Moissanite is its own brilliant gemstone — not an imitation diamond. It throws even more fire than a diamond, rates 9.25 on the Mohs scale for confident daily wear, and costs a fraction of the price. Every IfShe moissanite is lab-created, conflict-free and clearly disclosed.
Frequently asked questions
How is moissanite different from a diamond?
Moissanite has a higher refractive index than diamond, giving it more rainbow fire. It measures 9.25 on the Mohs scale (vs diamond's 10) and costs a fraction of the price for an equivalent visual size. It is a lab-created gem chemically distinct from diamond.
Will moissanite cloud or fade over time?
No. Moissanite does not cloud, yellow, or lose brilliance. Its sparkle is permanent and does not require special restoration over the years.
Is moissanite durable enough for everyday wear?
Yes. At 9.25 on the Mohs scale, moissanite is the second-hardest known gemstone after diamond, so it resists scratches and keeps its sparkle through daily wear.
What setting metal do you offer?
Our moissanite pieces are set in 925 sterling silver; a few designs add a plated finish, such as gold-tone, over the silver. Each product page lists its metal, and where a silver or gold choice is offered, it appears in the options.
How do I clean my moissanite jewellery?
Soak in warm water with a few drops of mild dish soap, gently brush with a soft toothbrush, and rinse. Pat dry with a lint-free cloth. Avoid harsh chemicals and ultrasonic cleaners.
