Moissanite has a strong fan club now, yet many buyers still feel nervous about long term shine. Don’t worry, moissanite does not tarnish or lose its color over time! The reason is because it is not a metal.
This guide answers a few simple doubts. Does moissanite tarnish over time? Can it stay bright for years? What sort of care is needed for achieving that longevity?
Let us break down how moissanite reacts to air and daily life. We’ll check how to care for your watch or ring in a simple routine.
A recent survey of almost 17,000 couples found that around 52% of engagement rings now use a lab-grown centre stone.

What Does Tarnish Really Mean For Jewellery
Most people use the word tarnish for any dull patch on metal or stone. In reality, tarnish has a specific meaning. It is a chemical change on the surface of a metal due to contact with air or moisture or chemicals. That thin layer can look dark, cloudy, or slightly coloured.
Diamonds, moissanite, and many lab stones do not tarnish in that strict sense. They do not form a new layer on the surface. They can look dull because of dirt deposits or scratches on the surface around them. Metal parts near the stone can also change colour, which makes the whole piece look older.
The US jewellery market made about $75.8 billion in revenue in 2024, with rings as the biggest product segment, so a lot of money depends on pieces staying bright.
Tarnish Versus Dirt and Product Build Up
Dull shine on a watch dial or ring does not always signal damage. Often it is just a buildup of hand cream or soap or small dust particles. These sit on top of the stone and block light. The stone under that film still has the same sparkle.
One US survey shows fewer than 3% of jewellery wearers clean their pieces regularly, and over half only clean them once they already look dull.
A quick clean clears that layer in many cases. That is why a cloudy patch that vanishes after gentle cleaning is not true tarnish. It is surface grime.
Why Some Metals Darken Over Time
Silver reacts fast to air and sweat, so it can turn grey quite quickly. Some lower grade gold alloys can also show slight tone change with heavy use. This change sits on the metal surface and can spread around settings near the stone.
If a moissanite piece uses soft or thin plating, that metal can lose shine long before the stone changes. Buyers then think the whole piece has aged. In truth, the stone still behaves well. High grade settings, like those used by Glazed Diamonds in the moissanite watches, lower this risk and keep the luxury look intact for longer years.
Does Moissanite Tarnish or Lose Its Sparkle
The short answer in plain language is that moissanite does not tarnish. It can look dull, but that effect comes out of dirt film, worn metal near the stone, or tiny scratches on the surface created by rough contact. The crystal itself does not react with air the way silver or low grade metal can.
How Moissanite Reacts to Air, Water and Skin
Moissanite has a very stable structure. Normal air, tap water, or clean skin contact do not change the stone. That stability is one big reason luxury brands now pick moissanite for heavy wear pieces like watches and engagement rings.
Heat in daily life also stays within safe limits. Shower steam, a cup of tea in hand, or short walks in harsh sun do not disturb the stone. Only extreme heat treatment in a lab or workshop can create a deeper impact, which usual customers never face.
Common Myths About Moissanite Going Yellow
One common myth says moissanite always turns yellow with time. High quality stones stay clear. Yellow tint usually shows up due to three issues. A warm metal under the stone that reflects colour, old oils that make light scatter in a strange way, or very low grade stones cut in a poor way.
Another myth claims moissanite loses shine faster than diamond. In reality, moissanite has higher brilliance than diamond in many lighting angles. A dull look usually means the piece needs one simple clean. Brands that use strict grading, such as Glazed Diamonds, test each stone for cut and clarity so the piece keeps that strong sparkle for daily wear.
How To Care For Moissanite So It Stays Bright
Good news is that caring for moissanite feels simple once you know the basics. You do not need fancy solutions or salon visits each month. A short home routine plus smart wear habits can keep a watch dial or ring face bright for many years.
Habits That Keep Your Watch or Ring Fresh
Small daily choices do a lot for long term shine. Take your moissanite watch off during heavy weight training or deep cleaning with strong products. Put it on after make up, hair spray, or perfume, not before. This avoids sticky layers on the surface.
Store jewellery in a pouch so pieces do not rub hard against each other. Use a case that holds the strap in shape for the watches. A quick wipe with a clean cloth at night removes dust before storage. It slows down metal marks too.

FAQs On Moissanite Care and Tarnish
Does moissanite tarnish over time like silver?
No. Moissanite does not react with air in the same way as silver. It can look dull due to dirt film, but the stone surface does not form a tarnish layer.
Can moissanite turn yellow after a few years of wear?
High grade moissanite stays clear. Yellow tones usually come out of warm metal reflections, old oil buildup, or very low quality stones used in cheaper settings.
Why does my moissanite watch look cloudy right now?
Cloudy patches often point to hand cream or dust gathered on the crystal. A gentle clean with mild soap will fix this.
How often should I clean my moissanite watch at home?
Do a quick clean every two or three weeks. Clean more often if you use many products on your hands or work in a dusty space daily.
Is moissanite a safe pick for daily wear compared to diamond?
Yes. Moissanite has strong hardness and stable shine. With a solid setting by a trusted brand like Glazed Diamonds, it works very well for daily watches, rings, or bracelets.
