Yellow Gold
Yellow gold has a warm, classic color shaped by gold purity and its alloy recipe. Compare 14K and 18K for differences in gold content, tone, wear, and feel rather than treating either as universally better.

Precious Metals
Color, purity, character, and care — the materials that shape how a piece looks and lives.
Meet the Metals
White Gold
White gold is a gold alloy with a white appearance. Many pieces use a rhodium finish; construction, wear, and the appearance you prefer can affect whether periodic refinishing is appropriate.
Learn moreRose Gold
Rose gold is a warm, copper-toned gold alloy. Its exact color varies with gold purity and the maker’s alloy recipe, so two rose-gold pieces may not match perfectly.
Learn morePlatinum
Platinum is a naturally white precious metal valued for density and durability. It can develop a soft patina with wear and may be professionally refinished when a brighter finish is preferred.
Learn morePurity & Composition
What the marks mean.
Karat describes gold purity; carat describes diamond weight. The alloy metals that make up the remainder influence strength, workability, and color.
| Metal | Precious-metal content | Why alloy metals are used | What to verify |
|---|---|---|---|
| 14K Gold | 14/24 gold · about 58.3% | Strength, workability, and color | Karat mark and exact piece details |
| 18K Gold | 18/24 gold · 75% | Strength, workability, and color | Karat mark and exact piece details |
| Platinum | Typically a high-purity platinum alloy | Wearability and working properties | Exact fineness marked or verified on the piece |

How Metal Changes the Look
One silhouette. A different impression.
Metal tone can influence how a ring and diamond are perceived, especially at the prongs, shank, and around accent stones. These are educational studies, not representations of a specific available product.
Wear, Care & Maintenance
Every finish records a life.
All precious metals can scratch and show wear. Prong design, setting construction, activity, and routine inspection matter as much as the alloy choice.
Read Ownership & Care
- White gold may need periodic rhodium refinishing depending on construction, wear, and desired appearance.
- Platinum can develop patina and can be professionally refinished.
- Rose and yellow gold should be cleaned gently and inspected like other fine jewelry.
- Settings and prongs should be checked for security as part of ongoing care.
