Yes. Wedding and engagement rings can use different metals, but hardness, color, finish, and contact wear should be considered.

Visual reasons to mix metals

Mixed-metal stacks can connect other jewelry, create contrast, or make a warm center band stand out beside white metal.

Wear considerations

Rings that touch can polish, scratch, or abrade one another over time. Differences in hardness do not guarantee that only the softer metal will show wear; the contact pattern, finish, dirt, and movement also matter.

Color maintenance

White gold may require periodic rhodium replating to maintain a bright white surface, while platinum develops a patina. Yellow and rose gold change differently with wear.

Choose metals for the desired appearance and maintenance expectations, and inspect close-contact stacks periodically.
