Checking Necklaces and Chains With Magnets

Practical Guide to Spotting Fake Metals in Your Jewelry

Many people have old necklaces, chains, or broken jewelry tucked away in drawers. Before selling or sending these items for appraisal, it helps to know whether they are real gold or silver, or if they are plated or entirely base metal. One of the simplest home tests you can do is the magnet test. This article explains how to perform it correctly, what its limits are, and how it fits into a larger step-by-step process for identifying, sorting, packing, mailing, and getting paid for unwanted precious metals.

Step 1: Understanding the Magnet Test

A magnet test checks whether your necklace or chain is attracted to a strong magnet. Most real gold and silver are not magnetic. If your chain leaps to the magnet, it’s a sign that it may be steel, nickel, or another base metal. However, an item that does not stick to a magnet is not guaranteed to be genuine precious metal. Fake pieces can be made with non-magnetic alloys as well.

How to Do the Magnet Test Safely

• Use a neodymium (rare-earth) magnet. These are stronger than fridge magnets and can be easily found online or at hardware stores.

• Hold your necklace or chain close to the magnet. Move slowly to see if any part reacts.

• Note your results, but don’t consider this conclusive proof of authenticity.

Step 2: Look for Stamps and Hallmarks

After the magnet test, visually inspect your necklace or chain. Genuine gold usually carries hallmarks such as 10K, 14K, 18K, 22K, or 24K. Silver items often carry marks like 925, Sterling, or occasionally older symbols such as "Coin" or "800." These marks are often small and may require a magnifying glass or loupe to see clearly.

Step 3: Weighing Your Jewelry

Use a small digital pocket scale that measures in grams. Record the weight of each chain or necklace. This number helps you estimate melt value later and makes quoting with a buyer much faster. Be sure to keep gemstones or clasps attached unless you are experienced and comfortable removing them.

Step 4: Recording and Logging Your Results

After magnet testing, stamp checking, and weighing, create a simple record. Write down each item’s description, weight, stamp, and magnet result. Taking photos is also helpful. If you plan to request a mail-in quote, logging these details online ensures a faster, more accurate estimate. Some people use note-taking apps or even spreadsheets. For those who prefer structured tools, GavelBase can be used to organize and track items safely.

Step 5: Preparing to Mail Your Jewelry

If you decide to sell, you can request a free, tracked mailer kit from a reputable buyer. Key steps for safe shipping include:

• Place your necklace in a small sealed bag or padded envelope inside a larger shipping package.

• If you have tiny chain links or fragments, group them together so they are not lost.

• Use a carrier with insured and trackable service. See USPS Registered Mail & Insurance to understand your options.

Step 6: What Testing to Expect

After mailing, the buyer will verify the authenticity of your items using clear testing methods. Common approaches include acid testing, electronic testers, and XRF (X-ray fluorescence) analysis. You should expect to receive transparent results showing karat, weight, and payout value.

Step 7: Understanding Value

The value of your chain depends on purity, weight, and current market price. Keep in mind:

• Melt Value: What your chain is worth if melted down for metal content.

• Offer Value: What a buyer pays after accounting for refining costs, handling, and non-gold or non-silver parts.

Step 8: Getting Paid

Today’s gold and silver buyers usually offer several secure payment options. Common methods include:

• PayPal: Fast, widely used, may have small fees.

• Venmo: Quick, convenient mobile transfers.

• Zelle: Instant transfers direct to bank accounts, but may have daily limits.

• Cash App: Instant payout, app-based, also has balance limits.

• ACH or Direct Deposit: Often free, but can take 1–2 business days.

• Check: Reliable, but slowest option by mail.

Quick Checklist

• Use the magnet test but don’t rely on it alone.

• Look for karat stamps and sterling marks.

• Weigh your items in grams.

• Log weight, stamps, and test results with photos.

• Pack small items securely before mailing.

• Use insured, trackable shipping methods.

• Expect clear testing and transparent payment options.

FAQ

Does passing the magnet test mean my necklace is real gold?

No. It only rules out certain fake metals. Further testing is always needed.

Can gold-plated items pass the magnet test?

Yes. Plated items often are made from non-magnetic base metals. Only detailed testing shows whether something is solid gold or simply plated.

Do I need to remove stones or clasps?

Only if you are comfortable. Most buyers will weigh the full piece and adjust for stones. Removing them without the right tools may damage the item.

What about dental gold?

Dental crowns or bridges often contain 12K to 18K gold mixed with porcelain or steel. Separate any non-metal parts carefully and pack securely before mailing.

Final Thoughts

The magnet test is a useful first step in checking your necklaces and chains. When combined with other simple tests, accurate weighing, and good record-keeping, it provides a foundation for understanding what you own. Logging results before you mail items makes the valuation and payment process faster and clearer. Ultimately, these steps help you make informed decisions about your unwanted precious metals in a safe, secure, and efficient way.
