Gold Types Explained
Gold Types Explained
Not all gold jewelry is created equal. Before you invest in a piece, here's everything you need to know about gold types, karats, and what they mean for your jewelry.
Solid Gold vs. Gold-Plated vs. Gold-Filled
| Type | What It Is | Durability | Value |
|---|---|---|---|
| Solid Gold | Gold alloy throughout the entire piece | Lifetime — tarnish-resistant, doesn't wear off | Highest |
| Gold-Filled | Thick gold layer bonded to base metal | Years of regular wear | Mid-range |
| Gold-Plated | Thin gold layer electroplated over base metal | Months to 1–2 years depending on wear | Budget-friendly |
Gold Karats: What Do They Mean?
Karat (K) measures the purity of gold — how much of the alloy is pure gold versus other metals. Other metals are added to increase hardness and adjust color.
- 24K Gold — 99.9% pure gold. Too soft for most jewelry. Used in investment bars and coins.
- 18K Gold — 75% pure gold. Rich color, excellent durability. The choice for fine luxury jewelry.
- 14K Gold — 58.3% pure gold. Excellent balance of purity and durability. The most popular choice in the USA.
- 10K Gold — 41.7% pure gold. Most durable, most affordable. Minimum karat legally sold as gold in the USA.
Gold Color Varieties
- Yellow Gold — Classic warm tone. Natural gold color. Timeless and universally flattering.
- White Gold — Yellow gold alloyed with white metals (palladium or nickel), usually rhodium-plated. Cool, silver-like appearance.
- Rose Gold — Gold alloyed with copper. Warm pinkish tone. Romantic and modern.
