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.

Prettier than the picture. Super durable and the sparkle is remarkable. Wear it more than my real wedding ring.
C
I purchased a size 6 in 1.5 carats. This ring fits perfectly and the clarity and brightness is so realistic. It looks just like a replica of Tiffany & Co. ring.
j
I’ve been wearing this ring to work and out and it’s still beautiful after two months. I’m a diamond girl, but too afraid to wear the real stuff while out. This is a great alternative.
K
Beautiful. I paired it with my anniversary band and wedding band. Love how it looks. GRA is fabricated and they tend to toot their own horn on the specs of the stone.Beautiful yes. But don't fall for the extra fluff. Buy it because you want a pretty thing
J
I gave this 5 stars as this is a beautiful ring, elegant and simple. Matches perfectly with my comfort fit band. I did have to get a smaller size, the 6.5 was too large, the size 6 fit best.
C
Beautiful ring! Brilliant color and clarity, fits well, looks like a nice diamond, but it's quality moissonite! Nicely packaged and includes GRA information/certificate.
M
Moissanite ring is on the top, diamond ring below. Perfect dupe for the real thing. Great for work, travel and in between cleanings. Just beautiful. So far holds up to working and handwashing. I have had this less than a month but activities would have warranted scratches already. Will update if quality issues come up.
L
True to size, I bought the 1.5 and paired it with a 4mm stainless steel comfort fit band that go together perfectly for me. I would rather wear the Moissanite diamonds for fun than my regular diamonds.
g
Looks very nice ,it does seem a little light weight, nice sparkle,baught a ring from the same company to wear with it, true to size,will keep updated about the stones
C
Due to an injury I cannot currently wear my E ring and wanted something that looked really good but didn't break the bank to wear until my finger recovers. Having read some good things about Aimilee moissanite rings online and upon seeing that this ring was on sale with same day delivery, I decided to take a chance on this very affordable ring. Sizing is on point, the stone is gorgeous and both the band and the setting are more substantial that I anticipated. I love the fact that the setting allows me to stack this ring nicely alongside my eternity band yet doesn't stand too tall, helping to make it more wearable as an every day ring. Early days but all in all I am very, very pleased with my purchase. Will report back if anything changes.
k
Beautiful. Looks exactly like my 1 ct real diamond solitaire ring in a 6 prong setting!
J
A very beautiful ring.
N
The ring is beautiful and matches the description, videos and pictures from the other reviews. Unfortunately the fit isn't as I hoped so I will be returning it. I learned that I don't care for a round setting and it sits high which could be an issue for catching the ring on things. Other than that it met my expectations. I hope this review helps someone.
M
Update from previous review (11/25/25) disappointed... after daily wear, the coating has started to chip and peel off. I still love it but it's sad that they coat the silver like this.Absolutely beautiful stone! The cut and clarity are amazing! 1.5 ct stone is worth every $ spent on it! The band isn't too thick and I think it will hold up to the daily wear and tear!
C
This ring looks and feels identical to my $10K one-carat diamond solitaire white gold ring. We tried eight similar rings and THIS ONE IS PERFECT!
L
Beautiful ♥️ I looked at SO many rings at different prices, compared reviews and decided on the Aimilee moissanite 3 CT solitaire rings. It's perfect!!! The 6 prong setting looks like Tiffany without the price point. Very happy with my purchase. If you want the classic solitaire look, this is the ring for you.
T
Very pretty and feminine. I love the smaller stones and the fact that the prongs don't stick up high enough to rub my other fingers. I've worn it for 3 days straight and showered and washed dishes with it and it still sparkles and shines. I got an 8.5 and thought it would fit my thumb, but it's about a half size too small for my thumb. It's very comfortable on my index finger though.
R
I bought this ring as a backup for my wedding ring. It didn’t tarnish or smell like some jewelry does. I didn’t take it off for 6 months and it looks as good as new! The value was amazing!
F
I bought this 2 1/2 carat dupe ring for my trip and I’ve gotta say it did great! It did not turn my finger green or any of the things you might be concerned about with buying a ring online.I felt a lot more confident traveling without my actual engagement ring and this did the job. The only thing I’m sad about is I couldn’t find it when I got home again. Again, I would much rather have misplaced this ring than my real ring. Here was hoping I find it soon!
e
Got this as a travel ring and it’s great quality! The band measures about 3.3mm for anyone curious
C
Very pretty and expensive looking.
B
It’s beautiful !!!! Love it !!! Well worth it !!!
S
Super Satisfied
P
I happy with this ring. It's beautiful. Only thing I ordered size 8 so I could wear it on my index finger & it was too small.
