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.
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.
