Gold-Bonded vs Solid Gold: What Is the Difference?

Short answer: Solid gold is gold throughout the piece, so it cannot wear through to another metal. Gold-bonded jewelry has a layer of gold bonded onto a core of another metal. At My Jewelry Connect, that is 14K gold over .925 sterling silver. It offers the gold look with a different structure, and the gold layer can wear down over time. Neither is a fake when labeled honestly, but they are different products.

What each term means

Solid gold is an alloy of gold and other metals, measured in karats. 10K is 41.7% gold, 14K is 58.3% and 18K is 75%. The whole piece is that alloy, from surface to center.

Gold-bonded jewelry has a layer of gold attached to a base metal using heat and pressure. Ours is 14K gold bonded over a .925 sterling silver core. The gold is on the surface only.

Gold-plated jewelry has a very thin layer of gold deposited on the surface, usually by an electrical process. The layer is typically much thinner than bonded or filled layers.

Gold-filled is a regulated term in the United States. It describes a thick layer of karat gold, bonded by heat and pressure, that makes up at least 1/20 of the item's total weight.

Sterling silver (.925) is 92.5% silver, mixed with other metal, usually copper, for strength. Silver is a different metal from gold and appears in a white color unless it is coated.

Gold-bonded is a trade term, not a federally defined standard like "gold-filled." Because of that, ask what the layer is and what is under it. We state ours: 14K gold-bonded over .925 sterling silver.

How long does gold-bonded last?

It depends on how it is worn. The gold layer sits on the surface, so friction, sweat, lotions, chlorine and rubbing against clothing gradually wear it. A piece worn occasionally can look good for a long time. A chain worn every day through workouts and showers will wear sooner. Once the layer thins, the silver color of the core can show through, and a jeweler cannot easily restore it the way they can polish or repair solid gold. We do not promise a specific lifespan.

Who should buy which

Choose solid gold if: - You want a piece you can wear daily for years, and plan to keep. - You want to be able to repair, resize or repolish it. - You want to know that the metal is gold throughout.

Choose gold-bonded if: - You want the gold look at a lower entry point. - You want to try a style, such as a wide Cuban link, before committing to solid gold. - You wear it occasionally or as a fashion piece.

Choose sterling silver if: - You prefer the white color of silver. - You want an everyday metal and do not mind occasional polishing.

Care tips for gold-bonded pieces

• Take it off before showers, swimming, workouts and cleaning.
• Put on lotion and perfume first, then the jewelry.
• Wipe with a soft dry cloth after wearing.
• Do not use abrasive cleaners or polishing cloths with harsh compounds.
• Store pieces separately so they do not scratch each other.

FAQ

Is gold-bonded the same as gold-plated? No. Both put gold on the surface of a base metal. Plating is typically a much thinner coating, and bonding attaches a gold layer using heat and pressure. Both are surface layers.

Is gold-bonded jewelry real gold? The surface layer is real gold, 14K in our pieces, but the piece is not solid gold. Its core is .925 sterling silver.

Will gold-bonded jewelry turn my skin green? It is less likely while the gold layer is intact. Skin reactions vary by person, and a worn layer exposes the core metal.

Can I mix solid gold and gold-bonded? Yes. Many people wear a solid gold piece they love with gold-bonded pieces for variety.
