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. In the US these terms are regulated by the Federal Trade Commission (FTC).
Gold Filled (GF) indicates that at least 5% of the marked gold purity, usually 14k or 10k, by weight, is gold. So, for example, a 30 gram 14k GF bracelet will contain at least 1.5 grams (5%) of 14k. 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. Gold Plate on the other hand, can have as little at 0.05% of the marked gold purity. For the same 30 gram bracelet, gold plate would be 0.015 gram - a significant difference. 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.
