What is Moissanite? Everything You Need to Know Before You Buy
If you've been jewellery shopping lately, whether browsing Instagram or walking through a mall in Mumbai, Delhi, or Bangalore, you've probably seen the word Moissanite pop up everywhere. It sparkles like a diamond, costs a fraction of the price, and people genuinely cannot stop talking about it.
But what exactly is Moissanite? Is it real? Is it just a fancy name for fake diamonds? Is it actually worth buying?
Let's break it all down, no jargon, no fluff.
The Origin Story: A Gemstone Literally Born from the Stars
Moissanite has one of the most fascinating origin stories in the gemstone world.
In 1893, French chemist Henri Moissan was examining fragments from a meteorite crater in Canyon Diablo, Arizona, when he discovered tiny, glittering crystals. He initially thought he'd found diamonds. Years later, in 1904, it was confirmed that these crystals were actually silicon carbide, a completely different compound, and the mineral was named Moissanite in his honour.
Here's what makes that remarkable: Moissanite is, quite literally, a gemstone from outer space. It is one of the rarest naturally occurring minerals on Earth, found almost exclusively in meteorites and, in trace quantities, in the Earth's upper mantle.
Because natural Moissanite is too scarce to be mined commercially, virtually all Moissanite used in jewellery today is grown in laboratories using advanced technology. And far from being a drawback, that's actually one of its biggest selling points, but more on that shortly.
What is Moissanite Made Of?
Moissanite is a crystalline form of silicon carbide (SiC). This is a completely different chemical composition from diamonds, which are made of pure carbon.
Because of this unique structure, Moissanite has its own distinct set of physical and optical properties, properties that, in some ways, actually surpass those of diamonds.
The Key Properties of Moissanite
1. Hardness & Durability
On the Mohs Scale of Hardness, the global standard for measuring a gemstone's resistance to scratching, Moissanite scores 9.25 out of 10. Diamonds sit at 10, making them the hardest natural material known to science.
That 0.75 difference? Almost irrelevant in practical, daily life. Moissanite is extraordinarily scratch-resistant and suitable for everyday wear, including rings, bracelets, and earrings that face constant contact and friction. It does not chip easily and holds up beautifully over decades.
2. Brilliance & Fire (The Sparkle Factor)
This is where Moissanite genuinely outshines diamonds, quite literally.
Moissanite has a refractive index of 2.65–2.69, compared to a diamond's 2.42. A higher refractive index means more light bends as it enters and exits the stone, creating more flashes of colour, known as fire.
To put it plainly: Moissanite produces more rainbow-coloured sparkle than a diamond. Some people adore this effect, it looks spectacular in sunlight and under indoor lighting. Others prefer the cooler, more restrained white brilliance of diamonds. Both are valid preferences, but if you want a stone that lights up a room, Moissanite delivers in a way very few gemstones can.
3. Colour
Modern Moissanite is available in the D–F (colourless) range, equivalent to the finest colour grades in diamonds. Earlier generations of Moissanite had a slight yellowish or greyish tint, but today's lab-grown stones are virtually indistinguishable from colourless diamonds to the naked eye.
Larger stones may occasionally show a very faint warm undertone under specific lighting, something worth knowing before purchasing a 3-carat solitaire, but rarely an issue for standard sizes.
4. Clarity
Lab-grown Moissanite is produced in controlled environments, which means inconsistencies like inclusions and blemishes are minimised from the start. Most Moissanite stones on the market fall in the VVS (Very Very Slightly Included) clarity range, exceptional even by fine jewellery standards.
Is Moissanite a Fake Diamond?
This is the most common misconception, and it needs to be cleared up.
Moissanite is not a fake diamond. It is a real gemstone.
It has its own chemical composition, its own set of physical properties, and its own distinct optical personality. It is not a diamond simulant in the way that cubic zirconia (CZ) or American diamond (AD) is. CZ is significantly softer, loses its lustre quickly, and does not remotely compare to Moissanite in durability or brilliance.
Moissanite is simply a different gemstone, one that happens to look strikingly similar to a diamond while offering its own set of advantages. Even experienced jewellers cannot tell Moissanite apart from diamonds with the naked eye. Specialised equipment, such as a Moissanite tester that measures electrical conductivity, is required to tell them apart.
Moissanite vs. Diamond: A Quick Comparison
| Feature | Moissanite | Diamond |
|---|---|---|
| Composition | Silicon Carbide (SiC) | Pure Carbon (C) |
| Natural / Lab Origin | Mostly lab-created (natural extremely rare) | Natural diamonds mined from the earth or lab-grown diamonds |
| Hardness (Mohs Scale) | 9.25 | 10 (hardest natural mineral) |
| Durability for Jewellery | Very durable for daily wear | Most durable gemstone for jewellery |
| Brilliance (Light Return) | Higher brilliance than a diamond | Slightly less brilliance |
| Fire (Rainbow Sparkle) | Very high fire (more rainbow flashes) | Balanced white sparkle with some fire |
| Refractive Index | 2.65 – 2.69 | 2.42 |
| Dispersion | 0.104 (very fiery) | 0.044 |
| Appearance | Slight rainbow sparkle; sometimes looks “too sparkly” | Classic natural white sparkle |
| Clarity | Usually flawless or near-flawless | Can have inclusions depending on grade |
| Color Range | Near-colourless to colourless | D–Z color scale used in diamond grading |
| Weight (Density) | Less dense; looks larger per carat | More dense |
| Price | 80–95% cheaper than diamond | Much more expensive |
| Typical 1 Carat Price | ~₹300 – ₹600 | ~₹5,0000 – ₹15,000+ depending on quality |
| Heat Resistance | Very high | Extremely high |
| Scratch Resistance | Very high but slightly less than diamond | Highest scratch resistance |

| Popularity in Engagement Rings | Growing alternative | Global standard |
The price difference alone is staggering. A 1-carat natural diamond can cost upwards of ₹3–6 lakh, while a comparable Moissanite of excellent quality can be had for ₹8,000–₹20,000. That's a saving of 70–90%, enough to go considerably larger in stone size, invest in a far more intricate setting, or simply spend wisely.
Why is Moissanite Growing So Fast?
The jewellery market is undergoing a genuine shift. A new generation of buyers, particularly urban millennials and Gen Z consumers in cities like Mumbai, Pune, Hyderabad, Bengaluru, and Delhi, is rethinking what luxury means.
They want pieces that look extraordinary, last a lifetime, and don't come with an ethical question mark attached. They're also smart about money. They understand that paying ₹5 lakh for a diamond when an equally stunning stone exists for ₹15,000 isn't status, it's just outdated marketing.
Moissanite fits this shift perfectly. It offers:
- Undeniable visual impact, the sparkle is real, dramatic, and permanent
- Long-term durability, it doesn't cloud, tarnish, or fade over time
- Ethical certainty, lab-grown, conflict-free, with a minimal carbon footprint
- Significant affordability, allowing buyers to access designs and sizes they'd never consider in diamonds
Does Moissanite Last Forever?
Yes. Moissanite does not degrade, lose its brilliance, or cloud over time. Unlike lower-quality stones like CZ, which dull and scratch within months, Moissanite retains its fire and clarity permanently. A Moissanite stone bought today will look just as spectacular in 20 years, provided the setting and metal are of good quality.
Which brings us to something equally important.
The Metal Matters as Much as the Stone
Here's a truth most jewellery brands won't tell you: a spectacular stone set in a poor-quality metal is still poor-quality jewellery.
Moissanite deserves a setting that matches it, something that elevates its brilliance, holds its structure for years, and feels like genuine luxury against the skin.
That's exactly what KYMEE's 18K Gold Vermeil delivers.
Why KYMEE's 18K Gold Vermeil is the Perfect Pairing for Moissanite
Gold Vermeil (pronounced ver-may) is a specific, high-quality method of gold finishing: a thick layer of real 18-karat gold bonded over a 925 sterling silver base. This is not gold-plated. It is not costume jewellery. It is a hallmarked, regulated standard of fine jewellery that gives you the warmth, weight, and richness of gold at a price that makes sense.
When KYMEE pairs Moissanite with 18K Gold Vermeil, here's what you're actually getting:
Real gold. Real sparkle. Real value.
The 18K gold surface gives Moissanite exactly the warm, luxurious backdrop it deserves, whether it's a classic solitaire ring, a layered necklace, stackable bracelets, or statement earrings. The 925 sterling silver base ensures the piece has proper structure and weight, while the 18K gold layer ensures it looks and feels premium.
KYMEE's Moissanite-set gold vermeil pieces are designed for the woman who doesn't compromise. She wants jewellery that photographs beautifully on a phone, holds up at the office, and looks just as stunning at a wedding. She wants to wear it every day without worrying about it.
That's the KYMEE promise.
How to Care for Your Moissanite Jewellery
Moissanite is remarkably low-maintenance, but a few simple habits will keep your pieces looking their best:
- Clean gently with mild soap, warm water, and a soft-bristle brush every few weeks. Oils from skin, lotions, and cosmetics can temporarily dull the surface.
- Store separately in a soft pouch or lined jewellery box to avoid contact scratches on other pieces.
- Remove during heavy activity, not because Moissanite can't handle it, but to protect the setting and the metal.
- Avoid harsh chemicals like bleach or acetone, especially with gold vermeil settings.
Beyond that, Moissanite simply does not require the intensive care or anxiety that comes with wearing extremely expensive fine jewellery. You can actually enjoy wearing it.
Final Thoughts
If you're looking for a gemstone that sparkles brilliantly, lasts a lifetime, comes from an ethical source, and lets you wear something genuinely beautiful without financial strain, Moissanite is not just worth it. It might be the smartest jewellery decision you make.
The question is no longer why Moissanite. The question is: which piece do you start with?

FAQs
1. Can a jeweller tell it's not a diamond?
Not without specialised equipment. To the naked eye, even for a trained jeweller, Moissanite and diamond look identical. Only a dedicated Moissanite tester can reliably distinguish them.
2. Is Moissanite certified?
Yes. Quality Moissanite stones come with certifications from recognised gemological labs (IGC, SGL, etc.) confirming colour, clarity, and authenticity. Always buy certified.
3. Will it lose its sparkle?
No. Moissanite retains its optical properties permanently. It does not cloud, scratch easily, or fade.
4. Is it better than CZ or American Diamond?
Significantly. CZ scores just 8–8.5 on the Mohs scale, loses its lustre within months, and cannot pass a thermal conductivity test the way Moissanite can. The two are not remotely comparable in quality or longevity.
5. Is gold vermeil real gold?
Yes. Gold vermeil is a regulated standard requiring a minimum gold purity (18K in KYMEE) bonded to a 925 sterling silver base. It is real gold jewellery, hallmarked and certified
