Every week we get the same email: What's the difference between solid 14K and 14K gold-plated? Here's the answer we wish someone had given us when we started.
Solid gold
Solid gold means the entire piece — top, bottom, inside, and out — is the same gold alloy. There is no other metal underneath.
- 10K is 41.7% pure gold, 58.3% other alloys (usually copper, silver, zinc). Durable, holds shape well, slightly more yellow-warm than 14K.
- 14K is 58.3% pure gold. The American standard for fine jewelry. Strong enough for daily wear, rich color.
- 18K is 75% pure gold. Softer than 10K or 14K — better for occasional wear, more saturated yellow.
Every solid gold piece we sell carries a real karat stamp (10K, 14K, or 18K) on the inside of the band, the back of the bail, or the clasp. The stamp is mandatory under US law for fine jewelry.
Gold-plated
Gold-plated means a base metal (usually sterling silver or brass) with a thin layer of gold electroplated on the surface. The thickness varies wildly between manufacturers.
- Standard gold plating is about 0.5 microns thick. Wears off in 6–12 months of daily wear.
- Heavy gold plating is 2–3 microns. Lasts 2–5 years with normal care.
- Vermeil is gold-plated sterling silver with a minimum 2.5 micron layer. The most durable plating standard.
Gold-filled
Gold-filled is a thicker, mechanically bonded layer of gold over a base metal — much more durable than plating but not as durable as solid gold. It's heavier, more expensive than plating, and lasts decades with normal care. We use this construction occasionally for chain pieces where solid gold would be cost-prohibitive.
What we call what
We're strict about labeling because the jewelry industry is loose about it.
- If a piece is solid gold, we say "Solid 10K" or "Solid 14K."
- If a piece is plated, we say "Gold-Plated Sterling Silver" or "Gold-Plated" — never just "Gold."
- If a piece is gold-tone (color but not gold content), we say "Gold-Tone."
- If a piece is vermeil, we say "Vermeil."
Which should you buy?
Honest answer: it depends on how often you'll wear it and what you want from it.
- Daily wear, lifetime piece, heirloom: Solid 10K or 14K. Stamped, appraisable, repairable.
- Trendy stack pieces, weekly rotation, $40–80 budget: Gold-plated sterling silver. Lasts years with care.
- Costume layering, fashion-only: Gold-tone or fashion alloy. Cheap, fun, replaceable.
A solid 14K paperclip chain costs $300–500. A gold-plated sterling paperclip costs $50–80. Both are good products. They're for different uses.
How to tell what you have
Look for the stamp. Inside a ring, on the back of a pendant bail, on the clasp of a chain.
- 10K, 14K, 18K — solid gold
- 925 — sterling silver (likely plated if it looks gold)
- 14K GP, 14K GE, 14K HGE, 14K HGP — gold-plated
- 14K GF — gold-filled
- 14K Vermeil — vermeil
- No stamp — fashion piece, not fine jewelry
