Moissanite vs. Lab-Grown vs. Natural Diamonds: How to Choose Your Center Stone

what's the difference between moissanite and lab diamond

Here’s a clear, local guide from Farsi Jewelers in Sandy Springs—serving Metro Atlanta—to help you decide what’s right for your ring: moissanite, lab-grown diamond, or natural diamond.

2026 update: Lab-grown diamond prices have fallen so far that a real lab-grown diamond now costs close to what moissanite used to. For most couples we work with in Sandy Springs, that has made lab-grown the smarter pick — a genuine diamond at a near-moissanite price. Moissanite is still a great budget option, and we can create it by special order. Here’s how to choose.

Quick Comparison

  • Moissanite: Very bright, lowest price, different optical look than diamond, very durable.
  • Lab-grown diamond: Real diamond, same hardness and sparkle as natural, now priced close to moissanite — the best value for most couples.
  • Natural diamond: Traditional rarity and long-term heritage, broad range of qualities and prices.

Moissanite vs. Lab-Grown Diamond

Many couples in Sandy Springs and Atlanta ask us about the difference between moissanite and lab-grown diamonds. While they can look similar at first glance, they are very different stones:

  • Composition: Lab-grown diamonds are pure carbon, identical to natural diamonds. Moissanite is made of silicon carbide, giving it unique optical properties.
  • Sparkle: Moissanite often shows a rainbow-like sparkle (called “fire”), while diamonds—lab or natural—show a classic white brilliance.
  • Hardness: Diamonds are the hardest material on earth (10 on the Mohs scale). Moissanite is also extremely durable at ~9.25, making it excellent for daily wear.
  • Price: Moissanite is still the most affordable, but the gap has narrowed dramatically — lab-grown diamond prices have dropped close to moissanite levels, while staying far below natural diamonds of the same size and quality.

If you want a real diamond at a price that used to only buy moissanite, lab-grown is now the value winner for most couples. If you want the absolute lowest price or moissanite’s extra rainbow fire, moissanite is still worth exploring — and we can source it by special order.

Which Fits Your Priorities?

Best overall value: lab-grown diamond.
Lowest price: moissanite.
Classic tradition: natural diamond.
Everyday durability: all three perform well; diamond is the hardest (10), moissanite ~9.25.

Expert Insight

“Five years ago I steered budget-minded couples toward moissanite. Today, with lab-grown prices where they are, I usually point them to a lab-grown diamond — it’s a real diamond for nearly the same money. Seeing them side by side in the builder makes the decision easy.” — Kam, GIA Graduate Gemologist

FAQs for Sandy Springs & Atlanta Couples

Is moissanite still worth it in 2026?
Moissanite is still a beautiful, durable, budget-friendly stone. But because lab-grown diamond prices have fallen so close to moissanite, most couples now get better long-term value from a real lab-grown diamond. We’re happy to show you both and still make moissanite rings by special order.
Is moissanite as durable as diamond?
Yes. Moissanite is ~9.25 on the Mohs scale, which makes it highly durable for daily wear. Diamond is harder at 10, but both are excellent for engagement rings in Atlanta’s active lifestyle.
Do lab-grown diamonds test as real diamonds?
Yes. Lab-grown diamonds are chemically, physically, and optically identical to natural diamonds. They pass diamond testers and are graded by the same standards used for natural stones.
Are lab-grown diamonds popular in Sandy Springs and Atlanta?
Absolutely. Over the last few years, lab-grown diamonds have become one of the most popular choices for engagement rings in Metro Atlanta because they offer the same beauty as natural diamonds at a much lower price point.
How do I care for moissanite or lab-grown diamonds?
Both moissanite and lab-grown diamonds are easy to care for. Clean them at home with mild dish soap and warm water, or bring them to Farsi Jewelers in Sandy Springs for professional ultrasonic cleaning and inspection. Regular maintenance ensures long-lasting brilliance.
Can I compare them in person at your Sandy Springs store?
Yes—our custom ring builder lets you try different sizes, shapes, and stones side by side. This is the best way to see moissanite and lab-grown diamonds up close before deciding which one suits your style and budget.
