Moissanite Engagement Rings: A Guide to Brilliance and Sustainability

Learn more about the beauty and brilliance of moissanite engagement rings, including the best cuts, settings, and where to find gorgeous moissanite.

The Fascinating History of Moissanite

Moissanite is a rare, naturally occurring mineral often referred to as the “gemstone of the stars.” In 1893, French scientist Dr. Henri Moissan discovered moissanite within a meteorite crater in Arizona. Initially, Dr. Moissan believed these hard, brilliant stones were diamonds. However, nine years later, he realized they were not composed of carbon, like diamonds, but rather of silicon carbide. 

Natural moissanites are incredibly rare, with only a handful of deposits found throughout history. Most of the brilliant moissanites you see are grown in a lab. Moissanite, along with lab-grown diamonds, has a minimal carbon footprint and reduced environmental impact. 

Modern moissanite gemstones are adored for their durability and radiant appearance. Not to mention, moissanite is often less expensive per carat than many other gemstones. This article will cover the unique properties of moissanite engagement rings and offer expert guidance on moissanite’s most beautiful cuts and settings. 


The Science of Sparkle

Moissanite has unique optical properties that contribute to its exceptional shine and shimmer. 

Refractive Index

Refractive Index (RI) is the amount of light that shines off a stone. It’s the most significant optical property affecting a gemstone’s brilliance or sparkle. The RI of moissanite is 2.69, meaning it displays slightly more brilliance than diamond (with an RI of 2.42) or any other popular gemstone.

Fire Dispersion

Also known as gemstone dispersion, fire refers to the prism effect of pure white light entering a gem, breaking into spectral colors, and reflecting back to the viewer. Moissanite’s dispersion is 0.104, which exceeds that of many gemstones, including rubies, sapphires, and emeralds. Moissanite creates flashes of rainbow lights that add a captivating sparkle to your engagement ring. The reason behind the radiance is fascinating and showcases the special benefits of moissanite stones.

Mohs Hardness Scale

With a hardness of 9.25-9.50, moissanite is harder than all other gemstones except diamonds, which are a 10 on the Mohs Hardness Scale. Most fine jewelry wearers won’t notice a difference between the hardness of diamonds and moissanite.


The Ethical Choice

In the late 1950s, scientists discovered how to create moissanite in a lab. The process of making one moissanite stone from silicon carbide crystals takes two to three months and produces minimal environmental waste. This makes moissanite a great option for fine jewelry with few ethical or environmental concerns. 

Not all mined diamonds come from troubling beginnings, but unfortunately, some traditional diamonds are not farmed ethically. At Olive Ave Jewelry, we’re committed to providing ethically sourced materials. All Olive Ave stones, including natural diamonds, are guaranteed to be ethical and environmentally friendly. 

Still, the minimal environmental impact and the per-carat value of moissanite attract many newly engaged shoppers. All Olive Ave moissanite center stones come with a Limited Lifetime Warranty that applies to purchases 4mm in size or larger and confirms our commitment to excellence.

Hardness and Toughness

Moissanite is durable, tough, and extremely resistant to scratching and abrasion. With a hardness of 9.25-9.50, moissanite is harder than all other gemstones except diamond.

Moissanite exhibits more heat resistance than many other gemstones, including diamond. Tests prove that at 2,000ºF–higher than the equivalent intensity of a house fire–moissanite gems remain intact and as brilliant as the day they were created. This heat tolerance makes moissanite unlikely to suffer damage during jewelry repair.

Caring for Your Moissanite Engagement Ring

Moissanite is durable and tough and extremely resistant to scratching and abrasion. However, some maintenance is necessary to ensure your ring’s lasting beauty. 

  • Regular Cleaning: Clean your moissanite ring every three to four weeks to prevent the buildup of oils and dirt. You can make a simple cleaning solution by mixing the Olive Ave Cleaning Kit packet into water. Then, gently clean your ring with a soft brush. Rinse under running water and dry with a soft cloth.
  • Personal Inspection: Check over your ring every once in a while to ensure it’s in top shape and is not in need of maintenance.
  • Avoid Harsh Chemicals: Moissanite is durable, but chemicals can damage the metal setting. Remove your ring before using harsh cleaners or chemicals. 
  • Polishing: Over time, the metal band might lose its shine. Use a jewelry polishing cloth to maintain its luster. Be gentle to avoid scratching the metal or any softer stones in the setting.
  • Proper Storage: When not wearing your ring, store it in a pouch or a jewelry box. This way, you’ll never lose track of your stunning ring. 
  • Activity Use: Moissanite is a durable gemstone, so you don’t need to worry about scratching it. It’s best to remove your ring during activities like cleaning, washing dishes, working out, doing laundry, or any other activities that may be hard on your hands.
  • Removing Oil Slicks: Routine cleaning with a soft cloth and mild jewelry cleaner will help prevent oil slicks from forming. Avoid exposure to cleaning products, perfumes, and other harsh substances that can leave residue on the moissanite.

Follow these steps to ensure your moissanite keeps shining for decades.
