Does Moissanite scratch glass?
Yes.
Moissanite has a hardness of 9.25 on the Mohs scale, while common glass has a hardness between 5.5 and 6 .
This means that moissanite scratches glass easily.
Even with daily use, it maintains its integrity without scratching easily.
What the scratch test says about the stone
This simple test is used to show that the stone is strong and genuine .
Common brittle or synthetic stones will not scratch glass.
It's a handy way to quickly rule out counterfeits .
Comparison with other stones
Unlike zirconia or crystals, which are softer , moissanite is one of the hardest stones, second only to diamond ( hardness 10 ).
This makes moissanite ideal for jewelry that requires intense, long-lasting wear.
Can I use the glass test to identify moissanite?
Not alone .
Scratching glass proves high hardness , but can indicate either moissanite or diamond .
Other tests are needed to differentiate.
Thermal testing and optical analysis complement this diagnosis with greater precision.
Conclusion
THE moissanite is strong, durable and genuine .
Scratching glass is not a complete test, but it helps to understand its quality and resistance .
Even though it is not definitive, this test is a good first step in the evaluation.
