What Is Moissanite?

Moissanite is a laboratory-grown diamond simulant made from silicon carbide. It was first discovered in 1893 by French chemist Henri Moissan in the remnants of a meteor crater. Because natural Moissanite is incredibly rare, the Moissanite used in fine jewellery today are expertly created in laboratories, allowing them to achieve exceptional quality and consistency.

What Makes Moissanite Special?

Exceptional Brilliance

Moissanite has one of the highest refractive indexes of any gemstone used in jewellery, creating remarkable sparkle and flashes of rainbow light known as "fire." Many people notice that Moissanite appears even more vibrant than traditional diamonds under certain lighting conditions.

Made for Everyday Wear

Ranking 9.25 on the Mohs hardness scale, Moissanite is one of the hardest gemstones available, making it highly resistant to scratches and ideal for everyday jewellery.

Long-Lasting Beauty

Unlike many gemstone alternatives, Moissanite maintains its brilliance over time. It won't become cloudy or lose its sparkle with normal wear when properly cared for.

How to Care for Your Moissanite Jewellery

Clean Regularly

Daily wear can leave behind oils, lotions, sunscreen, and skincare products that reduce your jewellery's sparkle. Clean your Moissanite regularly using Eclat By Oui's Jewellery Foam Cleanser or warm water with a mild dish soap. Gently brush around the stone and setting with a soft-bristled brush, rinse thoroughly, and pat dry with a soft, lint-free cloth.

Remove During High-Impact Activities

Although Moissanite is exceptionally durable, we recommend removing your jewellery before activities such as weightlifting, contact sports, gardening, or moving heavy objects to help protect both the gemstone and its setting.

Avoid Harsh Chemicals

To preserve the beauty of your jewellery, remove it before using bleach, chlorine, or other harsh household cleaning products, as these may affect the metal and its finish over time.

Store It Properly

When not being worn, store your jewellery in a soft pouch or jewellery box to minimise scratches and prevent pieces from rubbing against one another.

Check Your Setting

If you wear your jewellery daily, we recommend having the setting inspected periodically to ensure your gemstone remains secure. A quick check can help keep your favourite pieces looking and performing their best for years to come.
