Moissanite Guide
Moissanite, Explained.
Clear answers to the questions shoppers ask most about moissanite, from durability and brilliance to long-term care.
Is moissanite a real gemstone or a fake diamond?
Moissanite is a real gemstone with its own chemical composition and optical properties. It is not a type of diamond or a fake diamond.
Modern jewelry-grade moissanite is lab-created for consistency and clarity, with a distinctive brilliance and fire of its own.
What is the difference between moissanite and diamond?
Moissanite and diamond are different gemstones. Diamond is carbon, while moissanite is silicon carbide.
Visually, moissanite often displays more colorful fire, while diamond has its own characteristic balance of white brilliance and dispersion. Both can appear bright and refined, but their optical character is not identical.
Is moissanite durable enough for everyday wear?
Yes. Moissanite measures approximately 9.25 on the Mohs hardness scale, making it highly resistant to scratching and well suited to regular wear.
As with all fine jewelry, the setting and metal should still be protected from hard impacts, abrasive surfaces and strenuous activities.
Does moissanite get cloudy or lose its brilliance over time?
Moissanite does not normally become permanently cloudy with wear. Oils, lotions, soap and everyday residue can temporarily soften its sparkle.
Gentle cleaning can restore its clarity and brilliance, while regular care also helps keep the surrounding metal and settings looking their best.
How should I clean and care for moissanite jewelry?
Clean moissanite jewelry with lukewarm water, mild soap and a soft brush, then rinse thoroughly and dry with a soft, lint-free cloth.
Pay particular attention to the underside of stones and around settings where residue may collect. When not being worn, store your piece separately in its original STDIAM walnut wood box to help reduce contact and rubbing against other jewelry.
For more detailed guidance, visit the STDIAM Jewelry Care Guide .
Why is moissanite more affordable than diamond?
Moissanite follows a different production, supply and pricing structure from diamond. Because jewelry-grade moissanite can be created in a controlled laboratory environment, it can offer substantial visual presence and durability at a lower price point.
The lower price does not make it a lower-quality version of diamond. It is a different gemstone category with its own characteristics.
Can people tell the difference between moissanite and diamond?
The difference can be subtle at a glance, especially once a stone is set in jewelry, but moissanite and diamond are not visually identical.
Moissanite generally shows stronger spectral fire, while diamond has its own characteristic pattern of brilliance. Cut, stone size and lighting can all influence how noticeable those differences appear.
Is moissanite suitable for engagement rings and meaningful jewelry?
Yes. Moissanite combines high durability, distinctive brilliance and a wide range of cuts and settings, making it suitable for engagement rings as well as jewelry chosen for anniversaries, milestones, gifting or everyday wear.
Ultimately, the right choice comes down to the design, materials and character that feel right for you.

Perfect replica of my fiancee's engagement ring to bring traveling
V
Very beautiful. The stone is raised enough that you could wear a wedding band. I had tried cubic zirconium rings before but they looked waaay too fake. This one looks fantastic! And I hear this kind of stone is super durable.
J
Franchement, je suis trop contente de mon achat ! J'hésitais un peu au début, mais la bague est juste magnifique en vrai. La pierre brille énormément, honnêtement on ne voit pas la différence avec un vrai diamant. Il a fallu attendre une petite semaine pour la fabrication, mais l'attente valait clairement le coup

¡Estoy obsesionada con este anillo! Mi diamante auténtico está en reparación, y este sustituto es absolutamente deslumbrante y muy realista. La calidad es increíble, brilla de una manera preciosa y he recibido innumerables elogios; ¡incluso el gerente de la joyería se dejó engañar! La claridad es impecable y la talla 6.5 me queda perfecta. ¡No te arrepentirás de esta compra! 💍✨
