Checking If Jewelry Is Solid Gold or Just Plated

Understanding Solid Gold vs. Plated Jewelry

Many people come across old rings, chains, coins, or even dental gold and wonder whether these items are solid gold or just plated. Knowing the difference is essential before selling, mailing in, or requesting an appraisal. Identifying whether your jewelry is solid gold, gold-filled, or electroplated can help you avoid disappointment and set realistic expectations.

Step 1: Read the Stamps and Hallmarks

The most reliable first step is to look for markings stamped on the jewelry:

• Karat markings: 10K, 14K, 18K, 22K, 24K indicate solid gold content. The higher the number, the higher the purity.

• Common gold-plated marks: GP (gold plated), GF (gold filled), HGE (heavy gold electroplate), RGP (rolled gold plate).

• Silver markings: .925, Sterling, or “Ster.” generally indicate sterling silver.

If the jewelry is unstamped, it may still be gold, but you’ll need to test it to be sure.

Step 2: Do a Simple Magnet Test

Hold a strong magnet near your item. Gold and silver are not magnetic. If your jewelry sticks, it is either plated or contains non-precious metals. Note, however, that clasp springs and fillers may contain magnetic parts.

Step 3: Weight and Density Check

Solid gold items feel heavy for their size compared to plated jewelry. Use a small digital scale (grams preferred) to weigh the piece. Matching weight with karat markings can help verify authenticity. For example, a solid 18K wedding band of typical size should feel noticeably denser than a gold-plated version.

Step 4: Testing Methods

If you are still unsure, several common testing methods can help:

• Acid test kit: A jeweler’s acid test can help detect karat by observing how the metal reacts when a drop of acid is applied after making a small scratch (done in a safe spot). Use caution—acid is hazardous.

• Electronic gold testers: These test conductivity and provide fast results.

• Professional testing: Mail-in services or jewelers often provide detailed results, including photos and documentation.

For more on measurement accuracy, review standards from NIST.

Step 5: Sorting and Preparing Your Items

Before mailing or bringing items in for evaluation:

• Sort items by karat if known.

• Keep smaller items in secure bags or envelopes.

• Label lots: "14K," "Sterling," "Unmarked."

• Remove any non-metal parts safely if possible (stones, clasps).

Handling Dental Gold

Dental gold is often 16K to 22K and may still be worth significant value even when broken or mixed with porcelain or steel. Separate what you can, but avoid forcing materials apart. A professional buyer can remove metal for weighing and testing.

Understanding Melt Value vs. Offer Value

Melt value is based purely on precious metal content and current market prices per gram. Offer value may be lower because buyers account for: refining costs, removing non-precious materials, and assay fees. Coins or collectible items may carry additional numismatic value beyond melt.

Shipping Your Items Securely

If you choose to mail in your gold, silver, or other valuables, follow these steps:

1. Request a free appraisal or mailer kit from a trusted source.

2. Package securely: wrap items individually, use padded mailers or boxes.

3. Insure your package: For U.S. residents, explore USPS insurance and Registered Mail for maximum protection. FedEx and UPS also provide shipping insurance.

4. Track shipment and retain your receipt for peace of mind.

Payment Options You Can Expect

Depending on your preference, payment methods typically include:

Safety, Records, and Organization

Taking simple steps will protect you and keep the process smooth:

• Photograph each item before you send it.

• Keep notes on weight, markings, and expectations.

• Store all correspondence and quotes in one place. For personal organization, tools like GavelBase can help you log descriptions and photos.

Quick Checklist

• Look for markings (10K, 14K, GP, GF, HGE).

• Do a magnet test.

• Weigh in grams.

• Sort by category before sending (gold, silver, unknown).

• Package securely and ship insured.

• Track your package.

• Choose your preferred payment method.

Frequently Asked Questions

How can I tell if my jewelry is gold plated or solid?

Check for markings like GP, GF, or HGE. Use a magnet test or ask for professional testing if the item is unmarked.

Is plated jewelry worth selling?

Gold plating contains very little actual gold. It usually holds minimal melt value, though some vintage or luxury brands may retain fashion value.

Can I mail in dental gold safely?

Yes. Pack securely, use insurance and tracking, and consider separating porcelain pieces if easy and safe to do so.

Why is the payout less than melt value?

Buyers deduct processing and refining costs when making offers. This explains the difference between theoretical melt value and the cash offer.

What is the fastest way to get paid?

Digital payments such as Zelle, PayPal, Cash App, or Venmo are often the fastest, while checks and ACH direct deposit may take longer.

Final Thoughts

By learning to recognize karat stamps, identifying plating marks, confirming with magnet or acid tests, and organizing your items, you can make informed decisions about selling gold, silver, and dental metals. Careful packing, insured shipping, and clear records ensure your items are handled safely and that you receive fair and prompt payment.
