Lab-Grown vs. Moissanite vs. Cubic Zirconia: What’s the Difference?

When shopping for a diamond alternative, you’ll likely come across Lab-Grown Diamonds, Moissanite, and Cubic Zirconia (CZ). While they may look similar, they differ significantly in composition, brilliance, durability, and price. This guide will help you understand the key differences so you can make the right choice for your jewelry.

1. What Are Lab-Grown Diamonds?

Lab-grown diamonds are real diamonds, created in a controlled lab environment using advanced technology that mimics natural diamond formation. They have the same chemical composition, hardness, and brilliance as mined diamonds but are more sustainable and affordable.

Pros of Lab-Grown Diamonds:

✔️ 100% Real Diamond – Identical to natural diamonds in composition and structure.
✔️ More Affordable – 30-40% cheaper than mined diamonds.
✔️ Ethically Sourced – No environmental harm or unethical mining practices.
✔️ High Durability – Rated 10 on the Mohs hardness scale (same as natural diamonds).

Cons of Lab-Grown Diamonds:

❌ Not as Rare – Unlike natural diamonds, lab-grown diamonds can be produced in large quantities.
❌ Lower Resale Value – While still valuable, they don’t hold value like natural diamonds.

2. What is Moissanite?

Moissanite is a lab-created gemstone made of silicon carbide. While it resembles a diamond, it has a different composition and more fire and brilliance than both natural and lab-grown diamonds.

Pros of Moissanite:

✔️ High Brilliance – More fire and sparkle than diamonds.
✔️ Durable – Rated 9.25 on the Mohs scale, making it extremely scratch-resistant.
✔️ Budget-Friendly – More affordable than lab-grown diamonds.
✔️ Eco-Friendly – Created in a lab, making it a sustainable choice.

Cons of Moissanite:

❌ Different Sparkle – Some buyers find its rainbow-like sparkle less natural than a diamond.
❌ Not a Diamond – Although stunning, it is a distinct gemstone, not a diamond alternative.

3. What is Cubic Zirconia (CZ)?

Cubic Zirconia is a synthetic stone made from zirconium dioxide. It is the most affordable diamond simulant but lacks the durability and brilliance of diamonds and moissanite.

Pros of Cubic Zirconia:

✔️ Extremely Affordable – A fraction of the cost of diamonds and moissanite.
✔️ Diamond-Like Look – Mimics diamonds to the untrained eye.
✔️ Variety of Colors – Available in different hues for unique designs.

Cons of Cubic Zirconia:

❌ Less Durable – Rated 8 on the Mohs scale, making it prone to scratches and wear.
❌ Lower Sparkle – Doesn’t have the same brilliance as moissanite or diamonds.
❌ Clouds Over Time – Can lose its shine and develop a dull appearance with prolonged wear.
