Few jewelry questions come up as often as this one: is moissanite just a 'fake diamond,' or is it a genuine choice in its own right? The short answer is the latter. Moissanite is a distinct gemstone with its own chemistry, its own kind of sparkle and its own very real advantages — especially for everyday jewelry you never want to take off. At Alexcraft, we set moissanite in solid 925 sterling silver precisely because it is tough enough for real life and luminous enough to feel special every single day.
This guide walks you through how the two stones compare on sparkle, hardness, price, ethics and upkeep, and ends with a simple framework for deciding. If you already know you want moissanite, you can browse our moissanite collection or the moissanite earrings range.
What Exactly Is Moissanite?
Moissanite is composed of silicon carbide. Natural moissanite is extraordinarily rare — it was first identified in a meteor crater — so virtually all moissanite used in jewelry today is grown in a controlled laboratory. That matters for two reasons: nothing has to be mined to create it, and every stone can be cut to a consistent, high standard. Rather than thinking of it as a diamond substitute, it helps to think of it as a lab-grown gem optimized for brilliance, durability and value. Our Still Light and moissanite pieces use bezel and secure settings designed to protect that brilliance for years.

Sparkle and Fire: Where Moissanite Stands Out
Diamond is prized for its white, restrained brilliance. Moissanite actually refracts more light: it has a higher refractive index and greater dispersion, which is the technical term for the rainbow 'fire' that flashes when a stone moves. In plain language, a moissanite tends to throw more colorful sparkle than a same-size diamond, especially in sunlight or warm indoor light. Some people fall in love with that extra fire instantly; others prefer the subtler, whiter look of diamond — it is a matter of taste, not quality. Modern, well-cut moissanite is nearly colorless, so the old stereotype of a 'greenish' stone no longer applies to today's material.
Hardness and Daily Wear
Diamond is the hardest known natural material at 10 on the Mohs scale; moissanite sits at about 9.25 — second only to diamond among common jewelry stones and well above sapphires in practical scratch resistance. In everyday terms, that means moissanite shrugs off the gym, hand-washing, sleeping in your jewelry and the occasional knock against a desk. It will not cloud, fade or scratch with normal wear the way softer gems (or glass imitations) do. That durability is exactly why we trust it in pieces meant to be lived in, from moissanite stud earrings to delicate stackable rings.
| Factor | Diamond | Moissanite |
|---|---|---|
| Composition | Carbon (mined or lab) | Silicon carbide (lab-grown) |
| Mohs hardness | 10 | ≈ 9.25 |
| Sparkle / fire | Bright white brilliance | Higher dispersion, more rainbow fire |
| Color | D–Z color grades | Near-colorless in modern grades |
| Price (same size) | High | A fraction of diamond |
| Ethics | Depends on sourcing | Nothing mined; fully traceable growth |
| Best for | Traditional investment piece | Everyday brilliance & value |
Lab-grown means nothing is mined — and each stone can be cut to a consistent standard
Price: The Honest Math
This is where the gap is largest. A moissanite costs a small fraction of a same-size diamond, which frees up budget for the things that actually affect daily enjoyment: a secure setting, a solid 925 sterling silver base, a comfortable fit and a second or third piece to layer with. For the price of one small diamond stud, you can often own a pair of moissanite earrings plus a matching pendant — and still have change left. That value is the core reason moissanite has become the stone of choice for everyday, 'never-take-it-off' jewelry.
Ethics and Sustainability
Because moissanite is lab-grown, there is no mining, no habitat disruption and no uncertain origin story. For buyers who care about where their jewelry comes from, that is genuinely reassuring. It pairs naturally with the rest of our approach: an eco-friendly recycled brass everyday metal, recyclable packaging and pieces designed to be kept for years rather than discarded after a season. You can read more about that philosophy on our materials page and in our note on quiet luxury.

Caring for Moissanite
Moissanite is low-maintenance. Warm water, a tiny amount of mild soap and a very soft brush around the setting will lift any buildup of skin oil or lotion; dry it completely afterward to avoid water spots. Avoid ultrasonic and ammonia-based cleaners, which can be hard on the metal finish around the stone. Because our moissanite sits in sterling silver (often finished in a warm 14K gold tone), the care routine is really the same as for the rest of your collection — our jewelry care guide walks through it step by step, and every piece is backed by our 5-year warranty.
So Which Should You Choose?
Choose diamond if you specifically want the traditional, whitest sparkle and view the piece as a long-term financial or heirloom purchase. Choose moissanite if you want maximum sparkle, serious durability, an ethical no-mining story and outstanding value in jewelry you genuinely wear every day. For most people building an everyday collection — and especially for earrings and delicate rings that live an active life — moissanite is the smarter, more wearable pick.

Frequently Asked Questions
Is moissanite a fake diamond?
No. It is a separate gemstone made of silicon carbide with its own optical properties. It is grown in a lab rather than mined, and it actually disperses more light — giving more rainbow fire — than diamond.
Will moissanite scratch or cloud over time?
At about 9.25 on the Mohs scale it is one of the hardest gemstones used in jewelry, so it resists everyday scratching and does not cloud. Simple soap-and-water care keeps it sparkling.
Does moissanite look noticeably different from diamond?
Modern near-colorless moissanite looks very similar, but tends to show slightly more colorful sparkle in strong light. The difference is subtle and for many wearers the extra fire is the appeal.
Why is moissanite so much cheaper?
Lab growth avoids the rarity, mining and distribution costs that drive diamond prices, so you pay for the stone's beauty and durability rather than its scarcity.
What metal does Alexcraft set moissanite in?
We set moissanite in solid 925 sterling silver, often finished in a 14K gold tone or bright rhodium, with secure settings built for daily wear and a 5-year warranty behind them.
Conclusion
Moissanite is not a compromise — it is a deliberate, modern choice: more fire than diamond, nearly as hard, ethically grown and dramatically better value. Set in solid 925 silver and worn every day, it may be the hardest-working stone in your jewelry box.
