What is moissanite and how is it different from a natural diamond?

Moissanite is a gemstone made of silicon carbide (SiC). While it's naturally occurring, the moissanite used in jewelry is lab-created. It's visually similar to diamonds but has a different chemical composition and optical properties, including a higher refractive index that results in more intense 'fire' or rainbow flashes. For more on comparing these stones, check out our article on Moissanite vs. Diamond: Your Guide to Choosing the Perfect Engagement Ring.

Are lab-grown diamonds real diamonds?

Yes, lab-grown diamonds are real diamonds. They are created in a controlled laboratory environment and share the exact same chemical, physical, and optical properties as natural diamonds because they are made of pure carbon.

Which is harder: moissanite or lab-grown diamonds?

Lab-grown diamonds are the hardest known material, ranking 10 on the Mohs scale. Moissanite is also very hard, ranking 9.25 on the Mohs scale, making both excellent choices for everyday wear.

How can a jeweler tell the difference between moissanite and a lab-grown diamond?

Jewelers often use diamond testers that measure thermal conductivity. Moissanite and diamonds have different thermal conductivity, which allows for differentiation. You can learn more about using these tools in our article on Unlocking Diamond Authenticity: Your Guide to Using a Diamond Tester Pen.

What causes the difference in sparkle between moissanite and lab-grown diamonds?

The difference in sparkle comes from their optical properties. Moissanite has a higher refractive index, leading to more intense and colorful flashes of light (fire). Lab-grown diamonds exhibit the classic diamond sparkle, indistinguishable from natural diamonds.

Is moissanite significantly cheaper than lab-grown diamonds?

Yes, moissanite is generally significantly more affordable than both natural and lab-grown diamonds of comparable size and quality. This makes it a very attractive option for those looking for a large, brilliant stone on a budget. For instance, the Ilyra - 3CT Moissanite Silver Ring offers substantial sparkle at a great value.

Do moissanite and lab-grown diamonds have inclusions?

Lab-grown diamonds can have inclusions similar to natural diamonds, which are often used for grading. Moissanite can have inclusions that appear as tiny needles or pinpoints, though they are typically very small and less noticeable.
