FEIKFEIZ Moissanite vs. Diamond: What's the Difference?
Introduction
If you’re shopping for an engagement ring, a thoughtful holiday gift or a meaningful piece of everyday jewellery, you’ve almost certainly found yourself comparing moissanite and diamond. It’s one of the most common questions from buyers across Europe, and it makes sense to seek out clear, unbiased facts before you commit to a piece you’ll wear for years.
You won’t find pushy sales language or pressure to pick one stone over the other here. We’re walking through the key differences across four core areas — brilliance and fire, hardness and durability, colour and clarity, and price — so you can make a choice that fits your budget, lifestyle and personal taste.
What is Moissanite?
Moissanite is a naturally occurring silicon carbide crystal, first identified by French chemist Henri Moissan in 1893 while he studied samples from Arizona’s Canyon Diablo meteor crater. Natural moissanite is exceptionally rare, found only in tiny trace amounts within meteorite deposits, so every moissanite used in modern fine jewellery is created in controlled laboratory environments.
Lab-grown moissanite shares the exact same physical and optical properties as its natural counterpart, with one key practical benefit — consistent, reliable quality across every single stone. Unlike mined diamonds, which vary dramatically in grade depending on the rough material, lab-grown stones can be produced to meet high colour, clarity and cut standards as standard, with no random quality drops.
Every moissanite stone used in FEIKFEIZ pieces comes with an official GRA certificate and a unique engraved black card, which lets you verify seven key details: carat weight, dimensions, colour grade (D-F-G), clarity (VVS/VS), cut, polish and symmetry. Full traceability means you know exactly what you’re getting, with no hidden compromises on quality.
In soft natural daylight, a well-cut moissanite shows a bright, lively sparkle that catches light from almost every angle, with subtle rainbow flashes that shift gently as you move.
Key Differences Between Moissanite and Diamond
Brilliance and Fire
Brilliance and fire are the two factors that define how a stone looks when light passes through it. Diamond has a refractive index of 2.42, while moissanite measures at 2.69 — a noticeably higher figure that translates to more visible fire, or the rainbow-coloured flashes you see when a stone moves through light.
In practice, the difference is subtle in most everyday settings. Under soft indoor light or overcast outdoor conditions, most people cannot tell the two apart with the naked eye. The stronger fire of moissanite becomes slightly more noticeable under direct, bright sunlight, but it remains a refined, elegant sparkle rather than an overwhelming one.
Hardness and Durability
Hardness, measured on the Mohs scale, determines how well a stone resists scratches and wear over time. Diamond sits at a 10, the highest possible score, while moissanite ranks at 9.25 — placing it well above most other gemstones used in everyday jewellery.
What this means for daily wear is that both stones hold up extremely well to regular use. Moissanite resists chipping and scratching from normal activities like typing, housework or occasional knocks against hard surfaces, making it a solid choice for daily-wear rings and bracelets.
All FEIKFEIZ jewellery is built with this daily use in mind. Pieces are crafted from hypoallergenic alloy and S925 sterling silver bases, finished with a thick layer of 18K gold or rhodium plating for long-lasting shine.
Every item passes heavy metal safety testing and meets EU REACH regulations. The low-sensitivity formula works well for those with easily irritated skin, so you can wear pieces comfortably from morning to evening without worry.
Colour and Clarity
Diamond colour is graded on a D to Z scale, with stones closer to the colourless D grade carrying a significant price premium. Mined diamonds also vary widely in clarity, with eye-clean stones costing much more than those with visible inclusions.
With lab-grown moissanite, high colour and clarity grades come as standard, regardless of carat size. You do not have to pay extra to get a near-colourless stone with no visible inclusions to the naked eye.
Every FEIKFEIZ moissanite piece uses stones graded in the D-F-G colour range and VVS/VS clarity, so you get a consistent, clean look across every price point. There’s no need to trade down on quality to stay within your budget.
Price
Price is where the most noticeable difference between the two stones appears. A mined diamond carries costs tied to extraction, global supply chains, independent certification and geological rarity, all of which add up to a much higher retail price for a comparable visual size and grade.
Moissanite, as a lab-created stone, avoids many of those layered supply chain costs. For a stone of similar face-up size and appearance, moissanite typically costs a fraction of the price of a mined diamond.
The budget you save can go toward a larger stone, a more detailed setting, or even a matching set of jewellery for gifting. For pieces intended for daily wear or occasional special occasions, moissanite offers strong value without sacrificing the look of a fine gemstone.

Frequently Asked Questions
Can you tell moissanite apart from diamond with the naked eye?
For most people, in everyday indoor and soft outdoor light, it is very difficult to spot a difference with the naked eye. The higher fire of moissanite becomes slightly more visible under very bright, direct sunlight, but the stone still reads as a clear, colourless gem to casual observers. Only trained gemmologists with specialised tools can reliably tell the two apart in all lighting conditions.
Is moissanite suitable for an everyday engagement ring?
Yes, it works very well for daily wear. With a Mohs hardness of 9.25, moissanite resists scratches and minor impacts from regular daily activities like typing, cooking or commuting.
FEIKFEIZ settings are also built for long-term daily use, with hypoallergenic bases and durable plating that holds up to regular hand washing and skin contact. The low-sensitivity materials mean you can wear the ring all day without irritation, even if you have easily reactive skin.
What kind of after-sales support and warranty comes with moissanite jewellery?
Every FEIKFEIZ purchase comes with a 30-day no-hassle return and exchange window, plus a 1-year official warranty covering manufacturing defects.
If you are sending a piece as a gift, the recipient can contact customer support directly using their parcel tracking number, without needing to reach out to the original buyer. This makes gifting simpler, as the person receiving the item can resolve any questions or issues independently.
