Does Moissanite Tarnish? The Ultimate Guide

Table of Contents

Moissanite has grown increasingly popular over time as an affordable yet gorgeous diamond alternative gemstone. But with any precious stone comes questions of its long-term durability and appearance. One such concern among potential buyers is tarnishing. In this guide, we aim to answer this query while providing more insight into Moissanite’s lifespan and resilience.

History of Moissanite

Understanding Moissanite requires going back to its origins. Contrary to popular belief, Moissanite was not created artificially but was discovered in 1893 by Dr. Henri Moissan of France who found small quantities in meteorite craters; initially mistaking them for diamonds due to their hardness and brilliance.

Moissanite Properties

Moissanite is well known for its hardness, ranking 9.25 on Mohs’ Scale just behind Diamond’s 10 ranking. Additionally, Moissanite exhibits exceptional brilliance and fire that rivals that of diamond, often being confused with this precious gemstone. Furthermore, Moissanite shares with only diamond thermal conductivity among popular gemstones.

Does Moissanite Tarnish?

In short, no. Moissanite is made up of silicon carbide – a chemical compound resistant to discoloration – making it highly durable against wear and tear, keeping its beautiful sparkle for life – an invaluable characteristic that makes Moissanite an excellent choice for engagement rings and other fine jewelry pieces.

Why Moissanite Doesn’t Tarnish?

Understanding why Moissanite doesn’t tarnish requires an understanding of its inherent qualities. Hardness and chemical stability are among the major contributors to its non-tarnishing nature.

1. Exceptional Hardness

Moissanite stands out as an exceptional hardness gem with a score of 9.25 on the Mohs hardness scale – harder than any other gemstone except diamond! This hardness ensures it resists scratches, abrasions and maintains its luster over time.

2. Chemical Stability

Moissanite’s composition of silicon carbide makes it chemically inert, meaning that its stable composition won’t interact with common elements or compounds – contributing to its non-tarnishing property.

Comparing Moissanite to Other Gemstones

Moissanite’s durability and brilliance have caused it to be often compared with other precious stones; but how does it compare?

Moissanite Vs Diamond

Diamond is one of the hardest materials known, boasting a high refractive index. But Moissanite surpasses diamond in terms of brilliance and fire. Furthermore, mining of Moissanite presents less ethical concerns, making it a more sustainable solution.

Moissanite Vs Cubic Zirconia

Cubic Zirconia is an increasingly popular diamond alternative, but over time its sparkle can fade and scratch off, while Moissanite retains its sparkle and integrity, setting itself apart from Cubic Zirconia.

Care of Moissanite Jewelry

While Moissanite jewelry does not tarnish, proper care should still be taken to preserve its brilliance. A gentle solution and soft toothbrush should help maintain its brilliance; harsh chemicals or abrasive materials that could scratch its metal setting should be avoided to preserve its brilliance.

When not wearing moissanite jewelry, store it separately from other pieces to prevent scratching. A jewelry box with fabric-lined compartments or individual pouches works well for keeping moissanite safe.


Does Moissanite Lose its Sparkle Over Time?

No, Moissanite does not fade over time. In fact, its fire and brilliance remain undiminished, making it the ideal choice for daily wear.

Can Moissanite become scratched?

Moissanite may not be as hard as diamond, but it remains unlikely to get scratched under normal use. Moissanite rates 9.25 on Mohs scale – making it one of the hardest substances known.

Are Moissanite products eco-friendly?

Moissanite is an eco-friendly choice; unlike diamond mining processes, its production does not harm the environment.

Are You Wondering If Moissanite Can Be Cleaned with Vinegar?

Yes, vinegar can be used to clean Moissanite jewelry. Mix equal parts vinegar and warm water in equal proportions before gently brushing it on with a soft toothbrush.

How often should I clean my Moissanite jewelry?

For optimal shine, it is recommended that Moissanite jewelry be cleaned at least once every month.


Moissanite stands out among gemstones in that its brilliance will never fade over time, making it ideal for long-term jewelry designs and applications. Thanks to its exceptional hardness and chemical stability, its vibrant surface shines for many decades without ever losing its brilliance or becoming dull over time – an unrivaled gem!

Other Tips

1) Measure your finger in warm temperatures at the end of the day.

2) If your knuckle is a lot larger than the base of your finger, measure both the base of your finger and your knuckle and select a size between the two.

3) When considering a wide band, move up a size from your measurement, for comfort’s sake.
