver and plated finishes can show scratches and wear more easily than moissanite. A scratched band does not mean the gemstone itself has been scratched.
How can you protect moissanite jewelry?
Remove rings for activities where they may receive hard impacts. Store pieces separately and have frequently worn settings checked if a prong becomes loose.

Frequently asked questions
Does moissanite scratch easily?
No. It has very high scratch resistance compared with many gemstones used in jewelry.
Can moissanite scratch glass?
A hard gemstone may scratch softer materials, but scratching objects is not a useful way to identify a gemstone.
Will moissanite look scratched after years?
A quality stone can maintain its polished appearance for a long time with sensible wear. Surface buildup can sometimes be mistaken for damage.
Is moissanite as hard as diamond?
No. Diamond is harder. Moissanite is still hard enough for regular fine-jewelry use.
Bottom line
Moissanite does not scratch easily. Protect exposed edges from hard impacts and store jewelry separately when it is not being worn.
