Moissanite has exploded in popularity as an engagement ring stone and for good reason. It looks nearly identical to a diamond, costs a fraction of the price, and is one of the hardest gemstones on earth. This guide covers everything you need to make a confident, informed purchase.
What is Moissanite?
Moissanite (silicon carbide, SiC) is a naturally occurring and lab-created gemstone celebrated for its extraordinary brilliance and fire. It was first discovered in a meteor crater and today is grown entirely in controlled lab environments to gem-quality standards.
Key Properties at a Glance:
• Hardness: 9.25 on the Mohs scale (diamond is 10) — extremely scratch-resistant
• Refractive Index: 2.65–2.69 (higher than diamond's 2.42) — produces more sparkle
• Fire Dispersion: 0.104 (more than 2x that of diamonds) — vivid rainbow flashes
• Brilliance: Exceptional; often described as 'more sparkly' than diamond
• Durability: Resistant to heat, chemicals, and everyday wear
• Origin: 100% lab-grown; conflict-free and environmentally responsible
Bottom Line: Moissanite is not a fake diamond. It is its own gemstone with properties that, in some ways, surpass diamonds. The biggest practical differences are: moissanite shows more colorful sparkle (fire), while diamonds have a more classic white-light brilliance.
How Was Moissanite Discovered?
The story of moissanite begins in outer space. In 1893, Nobel Prize-winning chemist Dr. Henri Moissan was examining rock samples from a massive meteorite crater in Canyon Diablo, Arizona. He discovered tiny, brilliant crystals unlike anything he had seen before.
Initially, Dr. Moissan believed he had found diamonds. After years of analysis, he confirmed the crystals were silicon carbide a compound essentially unknown in nature at the time. The gemstone was later named Moissanite in his honour.
Natural moissanite is extraordinarily rare too rare for jewelry use. In the 1990s, Charles & Colvard developed a lab-growing process to create gem-quality moissanite crystals. They held a patent on the process until 2015, after which multiple manufacturers entered the market, bringing down prices significantly.
Moissanite vs Diamond
This is the question everyone asks. Here's a direct, honest comparison across the metrics that matter most:
Appearance
• To the naked eye: nearly identical for stones under 1 carat
• Sparkle type: Moissanite = more colorful fire; Diamond = more white brilliance
• Under strong light: Moissanite may show a slight 'disco-ball' effect in large stones
• Color: Premium moissanite is D–F colorless; older/cheaper stones may have a slight yellow or green tint
Durability
• Moissanite: 9.25 Mohs — harder than any natural gemstone except diamond
• Diamond: 10 Mohs — the hardest natural material
• Practical verdict: Both are completely suitable for everyday wear rings
• Moissanite will not scratch, chip, or cloud with normal wear
Price
• A 1-carat diamond (VS1, G color): $4,000–$8,000+
• A 1-carat equivalent moissanite (premium, D color): $300–$600
• Savings: 80–90% less than an equivalent-looking diamond
• Size for budget: You can get a 2-carat moissanite for the price of a tiny diamond
Ethics & Environment
• Moissanite: 100% lab-grown, zero mining impact, conflict-free by definition
• Diamond: Varies — lab-grown diamonds are also available; mined diamonds carry environmental and ethical risks
• For eco-conscious buyers, moissanite is a natural choice
Resale Value
• Diamonds: Retain some resale value (though far less than purchase price)
• Moissanite: Low resale value — but you paid far less to begin with
• Think of moissanite like a car: buy it for use and enjoyment, not investment
Why is Some Moissanite Less Expensive Than Other Moissanite?
Not all moissanite is created equal. Price differences come down to four main factors:
Factor 1 — Color Grade
• D–F (Colorless): The most expensive tier — completely clear, top quality
• G–I (Near Colorless): Slight warmth; very good value, nearly undetectable to eye
• J–K and below: Visible yellow or green tint — significantly cheaper, but noticeable
• Older moissanite generations had yellow/green tints. Modern moissanite is almost always D–F colorless.
Factor 2 — Manufacturer/Brand
• Charles & Colvard (Forever One): The original brand, premium quality, higher price
• Harro Gem, Brilliant Earth: High-quality with strong reputations
• Generic Chinese manufacturers: Often 50–70% cheaper, but quality is inconsistent
• Brand-name moissanite comes with certificates and quality guarantees; generic does not
Factor 3 — Size (Carat Weight)
• Moissanite is priced per stone (not per carat like diamonds), but larger stones cost more
• A 2ct moissanite is NOT double the price of a 1ct — the jump is smaller than diamonds
• Common sizes: 0.5ct equivalent (~$150–200), 1ct (~$300–500), 2ct (~$500–900), 3ct (~$700–1,200)
Factor 4 — Cut Quality
• Precision cuts maximise sparkle and command higher prices
• Poorly cut stones leak light and look dull — even at the same colour grade
• Always look for 'Excellent' or 'Ideal' cut grades

Tips for Buying Moissanite Rings
Use these expert tips to avoid common mistakes and get the most for your budget:
• Always buy D–F colorless: It costs a little more but eliminates any risk of a tinted stone. For white gold or platinum settings, colorless is essential.
• Go bigger than you would with diamond: Your budget allows it. A 2ct moissanite is spectacular and costs less than a 0.5ct diamond. Many buyers go 1.5–2.5ct.
• Choose the right metal pairing: White gold and platinum enhance the colorless sparkle. Rose gold adds warmth and pairs beautifully. Yellow gold suits vintage styles.
• Check the girdle thickness: A well-cut stone has a medium girdle — too thin chips easily; too thick adds weight without beauty.
• Read reviews with photos: Always look for customer photo reviews (not studio shots) to see real-life sparkle.
• Avoid Amazon for moissanite: Inconsistent quality, difficult returns, and no reliable certificates. Stick to dedicated jewelers.
• Consider the setting quality separately: A mediocre stone in a great setting can look better than a great stone in a cheap setting. Budget 30–40% for the setting.
• Size up if between sizes: Moissanite is slightly lighter than diamond. If you're between sizes, go slightly larger for visual impact.
