What are Gold Filled, Rolled Gold, and Gold Plate?
Share
You will occasionally see markings describing jewelry items as Gold Filled, Rolled Gold, or Gold Plate. Â In the US these terms are regulated by the Federal Trade Commission (FTC). Â
Gold Filled (GF) indicates that at least 5% of the marked gold purity, usually 14k or 10k, by weight, is gold. Â So, for example, a 30 gram 14k GF bracelet will contain at least 1.5 grams (5%) of 14k. Â Rolled Gold Plate (RGP), at one time used interchangeably with Gold Filled, today has a bit less gold, typically 3.33% by weight. So for that same 30 gram bracelet it would contain 0.99 gram of 14k. Â Gold Plate on the other hand, can have as little at 0.05% of the marked gold purity. Â For the same 30 gram bracelet, gold plate would be 0.015 gram - a significant difference. Â The following table provides a summary of differences.
| Type | Application Method | Minimum Gold Requirement | Typical Gold % by Weight | Relative Durability | Approx. Gold Thickness vs. Plating |
|---|---|---|---|---|---|
| Gold Filled | Mechanical bonding | ≥1/20 (5%) of total metal weight | ~5%+ | High (years) | 50–100x thicker |
| Rolled Gold Plate | Mechanical bonding | <1/20 (with fraction disclosed, e.g., 1/40) | 1–4.9% | Medium | 10–50x thicker |
| Gold Plate | Electroplating | No weight % minimum; very thin layer | <<1% | Low (months–few years) | Baseline (thinnest) |
In summary, gold filled has the most gold content and best longevity, rolled gold plate is a step down but still far better than gold plate, and gold plate has the least gold (mostly a cosmetic thin coating). For value and wear resistance, gold filled is generally the best "middle ground" option between solid gold and basic plating. Always check for FTC-compliant markings on items to verify claims.
