Does moissanite scratch easily?

No. At 9.25 on the Mohs scale, moissanite is the second hardest gemstone in common jewellery use. Nothing in normal daily life will scratch it.

The direct answer — no

Moissanite does not scratch easily. At 9.25 Mohs, only diamond (10) or other moissanite (9.25) can scratch it. Keys, coins, glass, countertops, metal surfaces — all softer than moissanite and cannot cause any scratch.

Material	Mohs Hardness	Can It Scratch Moissanite?
Diamond	10	Yes — the only common material that can
Moissanite	9.25	By diamond or other moissanite only
Sapphire / Ruby	9	No
Steel tools	6–7	No
Glass	5.5	No
Keys	5–6	No
Coins	3–4	No

“In 9+ years of working with gemstones, I have never seen a moissanite scratched by anything other than another diamond in daily wear conditions.”
— Yash Chandpara, Founder

What CAN scratch moissanite

Only diamond and other moissanite. In practical terms, this means:

Practical precautions

Store moissanite jewellery separately from diamond jewellery — if they contact each other, both can be scratched
Do not store moissanite pieces touching each other
These precautions are identical to those recommended for diamond jewellery

Moissanite vs other gemstones — scratch resistance

Gemstone	Mohs	Daily Wear Scratch Resistance
Diamond	10	Exceptional
Moissanite	9.25	Exceptional — second only to diamond
Sapphire / Ruby	9	Excellent
Topaz	8	Good
Emerald	7.5	Moderate — develops surface scratches over years
White Sapphire	9	Excellent hardness but low optical quality

Scratch questions answered

Will everyday activities scratch my moissanite?

No. Cooking, typing, exercising, cleaning, gardening with regular tools — none of these activities involve materials hard enough to scratch moissanite. The stone is exceptionally resistant to everyday contact.

What about the ring setting?

The gold or platinum band and setting will develop micro-scratches from daily wear — this is normal for any fine jewellery metal. The stone will not be affected. Periodic professional polishing restores the band surface.

Should I remove the ring for any activities?

Remove for heavy gym sessions (prong wear from metal bars), pool swimming (chlorine affects gold), and heavy chemical cleaning — the same guidance as for diamond rings. Not because the stone will scratch, but to protect the setting.
