Moissanite is a rare mineral composed of silicon carbide that was first discovered in a meteorite by Henri Moissan in 1893. While initially mistaken for diamonds, natural moissanite is extremely scarce, having only been found a handful of times in the Earth's upper mantle. Today, all moissanite used in jewelry is grown in laboratories, offering a traceable, environmentally friendly alternative to mined gems. With its increasing popularity, moissanite has become a sought-after choice for engagement ring center stones and other jewelry applications.

Moissanite is a versatile gemstone that can be cut into a wide variety of shapes to suit different styles and preferences. Some of the most popular shapes for moissanite include as round, oval, princess, cushion, pear, emerald, and radiant cuts. Each of these shapes has its own unique characteristics and can be used to create different styles of jewelry. For example, round and cushion cuts are classic and timeless, while princess and pear cuts are more modern and edgy. Emerald and radiant cuts are popular for their elegant and sophisticated appearance, while oval cuts are known for their elongating effect on the finger.

Moissanite ranks impressively high on the Mohs scale of hardness, scoring a 9.25 out of 10, just under diamonds which score a 10. This makes moissanite very suitable for everyday wear, resisting scratches and abrasions well.

Moissanite comes primarily in colorless forms, but you can also find it in shades like yellow, green, and blue. These colored stones are specially treated to bring out vibrant, unique hues that can accentuate any piece of jewelry.

Yes, moissanite is an extremely versatile stone that can be set into rings, earrings, necklaces, and bracelets. Its durability, brilliance, and affordability make it a favored choice for various jewelry settings at Brilliant Earth.

Moissanite is a very stable and durable gemstone. It will not become cloudy or lose its sparkle over time. Like any jewelry, it can accumulate oils and dirt from daily wear, which might temporarily reduce its brilliance, but regular cleaning will easily restore its sparkle.

Moissanite is easy to clean. You can maintain its brilliance by regularly soaking your jewelry in warm water with a few drops of mild dish soap. Gently scrub the stone and setting with a soft toothbrush, then rinse thoroughly with warm water and dry with a lint-free cloth. For a deeper clean, you can use a commercial jewelry cleaner or an ultrasonic cleaner. It's also recommended to have your moissanite jewelry professionally inspected and cleaned periodically to ensure the setting remains secure.
