Why My Silver Necklace Turned Copper Color?
There are two possible reasons your silver jewelry has turned a copper color, and it's worth knowing which one applies to you. Either the piece isn't solid silver and the plating has worn through to the copper base metal underneath, or the piece is solid sterling silver that has tarnished, which can sometimes take on a coppery or darkened tone rather than the classic black tarnish most people expect.
If It's Worn Plating
Plated jewelry is made from a base metal, often copper, coated with a thin layer of silver. Over time, that silver layer wears away with regular use, and the copper underneath becomes visible. Once this happens, there's not much to do beyond having the piece re-plated or replacing it. If avoiding this in the future matters to you, the simplest fix is buying solid silver rather than plated pieces next time.
Genuine solid silver jewelry doesn't have to be expensive. It can sometimes cost less than plated pieces from less reputable sellers. The key is buying from a reputable dealer and checking for a hallmark, a small stamp certifying the metal's purity, usually applied by an assay office.
A genuine sterling silver hallmark reads “925” or “.925”, meaning the piece is 92.5% pure silver. Pure silver on its own is too soft for jewelry, since it dents and bends too easily, so 7.5% of another metal, usually copper, gets added for strength.
If It's Genuine Tarnish
It's important not to mistake worn plating for solid silver that has simply tarnished. All solid silver tarnishes eventually. It's impossible to avoid entirely, since it comes from a natural oxidization process, and it can happen faster in certain environments, like humid climates or with frequent exposure to lotions and perfumes. For a full breakdown of why this happens and how to prevent it, see our guide on whether 925 silver tarnishes and how to stop it.
A few options exist for dealing with it. Many people choose to have their silver rhodium plated, which is durable and hard-wearing, though even rhodium plating can eventually wear through to the silver underneath. E-coating is another option: a clear protective layer that preserves the silver's natural look rather than covering it with another metal. Silver lacquer is a third choice, though it can yellow over time and becomes difficult to remove once it does, which makes it less appealing as a long-term fix than plating or e-coating.
How to Clean Tarnished Silver
If a piece has already tarnished, polishing it with a proper silver polish removes the oxidized top layer and reveals the fresher metal underneath. It's worth using a light touch, since over-polishing can round off sharp details or wear away fine engraving over time. A soft cloth and gentle, even strokes work better than aggressive scrubbing.

FAQ
Why did my silver necklace turn copper colored?
Either the piece is plated and the silver layer has worn through to the copper base underneath, or it's genuine solid silver that has tarnished, which can sometimes take on a coppery tone rather than the classic black tarnish.
How can I tell if my necklace is plated or solid silver?
Check for a “925” or “.925” hallmark, which indicates solid sterling silver. Plated jewelry typically won't carry this mark. Weight and a simple polish test can also help confirm which one you have.
Can a copper-colored necklace be fixed?
If it's worn plating, the piece can be re-plated by a jeweler, though this comes at a cost similar to buying a new piece in some cases. If it's tarnish on solid silver, a proper silver polish will restore its original finish.
Does all silver eventually tarnish?
Yes. All solid sterling silver tarnishes over time due to its copper content reacting with air and moisture. It's a normal process, not a sign of poor quality, and it can be slowed with proper storage and care.
What's the best way to prevent this from happening again?
Buying solid sterling silver rather than plated jewelry avoids the wear-through issue entirely. For genuine silver, a protective finish like rhodium plating or e-coating slows tarnish considerably, along with proper storage between wears.
